Method Detail

defaultValue

byte defaultValue()

Returns the default value of this map, which is used instead of null in primitive specialization methods, when the key is absent in the map.

Returns:

the default value of this map

See Also:

ByteByteMapFactory.withDefaultValue(byte)

containsKey

@Deprecated
boolean containsKey(Object key)

Deprecated. Use specialization containsKey(byte) instead

Returns true if this map contains a mapping for the specified key. More formally, returns true if and only if this map contains a mapping for a key k such that (key==null ? k==null : key.equals(k)). (There can be at most one such mapping.)

Specified by:

containsKey in interface Map<Byte,Byte>

Parameters:

key - key whose presence in this map is to be tested

Returns:

true if this map contains a mapping for the specified key

containsKey

boolean containsKey(byte key)

Returns true if this map contains a mapping for the specified key.

Parameters:

key - the byte key whose presence in this map is to be tested

Returns:

true if this map contains a mapping for the specified key

containsValue

@Deprecated
boolean containsValue(Object value)

Deprecated. Use specialization containsValue(byte) instead

Returns true if this map maps one or more keys to the specified value. More formally, returns true if and only if this map contains at least one mapping to a value v such that (value==null ? v==null : value.equals(v)). This operation will probably require time linear in the map size for most implementations of the Map interface.

Specified by:

containsValue in interface Map<Byte,Byte>

Parameters:

value - value whose presence in this map is to be tested

Returns:

true if this map maps one or more keys to the specified value

containsValue

boolean containsValue(byte value)

Returns true if this map maps one or more keys to the specified value. This operation will probably require time linear in the map size for most implementations of the ByteByteMap interface.

Parameters:

value - the byte value whose presence in this map is to be tested

Returns:

true if this map maps one or more keys to the specified value

get

@Nullable
 @Deprecated
Byte get(Object key)

Deprecated. Use specialization get(byte) instead

Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.

More formally, if this map contains a mapping from a key k to a value v such that (key==null ? k==null : key.equals(k)), then this method returns v; otherwise it returns null. (There can be at most one such mapping.)

If this map permits null values, then a return value of null does not necessarily indicate that the map contains no mapping for the key; it's also possible that the map explicitly maps the key to null. The containsKey operation may be used to distinguish these two cases.

Specified by:

get in interface Map<Byte,Byte>

Parameters:

key - the key whose associated value is to be returned

Returns:

the value to which the specified key is mapped, or null if this map contains no mapping for the key

get

byte get(byte key)

Returns the value to which the specified key is mapped, or default value if this map contains no mapping for the key.

Parameters:

key - the key whose associated value is to be returned

Returns:

the value to which the specified key is mapped, or default value if this map contains no mapping for the key

getOrDefault

@Deprecated
Byte getOrDefault(Object key,
                               Byte defaultValue)

Deprecated. Use specialization getOrDefault(byte, byte) instead

Returns the value to which the specified key is mapped, or defaultValue if this map contains no mapping for the key.

Specified by:

Returns:

the value to which the specified key is mapped, or defaultValue if this map contains no mapping for the key

getOrDefault

Parameters:

key - the key whose associated value is to be returned

defaultValue - the value to return if the specified key is absent in the map

Returns:

the value to which the specified key is mapped, or defaultValue if this map contains no mapping for the key

forEach

@Deprecated
void forEach(@Nonnull
                          java.util.function.BiConsumer<? super Byte,? super Byte> action)

Deprecated. Use specialization forEach(ByteByteConsumer) instead

Performs the given action for each entry in this map until all entries have been processed or the action throws an exception. Unless otherwise specified by the implementing class, actions are performed in the order of entry set iteration (if an iteration order is specified.) Exceptions thrown by the action are relayed to the caller.

Specified by:

forEach in interface Map<Byte,Byte>

Parameters:

action - The action to be performed for each entry

forEach

void forEach(@Nonnull
             ByteByteConsumer action)

Performs the given action on each entry in this map until all entries have been processed or the action throws an Exception. Exceptions thrown by the action are relayed to the caller. The entries will be processed in the same order as the entry set iterator unless that order is unspecified in which case implementations may use an order which differs from the entry set iterator.

Parameters:

action - The action to be performed for each entry

See Also:

Comparison of iteration options in the library

forEachWhile

boolean forEachWhile(@Nonnull
                     ByteBytePredicate predicate)

Checks the given predicate on each entry in this map until all entries have been processed or the predicate returns false for some entry, or throws an Exception. Exceptions thrown by the predicate are relayed to the caller.

The entries will be processed in the same order as the entry set iterator unless that order is unspecified in which case implementations may use an order which differs from the entry set iterator.

If the map is empty, this method returns true immediately.

Parameters:

predicate - the predicate to be checked for each entry

Returns:

true if the predicate returned true for all entries of the map, false if it returned false for the entry

See Also:

Comparison of iteration options in the library

cursor

@Nonnull

Returns:

a new cursor over the entries of this map

See Also:

Comparison of iteration options in the library

keySet

@Nonnull
ByteSet keySet()

Description copied from interface: java.util.Map

Returns a Set view of the keys contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations.

Specified by:

keySet in interface Map<Byte,Byte>

Returns:

a set view of the keys contained in this map

values

@Nonnull
ByteCollection values()

Description copied from interface: java.util.Map

Returns a Collection view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa. If the map is modified while an iteration over the collection is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The collection supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Collection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.

Specified by:

values in interface Map<Byte,Byte>

Returns:

a collection view of the values contained in this map

entrySet

@Nonnull
ObjSet<Map.Entry<Byte,Byte>> entrySet()

Description copied from interface: java.util.Map

Returns a Set view of the mappings contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation, or through the setValue operation on a map entry returned by the iterator) the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.

Specified by:

entrySet in interface Map<Byte,Byte>

Returns:

a set view of the mappings contained in this map

                      Byte value)

Deprecated. Use specialization put(byte, byte) instead

Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value. (A map m is said to contain a mapping for a key k if and only if m.containsKey(k) would return true.)

Specified by:

put in interface Map<Byte,Byte>

Parameters:

key - key with which the specified value is to be associated

value - value to be associated with the specified key

Returns:

the previous value associated with key, or null if there was no mapping for key. (A null return can also indicate that the map previously associated null with key, if the implementation supports null values.)

byte put(byte key,
         byte value)

Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value. (A map m is said to contain a mapping for a key k if and only if m.containsKey(k) would return true.)

Parameters:

key - key with which the specified value is to be associated

value - value to be associated with the specified key

Returns:

the previous value associated with key, or default value if there was no mapping for key. (A default value return can also indicate that the map previously associated default value with key.)

compute

@Deprecated
Byte compute(Byte key,

                          java.util.function.BiFunction<? super Byte,? super Byte,? extends Byte> remappingFunction)

Deprecated. Use specialization compute(byte, ByteByteToByteFunction) instead

Attempts to compute a mapping for the specified key and its current mapped value (or null if there is no current mapping). For example, to either create or append a String msg to a value mapping:

 
 map.compute(key, (k, v) -> (v == null) ? msg : v.concat(msg))

(Method merge() is often simpler to use for such purposes.)

If the function returns null, the mapping is removed (or remains absent if initially absent). If the function itself throws an (unchecked) exception, the exception is rethrown, and the current mapping is left unchanged.

Specified by:

compute in interface Map<Byte,Byte>

Parameters:

key - key with which the specified value is to be associated

remappingFunction - the function to compute a value

Returns:

the new value associated with the specified key, or null if none

compute

byte compute(byte key,
             @Nonnull
             ByteByteToByteFunction remappingFunction)

Attempts to compute a mapping for the specified key and its current mapped value (or default value if there is no current mapping).

If the function itself throws an (unchecked) exception, the exception is rethrown, and the current mapping is left unchanged.

Parameters:

key - key with which the specified value is to be associated

Returns:

the new value associated with the specified key

Throws:

UnsupportedOperationException - if the put operation is not supported by this map

Deprecated. Use specialization computeIfAbsent(byte, ByteUnaryOperator) instead

If the specified key is not already associated with a value (or is mapped to null), attempts to compute its value using the given mapping function and enters it into this map unless null.

If the function returns null no mapping is recorded. If the function itself throws an (unchecked) exception, the exception is rethrown, and no mapping is recorded. The most common usage is to construct a new object serving as an initial mapped value or memoized result, as in:

 
 map.computeIfAbsent(key, k -> new Value(f(k)));
 

Or to implement a multi-value map, Map<K,Collection<V>>, supporting multiple values per key:

 
 map.computeIfAbsent(key, k -> new HashSet<V>()).add(v);
 

Specified by:

computeIfAbsent in interface Map<Byte,Byte>

Parameters:

key - key with which the specified value is to be associated

mappingFunction - the function to compute a value

Returns:

the current (existing or computed) value associated with the specified key, or null if the computed value is null

                        java.util.function.BiFunction<? super Byte,? super Byte,? extends Byte> remappingFunction)

Deprecated. Use specialization merge(byte, byte, ByteBinaryOperator) instead

If the specified key is not already associated with a value or is associated with null, associates it with the given non-null value. Otherwise, replaces the associated value with the results of the given remapping function, or removes if the result is null. This method may be of use when combining multiple mapped values for a key. For example, to either create or append a String msg to a value mapping:

 
 map.merge(key, msg, String::concat)

function - the function to apply to each entry

Throws:

UnsupportedOperationException - if the set operation is not supported by this map's entry set iterator

IllegalArgumentException - if some property of a replacement value prevents it from being stored in this map (optional restriction)

remove

@Nullable
 @Deprecated
Byte remove(Object key)

Deprecated. Use specialization remove(byte) instead

Removes the mapping for a key from this map if it is present (optional operation). More formally, if this map contains a mapping from key k to value v such that (key==null ? k==null : key.equals(k)), that mapping is removed. (The map can contain at most one such mapping.)

Returns the value to which this map previously associated the key, or null if the map contained no mapping for the key.

If this map permits null values, then a return value of null does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to null.

The map will not contain a mapping for the specified key once the call returns.

Specified by:

remove in interface Map<Byte,Byte>

Parameters:

key - key whose mapping is to be removed from the map

Returns:

the previous value associated with key, or null if there was no mapping for key.

remove

byte remove(byte key)

Removes the mapping for a key from this map if it is present (optional operation).

Returns the value to which this map previously associated the key, or default value if the map contained no mapping for the key.

A return value of default value does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to default value.

The map will not contain a mapping for the specified key once the call returns.

Parameters:

key - key whose mapping is to be removed from the map

Returns:

the previous value associated with key, or default value if there was no mapping for key

Throws:

UnsupportedOperationException - if the remove operation is not supported by this map

remove

@Deprecated
boolean remove(Object key,
                            Object value)

Deprecated. Use specialization remove(byte, byte) instead

Removes the entry for the specified key only if it is currently mapped to the specified value.

Specified by:

remove in interface Map<Byte,Byte>

Parameters:

key - key with which the specified value is associated

value - value expected to be associated with the specified key

Returns:

true if the value was removed

Throws:

NullPointerException - if the specified key or value is null

UnsupportedOperationException - if the remove operation is not supported by this map

remove

boolean remove(byte key,
               byte value)

Removes the entry for the specified key only if it is currently mapped to the specified value.

Parameters:

key - key with which the specified value is associated

value - value expected to be associated with the specified key

Returns:

true if the value was removed

Throws:

UnsupportedOperationException - if the remove operation is not supported by this map

removeIf

boolean removeIf(@Nonnull
                 ByteBytePredicate filter)

Removes all of the entries of this collection that satisfy the given predicate. Errors or runtime exceptions thrown during iteration or by the predicate are relayed to the caller.

Parameters:

filter - a predicate which returns true for elements to be removed

Returns:

true if any elements were removed

Throws:

NullPointerException - if the specified filter is null

UnsupportedOperationException - if elements cannot be removed from this collection. Implementations may throw this exception if a matching element cannot be removed or if, in general, removal is not supported.
