Class ConstraintParser

java.lang.Object

org.drools.model.codegen.execmodel.generator.drlxparse.ConstraintParser

public class ConstraintParser
extends Object

Parses the MVEL String Constraint and compiles it to a Java Expression There are two kinds of ConstraintParser ConstraintParser#defaultConstraintParser ConstraintParser#withoutVariableValidation There are some cases (such as from, eval) in which variables are allowed in the constraint
