Method Detail

containsKey

public boolean containsKey(double key)

Description copied from interface: Double2CharFunction

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 Double2CharFunction

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

See Also:
