public class OneBlock

extends java.lang.Object

A one argument function block. The value(Object) function should be overrided to provided the implementation of the function block. This will typicaly be done inline. e.g. new OneBlock() { public Object value(Object arg1) { return (((Boolean)arg1) == Boolean.TRUE) ? Boolean.FALSE : Boolean.TRUE } } The above trivial example is a OneBlock that takes an argument, casts it to a Boolean and returns the inverse of the argument. This function could be mapped over a collection of Booleans to produce the NOT of the collection.
