Method Detail

containsKey

public boolean containsKey(Object key)

Description copied from interface: Function

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. This default implementation, in particular, always return true.

Parameters:

key - the key.

Returns:

true if this function associates a value to key.
