Groovy UNO Extension

Overview

Getting Started

Usage

The best way to explain the differences between the Java UNO API's and using Groovy with and without the extension is with some example code. A lot of the examples are from SCalc.java that is included with the AOO SDK.
Leaving out try/catch for brevity and assumes we have a reference to XSpreadsheetDocument myDoc..

Get the first sheet in the spreadsheet document and insert data into a cell

Java way

   XSpreadsheets xSheets = myDoc.getSheets() ;
   XIndexAccess oIndexSheets = (XIndexAccess) UnoRuntime.queryInterface(
       XIndexAccess.class, xSheets);
   xSheet = (XSpreadsheet) UnoRuntime.queryInterface(
      XSpreadsheet.class, oIndexSheets.getByIndex(0));
   xCell = xSheet.getCellByPosition(1,0);
   xCell.setFormula("Sample");

Groovy Extension way

   XSpreadsheet xSheet = myDoc.getSheetByIndex(0)
   xSheet.setTextToCell(1,0,"Sample")

Using Groovy without the extension allows removing the Interface cast on the right side and not using semi-colons.
The following examples are in that style and other than that, similar to the Java way.

Setting the Cell Style property The extension adds a setter method for CellStyle allowing what looks like property access to cellStyle. ToDo add getter method
Without Extension

  XPropertySet xCellProps = UnoRuntime.queryInterface(XPropertySet.class, xCell)
  xCellProps.setPropertyValue("CellStyle", "Result")

With extension

  xCell.cellStyle = "Result"

Using Enum Types The extension adds getter and setter methods for CellVertJustify allowing what looks like property access to vertJustify.
Without extension

   xCellProps.setPropertyValue("VertJustify", com.sun.star.table.CellVertJustify.TOP)

With extension

   xCell.vertJustify = com.sun.star.table.CellVertJustify.TOP

Setting the active sheet Without Extension but using SpreadsheetDocHelper.groovy included with the OpenOfficeGradleIntegration aoo-client template.

   XModel xSpreadsheetModel = sdHelper.getModel()
   XController xSpreadsheetController = xSpreadsheetModel.getCurrentController()
   XSpreadsheetView xSpreadsheetView = UnoRuntime.queryInterface(XSpreadsheetView.class, xSpreadsheetController)
   xSpreadsheetView.setActiveSheet(xSpreadsheet)

With extension and a SpreadsheetDocHelper.groovy method to get the XSpreadsheetView directly

   XSpreadsheetView xSpreadsheetView = sdHelper.getSpreadsheetView()
   xSpreadsheetView.setActiveSheet(xSpreadsheet)

Get cell ranges Without extension

   XCellRangesQuery xCellQuery = UnoRuntime.queryInterface(XCellRangesQuery.class, xSpreadsheet)
   XSheetCellRanges xFormulaCells = xCellQuery.queryContentCells((short)CellFlags.FORMULA)

With extension

   XSheetCellRanges xFormulaCells = xSpreadsheet.getCellRanges(CellFlags.FORMULA)

Use of XEnumerationAccess Without extension

   XEnumerationAccess xFormulas = xFormulaCells.getCells()
   XEnumeration xFormulaEnum = xFormulas.createEnumeration()
   while (xFormulaEnum.hasMoreElements()) {
       Object formulaCell = xFormulaEnum.nextElement()

       xCell = UnoRuntime.queryInterface(XCell.class, formulaCell)
       XCellAddressable xCellAddress = UnoRuntime.queryInterface(XCellAddressable.class, xCell)
       println("Formula cell in column " +
           xCellAddress.getCellAddress().Column + ", row " + xCellAddress.getCellAddress().Row
           + " contains " + xCell.getFormula())
       }

With extension

   XCell[] cellList = xFormulaCells.cellList
   cellList.each() {println("Formula cell in column ${it.address.Column}, " + 
       "row ${it.address.Row} contains ${it.formula}")
   }

Create a new cell range container Without Extension

   com.sun.star.lang.XMultiServiceFactory xDocFactory = UnoRuntime.queryInterface(
       com.sun.star.lang.XMultiServiceFactory.class, xSpreadsheetDocument)
   com.sun.star.sheet.XSheetCellRangeContainer xRangeCont = UnoRuntime.queryInterface(
       com.sun.star.sheet.XSheetCellRangeContainer.class,
       xDocFactory.createInstance("com.sun.star.sheet.SheetCellRanges"));

with extension

   XSheetCellRangeContainer xRangeCont = xSpreadsheetDocument.rangeContainer

Query the list of filled cells from a range container Without Extension print("All filled cells: ")

   com.sun.star.container.XEnumerationAccess xCellsEA = xRangeCont.getCells()
   com.sun.star.container.XEnumeration xEnum = xCellsEA.createEnumeration()          
   while (xEnum.hasMoreElements()) {
       Object aCellObj = xEnum.nextElement()
       com.sun.star.sheet.XCellAddressable xAddr = UnoRuntime.queryInterface(
           com.sun.star.sheet.XCellAddressable.class, aCellObj)
       com.sun.star.table.CellAddress aAddr = xAddr.getCellAddress()
       println(sdHelper.getCellAddressString(aAddr.Column, aAddr.Row) + " ")
   }

with extension

// example for using a closure to iterate through list of cells XCell[] cellList2 = xRangeCont.cellList print("All filled cells: ") cellList2.each() {println("Formula cell in column ${it.address.Column}, " +

   "row ${it.address.Row} contains ${it.formula}")

}
