Method Detail

size

public int size()

defaultReturnValue

public V defaultReturnValue()

Description copied from interface: Short2ObjectFunction

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 Short2ObjectFunction<V>

Overrides:

defaultReturnValue in class AbstractShort2ObjectFunction<V>

Returns:

the current default return value.

defaultReturnValue

public void defaultReturnValue(V defRetValue)

Description copied from interface: Short2ObjectFunction

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 Short2ObjectFunction<V>

Overrides:

defaultReturnValue in class AbstractShort2ObjectFunction<V>

Parameters:

defRetValue - the new default return value.

Short2ObjectFunction.defaultReturnValue()

containsKey

public boolean containsKey(short k)

Description copied from interface: Short2ObjectFunction

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 Short2ObjectFunction<V>

Parameters:

k - the key.

Returns:

true if this function associates a value to key.

See Also:

Function.containsKey(Object)

put

public V put(short k,
             V v)

Description copied from interface: Short2ObjectFunction

Adds a pair to the map (optional operation).

Specified by:

put in interface Short2ObjectFunction<V>

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 V get(short k)

Description copied from interface: Short2ObjectFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Short2ObjectFunction<V>

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 V remove(short k)

Description copied from interface: Short2ObjectFunction

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

Specified by:

remove in interface Short2ObjectFunction<V>

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()

put

@Deprecated
public V put(java.lang.Short k,
                         V 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 Short2ObjectFunction<V>

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 V 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 Short2ObjectFunction<V>

Parameters:

k - the key.

Returns:

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

See Also:

Map.get(Object)

remove

@Deprecated
public V 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 Short2ObjectFunction<V>

Parameters:

k - the key.

Returns:

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