Subject [jira] Created: (JCR-2744) Avoid element arrays in PathImpl
Date Thu, 09 Sep 2010 15:23:32 GMT
Avoid element arrays in PathImpl
--------------------------------

                 Key: JCR-2744
                 URL: https://issues.apache.org/jira/browse/JCR-2744
             Project: Jackrabbit Content Repository
          Issue Type: Improvement
          Components: jackrabbit-spi, jackrabbit-spi-commons
            Reporter: Jukka Zitting


The path handling code in spi-commons shows quite often in thread dumps and profiling results,
as the current implementation does quite a bit of repetitive allocating and copying of path
element arrays. We should be able to streamline and simplify the path handling code by only
tracking the latest path element and a reference to the parent path. To do this efficiently
we may need to adjust some of the Path and PathFactory method declarations (that currently
assume element array -based paths) also in the SPI.
