Package org.mvel2.compiler

Class PropertyVerifier

java.lang.Object

org.mvel2.compiler.AbstractParser

org.mvel2.optimizers.AbstractOptimizer

org.mvel2.compiler.PropertyVerifier

All Implemented Interfaces:

Serializable, Parser

public class PropertyVerifier
extends AbstractOptimizer

This verifier is used by the compiler to enforce rules such as type strictness. It is, as side-effect, also responsible for extracting type information.
