Method Detail

containsKey

public boolean containsKey(float k)

Specified by:

containsKey in interface Float2FloatFunction

See Also:

Function.containsKey(Object)

get

public float get(float k)

Description copied from interface: Float2FloatFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Float2FloatFunction

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)

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,Float>

Returns:

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

clone

public Object clone()

Overrides:

clone in class Object
