accept	back to summary
public void accept(CodeBuilder builder, CodeElement element) Implements java.lang.classfile.ClassFileTransform.accept. Doc from java.lang.classfile.ClassFileTransform.accept. Transform an element by taking the appropriate actions on the builder. Used when transforming a classfile entity (class, method, field, method body.) If no transformation is desired, the element can be presented to `B#with(ClassFileElement)`. If the element is to be dropped, no action is required. This method is called by the Class-File API. Users should never call this method. Annotations @Override
