Method Detail

getChildren

List<Filter> getChildren()

Returns a list containing all of the child filters of this object. This list will contain at least two elements, and each element will be an instance of Filter. Implementations of this interface are encouraged to return either a copy of their internal list or an immutable wrapper around their internal list. This is because this specification requires Filter objects to be immutable.
