public abstract class AddTraceStatementsAction
extends java.lang.Object
implements org.eclipse.ui.IActionDelegate

The purpose of AddTraceStatementsAction is to demonstrate how to add simple code modifications ("refactoring") to the Java editor. This action is an abstract implementation for those subclasses wishing to add trace statements for each method, including all parameters, one or more methods.

Method Detail

addTraceStatement

protected void addTraceStatement(org.eclipse.jdt.core.dom.MethodDeclaration md,
                                 org.eclipse.jdt.core.IBuffer buffer)
Adds a garden-variety trace statement to the given method, using System.out.println. Subclasses may override to add more sophisticated trace statements.

createTraceStatement

public java.lang.String createTraceStatement(org.eclipse.jdt.core.dom.MethodDeclaration md,
                                             java.lang.String source,
                                             boolean format)
Given a MethodDeclaration, return a source System.out.println listing the method name and parameters. 
 System.out.println("Start " + method + "<" p1 + ">");

This method handles the cases where the parameter doesn't understand the toString (or at least tries).

selectionChanged

public void selectionChanged(org.eclipse.jface.action.IAction action,
                             org.eclipse.jface.viewers.ISelection selection)
Selection has changed, the default is to do nothing. Subclasses can override to fit their needs, e.g., test for the type of selection or singularity.
