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.Boolean>
- Parameters:
key
- the key.- Returns:
- true if this function associates a value to
key
. - See Also:
Map.containsKey(Object)

getBoolean
public boolean getBoolean(java.lang.Object key)
Description copied from interface:Reference2BooleanFunction
Returns the value to which the given key is mapped.- Specified by:
getBoolean
in interfaceReference2BooleanFunction<K>
- Parameters:
key
- the key.- Returns:
- the corresponding value, or the default return value if no value was present for the given key.
- See Also:
Function.get(Object)

getOrDefault
public boolean getOrDefault(java.lang.Object key, boolean defaultValue)
Description copied from interface:Reference2BooleanFunction
Returns the value associated by this function to the specified key, or give the specified value if not present.- Specified by:
getOrDefault
in interfaceReference2BooleanFunction<K>
- Parameters:
key
- the key.defaultValue
- the value to return if not present.- Returns:
- the corresponding value, or
defaultValue
if no value was present for the given key. - See Also:
