Constructor Detail

MethodCriteriaClassVisitor

public MethodCriteriaClassVisitor(org.objectweb.asm.ClassVisitor injector,
                                  org.objectweb.asm.ClassVisitor bypass)

Method Detail

setCriteria

public void setCriteria(MethodCriteria criteria)

visit

public void visit(int version,
                  int access,
                  java.lang.String name,
                  java.lang.String signature,
                  java.lang.String superName,
                  java.lang.String[] interfaces)

when this method is called MethodCriteria.isMatch(className) is checked to see if any injection is necessary. If not, then the default visitor is set to bypass the injection process.

Specified by:

visit in interface org.objectweb.asm.ClassVisitor

visitMethod

public org.objectweb.asm.MethodVisitor visitMethod(int access,
                                                   java.lang.String name,
                                                   java.lang.String desc,
                                                   java.lang.String signature,
                                                   java.lang.String[] exceptions)

when this method is called MethodCriteria.isMatch(className, methodName, ...) is checked to see if any injection is necessary for this method. If not, then the bypass visitor is used. Otherwise, the default visitor is used (which was set in the class visit method).
