Method Detail

test

@Deprecated
public boolean test(int operand)

Deprecated. Please use the corresponding type-specific method instead.

In this default implementation, the key gets narrowed down to the actual key type, throwing an exception if the given key can't be represented in the restricted domain. This is done for interoperability with the Java 8 function environment. Its use is discouraged, as unexpected errors can occur. Instead, the corresponding classes should be used (e.g., Int2IntFunction instead of Short2IntFunction).

test in interface Short2BooleanFunction

Specified by:

test in interface java.util.function.IntPredicate

apply

@Deprecated
public java.lang.Boolean apply(java.lang.Short key)

Deprecated. Please use the corresponding type-specific method instead.

This is equivalent to calling Function.get(Object).

Specified by:

apply in interface java.util.function.Function<java.lang.Short,java.lang.Boolean>

Parameters:

key -

Returns:

See Also:

Function.apply(Object), Function.get(Object)

size

public int size()

Description copied from interface: Function

Returns the intended number of keys in this function, or -1 if no such number exists.

Most function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible. This default implementation, in particular, returns -1.

Returns:

the intended number of keys in this function, or -1 if that number is not available.

defaultReturnValue

public boolean defaultReturnValue()

Description copied from interface: Short2BooleanFunction

Gets the default return value.

This default implementation just return the default null value of the type (null for objects, 0 for scalars, false for Booleans).

Specified by:

defaultReturnValue in interface Short2BooleanFunction

Returns:

the current default return value.

defaultReturnValue

public void defaultReturnValue(boolean defRetValue)

Description copied from interface: Short2BooleanFunction

Sets the default return value (optional operation). This value must be returned by type-specific versions of get(), put() and remove() to denote that the map does not contain the specified key. It must be 0/false/null by default.

Specified by:

defaultReturnValue in interface Short2BooleanFunction

Parameters:

defRetValue - the new default return value.

See Also:

Short2BooleanFunction.defaultReturnValue()

containsKey

public boolean containsKey(short k)

Description copied from interface: Short2BooleanFunction

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

Note that for some kind of functions (e.g., hashes) this method will always return true. In particular, this default implementation always returns true.

Specified by:

containsKey in interface Short2BooleanFunction

Parameters:

k - the key.

Returns:

true if this function associates a value to key.

See Also:

Function.containsKey(Object)

containsKey

@Deprecated
public boolean containsKey(java.lang.Object k)

Deprecated.

Description copied from interface: Short2BooleanFunction

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

Note that for some kind of functions (e.g., hashes) this method will always return true. This default implementation, in particular, always return true.

Specified by:

containsKey in interface Short2BooleanFunction

Parameters:

k - the key.

Returns:

true if this function associates a value to key.

See Also:

Map.containsKey(Object)

put

public boolean put(short k,
                   boolean v)

Description copied from interface: Short2BooleanFunction

Adds a pair to the map (optional operation).

Specified by:

put in interface Short2BooleanFunction

Parameters:

k - the key.

v - the value.

Returns:

the old value, or the default return value if no value was present for the given key.

See Also:

Function.put(Object,Object)

get

public boolean get(short k)

Description copied from interface: Short2BooleanFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Short2BooleanFunction

Parameters:

k - the key.

Returns:

the corresponding value, or the default return value if no value was present for the given key.

See Also:

Function.get(Object)

remove

public boolean remove(short k)

Description copied from interface: Short2BooleanFunction

Removes the mapping with the given key (optional operation).

Specified by:

remove in interface Short2BooleanFunction

Parameters:

k - the key.

Returns:

the old value, or the default return value if no value was present for the given key.

See Also:

Function.remove(Object)

clear

public void clear()

Description copied from interface: Function

Removes all associations from this function (optional operation).

See Also:

Map.clear()

put

@Deprecated
public java.lang.Boolean put(java.lang.Short k,
                                         java.lang.Boolean v)

Deprecated. Please use the corresponding type-specific method instead.

Associates the specified value with the specified key in this function (optional operation).

Specified by:

put in interface Short2BooleanFunction

Parameters:

k - the key.

v - the value.

Returns:

the old value, or null if no value was present for the given key.

See Also:

Map.put(Object,Object)

get

@Deprecated
public java.lang.Boolean get(java.lang.Object k)

Deprecated. Please use the corresponding type-specific method instead.

Returns the value associated by this function to the specified key.

Specified by:

get in interface Short2BooleanFunction

Parameters:

k - the key.

Returns:

the corresponding value, or null if no value was present for the given key.

Map.get(Object)

remove

@Deprecated
public java.lang.Boolean remove(java.lang.Object k)

Deprecated. Please use the corresponding type-specific method instead.

Removes this key and the associated value from this function if it is present (optional operation).

Specified by:

remove in interface Short2BooleanFunction

k - the key.

Returns:

the old value, or null if no value was present for the given key.
