      • doCopy

        protected TextEdit doCopy()
        Description copied from class: TextEdit
        Creates and returns a copy of this edit. The copy method should be implemented in a way so that the copy can executed without causing any harm to the original edit. Implementors of this method are responsible for creating deep or shallow copies of referenced object to fulfill this requirement.

        Implementers of this method should use the copy constructor Edit#Edit(Edit source) to initialize the edit part of the copy. Implementors aren't responsible to actually copy the children or to set the right parent.

        This method should not be called from outside the framework. Please use copy to create a copy of a edit tree.

      • accept0

        protected void accept0​(TextEditVisitor visitor)
        Description copied from class: TextEdit
        Accepts the given visitor on a type-specific visit of the current edit. This method must be implemented in all concrete text edits.

        General template for implementation on each concrete TextEdit class:

         
         boolean visitChildren= visitor.visit(this);
         if (visitChildren) {
            acceptChildren(visitor);
         }
         
         
        Note that the caller (accept) takes care of invoking visitor.preVisit(this) and visitor.postVisit(this).

        accept0 in class TextEdit
        Parameters:
        visitor - the visitor object
