Method Detail

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.

Specified by:

size in interface Function<Float,Short>

Returns:

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

containsKey

public boolean containsKey(float k)

Specified by:

containsKey in interface Float2ShortFunction

See Also:

Function.containsKey(Object)

defaultReturnValue

public short defaultReturnValue()

Description copied from interface: Float2ShortFunction

Gets the default return value.

Specified by:

defaultReturnValue in interface Float2ShortFunction

Overrides:

defaultReturnValue in class AbstractFloat2ShortFunction

Returns:

the current default return value.

defaultReturnValue

public void defaultReturnValue(short defRetValue)

Description copied from interface: Float2ShortFunction

Sets the default return value. 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 Float2ShortFunction

Overrides:

defaultReturnValue in class AbstractFloat2ShortFunction

Parameters:

defRetValue - the new default return value.

See Also:

Float2ShortFunction.defaultReturnValue()

put

public short put(float k,
        short v)

Description copied from interface: Float2ShortFunction

Adds a pair to the map.

Specified by:

put in interface Float2ShortFunction

Overrides:

put in class AbstractFloat2ShortFunction

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)

clear

public void clear()

Description copied from interface: Function

Removes all associations from this function (optional operation).

Specified by:

clear in interface Function<Float,Short>

Overrides:

clear in class AbstractFloat2ShortFunction

See Also:

Map.clear()

toString

public String toString()

Overrides:

toString in class Object

remove

public short remove(float k)

Description copied from interface: Float2ShortFunction

Removes the mapping with the given key.

Specified by:

remove in interface Float2ShortFunction

Overrides:

remove in class AbstractFloat2ShortFunction

Returns:

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

See Also:

Function.remove(Object)

get

public short get(float k)

Description copied from interface: Float2ShortFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Float2ShortFunction

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)

containsKey

public boolean containsKey(Object ok)

Description copied from interface: Function

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.

Specified by:

containsKey in interface Function<Float,Short>

Overrides:

containsKey in class AbstractFloat2ShortFunction

Parameters:

ok - the key.

Returns:

true if this function associates a value to key.
