Class TextEditVisitor
java.lang.Object
org.eclipse.text.edits.TextEditVisitor
-
public class TextEditVisitor
- extends
Object
A visitor for text edits.
For each different concrete text edit type T there is a method:
-
public boolean visit(T node) - Visits the given edit to
perform some arbitrary operation. If true is returned, the given edit's
child edits will be visited next; however, if false is returned, the
given edit's child edits will not be visited. The default implementation provided by
this class calls a generic method visitNode(TextEdit node).
Subclasses may reimplement these method as needed.
In addition, there are methods for visiting text edits in the
abstract, regardless of node type:
-
public void preVisit(TextEdit edit) - Visits
the given edit to perform some arbitrary operation.
This method is invoked prior to the appropriate type-specific
visit method.
The default implementation of this method does nothing.
Subclasses may reimplement this method as needed.
-
public void postVisit(TextEdit edit) - Visits
the given edit to perform some arbitrary operation.
This method is invoked after the appropriate type-specific
endVisit method.
The default implementation of this method does nothing.
Subclasses may reimplement this method as needed.
For edits with children, the child nodes are visited in increasing order.
