public class ResourceType 
extends java.lang.Object

Utility class containing constants. Type of loaded resource.

Example:

Shows how to process inserted resources differently.
public void resourceLoadingCallback() throws Exception {
    Document doc = new Document();

    // Images belong to NodeType.Shape
    // There are none in a blank document
    Assert.assertEquals(doc.getChildNodes(NodeType.SHAPE, true).getCount(), 0);

    // Enable our custom image loading
    doc.setResourceLoadingCallback(new ImageNameHandler());

    DocumentBuilder builder = new DocumentBuilder(doc);

    // We usually insert images as a uri or byte array, but there are many other possibilities with ResourceLoadingCallback
    // In this case we are referencing images with simple names and keep the image fetching logic somewhere else
    builder.insertImage("Google Logo");
    builder.insertImage("Aspose Logo");
    builder.insertImage("My Watermark");

    Assert.assertEquals(doc.getChildNodes(NodeType.SHAPE, true).getCount(), 3);

    doc.save(getArtifactsDir() + "DocumentBase.ResourceLoadingCallback.docx");
