Example 40 with DeleteEdit

use of org.eclipse.text.edits.DeleteEdit in project flux by eclipse.

the class Utils method getOffsetAdjustment.

public static int getOffsetAdjustment(TextEdit edit, final int offset) {
    final int[] holder = new int[] { 0 };
    edit.accept(new TextEditVisitor() {

        @Override
        public boolean visit(DeleteEdit edit) {
            if (offset >= edit.getOffset()) {
                holder[0] -= edit.getLength();
            }
            return super.visit(edit);
        }

        @Override
        public boolean visit(InsertEdit edit) {
            if (offset >= edit.getOffset()) {
                holder[0] += edit.getText().length();
            }
            return super.visit(edit);
        }

        @Override

                holder[0] += edit.getText().length() - edit.getLength();
            }
            return super.visit(edit);
