Class PropertyVerifier

java.lang.Object
  org.mvel2.compiler.AbstractParser
      org.mvel2.optimizers.AbstractOptimizer
          org.mvel2.compiler.PropertyVerifier

All Implemented Interfaces:

java.io.Serializable

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.
