Title: RE: a performance issue
Sandy,
The answer to 1) is no check needs to be made, because ArrayIndexOutOfBoundsException is a RuntimeException, and will be thrown by the VM if an incorrect subscript is referenced.
My comment to 2) (and the whole problem in general), (with the one caveat
Hello,
i've one problem with the Xerces Parser. After parsing a XML document all

Is there any way to disabled it or any method to convert it back?
The problem is when i try to put some text in this format , then

Hi Tom & Brad,
Thanks for your reply. Though what you mentioned (loop iterations) is not
exactly the case I'm worrying, it definitely helps me understanding the
problem clearly.
Consider a method (from org.apache.xerces.utils.StringPool):
private boolean ensureCapacity(int chunk, int index) {

Title: RE: a performance issue
My guess is because of something very interesting I recently found in some parsing I was doing:
Looping through an array is FASTER in a while-loop with a termination condition of boolean (true), where the ArrayOutOfBoundsException is handled, than it is in a fo
Hi all,
In many classes, to detect the need of array-resizing, we try to access a
specific position, and do the resizing when
"ArrayIndexOutOfBoundsException" is caught (or NullPointerException for
multidimensional arrays).
But my understanding is that throw-catch exceptions is much more expensi

Hi. This bug was fixed a week ago. I tried your program and xml files, no
error was reported on "test2.xml". If you get the latest code from CVS,
hopefully, the problem would disappear. Feel free to contact me if you
still have difficulties with ID/IDREF.
