containsKey
public boolean containsKey(java.lang.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.
- Specified by:
containsKey
in interfaceFunction<K,java.lang.Long>
- Parameters:
key
- the key.- Returns:
- true if this function associates a value to
key

Description copied from interface:Object2LongFunction
Returns the value to which the given key is mapped.- Specified by:
getLong
in interfaceObject2LongFunction<K>
- Parameters:
key
- the key.- Returns:
- the corresponding value, or the default return value if no value was present for the given key.
