Method Detail

containsKey

public boolean containsKey(char key)

Description copied from interface: Char2IntFunction

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 Char2IntFunction

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

See Also:

Function.containsKey(Object)

@Deprecated
public boolean containsKey(Object key)

Deprecated.

Specified by:

containsKey in interface Char2IntFunction

Specified by:

containsKey in interface Function<Character,Integer>

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

Description copied from interface: Char2IntFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Char2IntFunction

Parameters:

key - the key.
