Class FieldMergeRec

public class FieldMergeRec 
extends Field

Implements the MERGEREC field.
At the moment the MERGEREC and MERGESEQ fields implement the same functionality because we don't know for sure how to skip records in Aspose.Words mail merge.

Example:

Shows how to number and count mail merge records in the output documents of a mail merge using MERGEREC and MERGESEQ fields.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Use a document builder to insert a merge field
builder.write("Dear ");
FieldMergeField fieldMergeField = (FieldMergeField) builder.insertField(FieldType.FIELD_MERGE_FIELD, true);
fieldMergeField.setFieldName("Name");
builder.writeln(",");

// A MERGEREC field will print the row number of the data being merged
builder.write("\nRow number of record in data source: ");
FieldMergeRec fieldMergeRec = (FieldMergeRec) builder.insertField(FieldType.FIELD_MERGE_REC, true);

Assert.assertEquals(fieldMergeRec.getFieldCode(), " MERGEREC ");

// A MERGESEQ field will count the number of successful merges and print the current value on each respective page
// If no rows are skipped and the data source is not sorted, and no SKIP/SKIPIF/NEXT/NEXTIF fields are invoked,
// the MERGESEQ and MERGEREC fields will function the same
builder.write("\nSuccessful merge number: ");
FieldMergeSeq fieldMergeSeq = (FieldMergeSeq) builder.insertField(FieldType.FIELD_MERGE_SEQ, true);

Assert.assertEquals(fieldMergeSeq.getFieldCode(), " MERGESEQ ");

// Insert a SKIPIF field, which will skip a merge if the name is "John Doe"
FieldSkipIf fieldSkipIf = (FieldSkipIf) builder.insertField(FieldType.FIELD_SKIP_IF, true);
builder.moveTo(fieldSkipIf.getSeparator());
fieldMergeField = (FieldMergeField) builder.insertField(FieldType.FIELD_MERGE_FIELD, true);
fieldMergeField.setFieldName("Name");
fieldSkipIf.setLeftExpression("=");
fieldSkipIf.setRightExpression("John Doe");

// Create a data source with 3 rows, one of them having "John Doe" as a value for the "Name" column
// Since a SKIPIF field will be triggered once by that value, the output of our mail merge will have 2 pages instead of 3
// On page 1, the MERGESEQ and MERGEREC fields will both display "1"
// On page 2, the MERGEREC field will display "3" and the MERGESEQ field will display "2"
DataTable table = createTable("Employees", new String[]{"Name"},
        new String[][]{{"Jane Doe"}, {"John Doe"}, {"Joe Bloggs"}});

// Execute mail merge and save document
doc.getMailMerge().execute(table);
doc.save(getArtifactsDir() + "Field.MERGEREC.MERGESEQ.docx");

void
isDirty(booleanvalue)
           Gets or sets whether the current result of the field is no longer correct (stale) due to other modifications made to the document.
booleanisLocked()
void
isLocked(booleanvalue)
           Gets or sets whether the field is locked (should not recalculate its result).
intgetLocaleId()
void
setLocaleId(intvalue)
           Gets or sets the LCID of the field.
java.lang.StringgetResult()
void
setResult(java.lang.Stringvalue)

Method Summary
java.lang.StringgetFieldCode()
Returns text between field start and field separator (or field end if there is no separator). Both field code and field result of child fields are included.
java.lang.StringgetFieldCode(boolean includeChildFieldCodes)
Returns text between field start and field separator (or field end if there is no separator).
Noderemove()
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.
booleanunlink()
Performs the field unlink.
voidupdate()
Performs the field update. Throws if the field is being updated already.
voidupdate(boolean ignoreMergeFormat)
Performs a field update. Throws if the field is being updated already.

    • Method Detail

      • getFieldCode

        public java.lang.String getFieldCode()
        Returns text between field start and field separator (or field end if there is no separator). Both field code and field result of child fields are included.

        Example:

        Inserts a field into a document using DocumentBuilder and FieldCode.
        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);
        
        // Insert a simple Date field into the document.
        // When we insert a field through the DocumentBuilder class we can get the
        // special Field object which contains information about the field.
        Field dateField = builder.insertField("DATE \\* MERGEFORMAT");
        
        // Update this particular field in the document so we can get the FieldResult.
        dateField.update();
        
        // Display some information from this field.
        // The field result is where the last evaluated value is stored. This is what is displayed in the document
        // When field codes are not showing.
        System.out.println(MessageFormat.format("FieldResult: {0}", dateField.getResult()));

        // The field type defines what type of field in the Document this is. In this case the type is "FieldDate"
        System.out.println(MessageFormat.format("FieldType: {0}", dateField.getType()));
        
        // Finally let's completely remove the field from the document. This can easily be done by invoking the Remove method on the object.
        dateField.remove();

        Example:

        Shows how to get text between field start and field separator (or field end if there is no separator)
        Document doc = new Document(getMyDir() + "Field.FieldCode.docx");

      • getFieldCode

        public java.lang.String getFieldCode(boolean includeChildFieldCodes)
        Returns text between field start and field separator (or field end if there is no separator).
        Parameters:
        includeChildFieldCodes - True if child field codes should be included.

        Example:

        Shows how to get text between field start and field separator (or field end if there is no separator)

      • 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.

      • unlink

        public boolean unlink()

        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:

      • update

        public void update()

      • 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();
