Class VariableContextScriptBindings

java.lang.Object

org.camunda.bpm.dmn.engine.impl.el.VariableContextScriptBindings

All Implemented Interfaces:

Map<String,Object>, Bindings

public class VariableContextScriptBindings
extends Object
implements Bindings

A Script Bindings implementation wrapping a provided VariableContext and Bindings instance. Enhances the Bindings with the variables resolvable through the VariableContext. The variables are treated as read only: all mutating operations write through to the wrapped Bindings.
