Examples of org.objectweb.asm.ClassVisitor.visitMethod()

org.objectweb.asm.ClassVisitor.visitMethod()
Visits a method of the class. This method must return a new {@link CodeVisitor CodeVisitor} instance (or null) each time itis called, i.e., it should not return a previously returned visitor. @param access the method's access flags (see {@link Constants}). This parameter also indicates if the method is synthetic and/or deprecated. @param name the method's name. @param desc the method's descriptor (see {@link Type Type}). @param exceptions the internal names of the method's exceptionclasses (see {@link Type#getInternalName() getInternalName}). May be null. @param attrs the non standard method attributes, linked together by theirnext field. May be null. @return an object to visit the byte code of the method, or null ifthis class visitor is not interested in visiting the code of this method.
