Problem

“I have nearly 500 reports, each report having logo on the right up corner in all tabs, in a cell having formula “boimg://logo.bmp” and read as image URL. Now i have come up with change in logo format. Now the same formula is to be changed to “boimg://logo.jpg””.

Code

private static int replaceExpression(DocumentInstance widoc, String from, String to) {
   ReportDictionary reportDictionary = widoc.getDictionary();
   ArrayList nodes = getListOfTreeNodes(widoc.getStructure(), false);
   int n = 0;
   for (TreeNode node : nodes) {
      if (node instanceof ReportCell) {
         ReportCell reportCell = (ReportCell)node;
         ReportExpression reportExpression = reportCell.getExpr();
         if (reportExpression instanceof FormulaExpression) {
            FormulaExpression formulaExpression = (FormulaExpression)reportExpression;
            if (formulaExpression.getValue().compareTo(from) == 0){
               FormulaExpression newFormulaExpression = reportDictionary.createFormula(to);
               reportCell.setExpr(newFormulaExpression);
               n += 1;
            }
         }
      }
   }
   widoc.applyFormat();
   return n;
}

public static ArrayList getListOfTreeNodes(TreeNode root, boolean onlyLeaves) {
   ArrayList nodes = new ArrayList();
   treeNodeTraversal(root, nodes, onlyLeaves);
   return nodes;
}

private static void treeNodeTraversal(TreeNode node, ArrayList nodes, boolean onlyLeaves) {
   if (!onlyLeaves || node.isLeaf()) {
      nodes.add(node);
   }
   for (int i = 0; i < node.getChildCount(); ++i) {
      treeNodeTraversal(node.getChildAt(i), nodes, onlyLeaves);
   }
}
