Package org.drools.mvelcompiler

Class LHSPhase

java.lang.Object

org.drools.mvelcompiler.LHSPhase

All Implemented Interfaces:

com.github.javaparser.ast.visitor.GenericVisitor<TypedExpression,Void>, org.drools.mvel.parser.ast.visitor.DrlGenericVisitor<TypedExpression,Void>

public class LHSPhase
extends Object
implements org.drools.mvel.parser.ast.visitor.DrlGenericVisitor<TypedExpression,Void>

This phase processes the left hand side of a MVEL target expression, if present, such as int a = 0 b = 2 It also creates a new AST with the transformation rules applied i.e. person.name = "Name"; becomes person.setName("Name");
