Class Verifier


  • public class Verifier
    extends Object
    A Verifier instance is there to verify a class file according to The Java Virtual Machine Specification, 2nd Edition. Pass-3b-verification includes pass-3a-verification; pass-3a-verification includes pass-2-verification; pass-2-verification includes pass-1-verification. A Verifier creates PassVerifier instances to perform the actual verification. Verifier instances are usually generated by the VerifierFactory.

    • Method Detail

      • doPass1

        public VerificationResult doPass1()
        Returns the VerificationResult for the given pass.
      • doPass2

        public VerificationResult doPass2()
        Returns the VerificationResult for the given pass.
      • doPass3a

        public VerificationResult doPass3a​(int method_no)
        Returns the VerificationResult for the given pass.
      • doPass3b

        public VerificationResult doPass3b​(int method_no)
        Returns the VerificationResult for the given pass.
      • getClassName

        public final String getClassName()
        Returns the name of the class this verifier operates on. This is particularly interesting when this verifier was created recursively by another Verifier and you got a reference to this Verifier by the getVerifiers() method of the VerifierFactory.

      • flush

        public void flush()
        Forget everything known about the class file; that means, really start a new verification of a possibly different class file from BCEL's repository.
      • main

        public static void main​(String[] args)
        Verifies class files. This is a simple demonstration of how the API of BCEL's class file verifier "JustIce" may be used. You should supply command-line arguments which are fully qualified namea of the classes to verify. These class files must be somewhere in your CLASSPATH (refer to Sun's documentation for questions about this) or you must have put the classes into the BCEL Repository yourself (via 'addClass(JavaClass)').
