                                        char value)
Method Detail

containsKey

public boolean containsKey(float k)
Specified by:
containsKey in interface Float2CharFunction
See Also:
Function.containsKey(Object)

get

public char get(float k)
Description copied from interface: Float2CharFunction
Returns the value to which the given key is mapped.

Specified by:
get in interface Float2CharFunction
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,Character>
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
