## Methods

| Method | Description |
| --- | --- |
| [getAction()](#getAction) | Gets a value indicating what type of node change event is occurring. |
| [getNewParent()](#getNewParent) | Gets the node's parent that will be set after the operation completes. |
| [getNode()](#getNode) | Gets the [getNode()](../../com.aspose.words/nodechangingargs/\#getNode) that is being added or removed. |
| [getOldParent()](#getOldParent) | Gets the node's parent before the operation began. |
### getAction() {#getAction}
```
public int getAction()
```


Gets a value indicating what type of node change event is occurring.

 **Examples:** 

Shows how to use a NodeChangingCallback to monitor changes to the document tree in real-time as we edit it.

```

 public void nodeChangingCallback() throws Exception {
     Document doc = new Document();
     doc.setNodeChangingCallback(new NodeChangingPrinter());

     DocumentBuilder builder = new DocumentBuilder(doc);
     builder.writeln("Hello world!");
     builder.startTable();
     builder.insertCell();
     builder.write("Cell 1");
     builder.insertCell();
     builder.write("Cell 2");
     builder.endTable();

     builder.insertImage(getImageDir() + "Logo.jpg");
     builder.getCurrentParagraph().getParentNode().removeAllChildren();
 }

 /// 
 /// Prints every node insertion/removal as it takes place in the document.
 /// 
 private static class NodeChangingPrinter implements INodeChangingCallback {
     public void nodeInserting(NodeChangingArgs args) {
         Assert.assertEquals(args.getAction(), NodeChangingAction.INSERT);
         Assert.assertEquals(args.getOldParent(), null);
     }

     public void nodeInserted(NodeChangingArgs args) {
         Assert.assertEquals(args.getAction(), NodeChangingAction.INSERT);
         Assert.assertNotNull(args.getNewParent());

         System.out.println("Inserted node:");
         System.out.println(MessageFormat.format("\tType:\t{0}", args.getNode().getNodeType()));

         if (!"".equals(args.getNode().getText().trim())) {
             System.out.println(MessageFormat.format("\tText:\t\"{0}\"", args.getNode().getText().trim()));
         }

         System.out.println(MessageFormat.format("\tHash:\t{0}", args.getNode().hashCode()));
         System.out.println(MessageFormat.format("\tParent:\t{0} ({1})", args.getNewParent().getNodeType(), args.getNewParent().hashCode()));
     }

     public void nodeRemoving(NodeChangingArgs args) {
         Assert.assertEquals(args.getAction(), NodeChangingAction.REMOVE);
     }

     public void nodeRemoved(NodeChangingArgs args) {
         Assert.assertEquals(args.getAction(), NodeChangingAction.REMOVE);
         Assert.assertNull(args.getNewParent());

         System.out.println(MessageFormat.format("Removed node: {0} ({1})", args.getNode().getNodeType(), args.getNode().hashCode()));
     }
 }
 
```

**Returns:**
int - A value indicating what type of node change event is occurring. The returned value is one of [NodeChangingAction](../../com.aspose.words/nodechangingaction/) constants.
