Class FieldListNum

  • java.lang.Object
    • Field
      • com.aspose.words.FieldListNum
public class FieldListNum 
extends Field

Implements the LISTNUM field.

Example:

Shows how to number paragraphs with LISTNUM fields.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Insert a list num field using a document builder
FieldListNum field = (FieldListNum) builder.insertField(FieldType.FIELD_LIST_NUM, true);

// Lists start counting at 1 by default, but we can change this number at any time
// In this case, we'll do a zero-based count
field.setStartingNumber("0");
builder.writeln("Paragraph 1");

Assert.assertEquals(" LISTNUM  \\s 0", field.getFieldCode());

// Placing several list num fields in one paragraph increases the list level instead of the current number,
// in this case resulting in "1)a)i)", list level 3
builder.insertField(FieldType.FIELD_LIST_NUM, true);
builder.insertField(FieldType.FIELD_LIST_NUM, true);
builder.insertField(FieldType.FIELD_LIST_NUM, true);
builder.writeln("Paragraph 2");

// The list level resets with new paragraphs, so to keep counting at a desired list level, we need to set the ListLevel property accordingly
field = (FieldListNum) builder.insertField(FieldType.FIELD_LIST_NUM, true);
field.setListLevel("3");
builder.writeln("Paragraph 3");

Assert.assertEquals(" LISTNUM  \\l 3", field.getFieldCode());

field = (FieldListNum) builder.insertField(FieldType.FIELD_LIST_NUM, true);

// Setting this property to this particular value will emulate the AUTONUMOUT field
field.setListName("OutlineDefault");

Assert.assertTrue(field.hasListName());
Assert.assertEquals(" LISTNUM  OutlineDefault", field.getFieldCode());

// Start counting from 1
field.setStartingNumber("1");
builder.writeln("Paragraph 4");

// Our fields keep track of the count automatically, but the ListName needs to be set with each new field
field = (FieldListNum) builder.insertField(FieldType.FIELD_LIST_NUM, true);
field.setListName("OutlineDefault");
builder.writeln("Paragraph 5");

doc.updateFields();
doc.save(getArtifactsDir() + "Field.LISTNUM.docx");

      • remove

        public Node remove()
                   throws java.lang.Exception
        Removes the field from the document. Returns a node right after the field. If the field's end is the last child of its parent node, returns its parent paragraph. If the field is already removed, returns null.

        Example:

        Shows how to work with a document's field collection.
        public void fieldCollection() throws Exception {
            // Create a new document and insert some fields

      • unlink

        public boolean unlink()
                      throws java.lang.Exception
        Performs the field unlink.

        Replaces the field with its most recent result.

        Some fields, such as XE (Index Entry) fields and SEQ (Sequence) fields, cannot be unlinked.

        Returns:
        True if the field has been unlinked, otherwise false.

        Example:

        Shows how to unlink specific field.
        Document doc = new Document(getMyDir() + "Linked fields.docx");
        doc.getRange().getFields().get(1).unlink();
      • update

        public void update()
                   throws java.lang.Exception
        Performs the field update. Throws if the field is being updated already.

        Example:

        Shows how to insert a field into a document using FieldType.
        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);

        // In some cases, updating fields could be computationally expensive, and it may be a good idea to defer the update.
        // Not all field types require updating, exceptions include BARCODE and MERGEFIELD.
        doc.getBuiltInDocumentProperties().setAuthor("John Doe");
        builder.write("This document was written by ");
        builder.insertField(FieldType.FIELD_AUTHOR, updateInsertedFieldsImmediately);

      • update

        public void update(boolean ignoreMergeFormat)
                   throws java.lang.Exception
        Performs a field update. Throws if the field is being updated already.
        Parameters:
        ignoreMergeFormat - If true then direct field result formatting is abandoned, regardless of the MERGEFORMAT switch, otherwise normal update is performed.

        Example:

        Shows a way to update a field ignoring the MERGEFORMAT switch.
        LoadOptions loadOptions = new LoadOptions();
        {
            loadOptions.setPreserveIncludePictureField(true);
        }
        Document doc = new Document(getMyDir() + "Field sample - INCLUDEPICTURE.docx", loadOptions);
        
        for (Field field : doc.getRange().getFields()) {
            if (((field.getType()) == (FieldType.FIELD_INCLUDE_PICTURE))) {
