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}")

}
