org.shapelogic.scripting
Class FunctionPredicate<In>

java.lang.Object
  org.shapelogic.scripting.BaseScriptingFunction
      org.shapelogic.scripting.FunctionPredicate<In>

All Implemented Interfaces:

Calc1<In,java.lang.Object>, Predicate<In>

public class FunctionPredicate<In>
extends BaseScriptingFunction
implements Predicate<In>, Calc1<In,java.lang.Object>

Transform based on an expression in a Scripting language using JSR 223. Requires Groovy to be installed. Need special installation of groovy-engine.jar that need to be downloade from Sun. Requires that the scripting language support the invocable interface.
