containsKey
public boolean containsKey(int key)
Description copied from interface:Int2CharFunction
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 interfaceInt2CharFunction
- Parameters:
key
- the key.- Returns:
- true if this function associates a value to
key
. - See Also:
Function.containsKey(Object)
