Class Verifier
java.lang.Object
org.apache.bcel.verifier.Verifier
public class Verifier
extends java.lang.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.

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.
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.
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.
getMessages
public String[] getMessages()
This returns all the (warning) messages collected during verification.
A prefix shows from which verifying pass a message originates.
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)').
