Gary Gregory updated XALANJ-2581:
---------------------------------
Description:
Minor performance improvement:
- Use String.lastIndexOf(int) instead of String.lastIndexOf(String).
- Use the char version of StringBuffer.append() and String.indexOf().
- Make ObjectFactory classes final.
- Eliminate call to inefficient String(String) constructor.
- Eliminate creation of temporary strings in loops.
- Iterate over the entries a the map instead of the keys. This avoids a
redundant table lookup for each value.
- String.length() == 0 tends to be slightly faster than String.equals("").
