Method Details

containsKey

public boolean containsKey(long key)

Description copied from interface: Long2CharFunction

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 Long2CharFunction

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

See Also:

• Function.containsKey(Object)

Description copied from interface: Long2CharFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Long2CharFunction

Parameters:

key - the key.

Returns:

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