Method Details

containsKey

public boolean containsKey(char key)

Description copied from interface: Char2LongFunction

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 Char2LongFunction

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

See Also:

• Function.containsKey(Object)

Specified by:

containsKey in interface Char2LongFunction

Specified by:

containsKey in interface Function<Character,Long>

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

get

public long get(char key)

Description copied from interface: Char2LongFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Char2LongFunction

Parameters:

key - the key.

Returns:

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

getOrDefault

public long getOrDefault(char key,
 long defaultValue)

Description copied from interface: Char2LongFunction

Returns the value associated by this function to the specified key, or give the specified value if not present.

Specified by:

Parameters:

key - the key.

defaultValue - the value to return if not present.

Returns:

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