Class LayoutEnumerator

  • java.lang.Object
    • com.aspose.words.LayoutEnumerator
public class LayoutEnumerator 
extends java.lang.Object

Enumerates page layout entities of a document. You can use this class to walk over the page layout model. Available properties are type, geometry, text and page index where entity is rendered, as well as overall structure and relationships. Use combination of LayoutCollector.getEntity(com.aspose.words.Node) and Current move to the entity which corresponds to a document node.

Example:

Shows ways of traversing a document's layout entities.
public void layoutEnumerator() throws Exception {
    // Open a document that contains a variety of layout entities.
    // Layout entities are pages, cells, rows, lines, and other objects included in the LayoutEntityType enum.
    // Each layout entity has a rectangular space that it occupies in the document body.
    Document doc = new Document(getMyDir() + "Layout entities.docx");

    // Create an enumerator that can traverse these entities like a tree.
    LayoutEnumerator layoutEnumerator = new LayoutEnumerator(doc);

    Assert.assertEquals(doc, layoutEnumerator.getDocument());

    layoutEnumerator.moveParent(LayoutEntityType.PAGE);

    Assert.assertEquals(LayoutEntityType.PAGE, layoutEnumerator.getType());
    Assert.assertThrows(IllegalStateException.class, () -> System.out.println(layoutEnumerator.getText()));

    // We can call this method to make sure that the enumerator will be at the first layout entity.
    layoutEnumerator.reset();

    // There are two orders that determine how the layout enumerator continues traversing layout entities
    // when it encounters entities that span across multiple pages.
    // 1 -  In visual order:
    // When moving through an entity's children that span multiple pages,
    // page layout takes precedence, and we move to other child elements on this page and avoid the ones on the next.

Initializes new instance of this class.
 
Property Getters/Setters Summary

booleanmoveFirstChild()
Moves to the first child entity.
booleanmoveLastChild()

        public LayoutEnumerator(Document document)
                         throws java.lang.Exception
        Initializes new instance of this class.

        If page layout model of the document hasn't been built the enumerator calls Document.updatePageLayout() to build it.

        Whenever document is updated and new page layout model is created, a new enumerator must be used to access it.

        Parameters:
        document - A document whose page layout model to enumerate.

      • movePreviousLogical

        Moves to the previous sibling entity in a logical order. When iterating lines of a paragraph broken across pages this method will move to the previous line even if it resides on another page. Note that all LayoutEntityType.SPAN entities are linked together thus if Current entity is span repeated calling of this method will iterates complete story of the document.
