Prepare jBPM-BPEL for performance-enhancing laziness changes in upcoming Jaxen-1.1.3 ------------------------------------------------------------------------------------ Key: BPEL-313 URL: https://jira.jboss.org/jira/browse/BPEL-313 Project: jBPM BPEL Issue Type: Patch Security Level: Public (Everyone can see) Components: Engine Reporter: Aleksander Adamowski Assignee: Alejandro Guizar Priority: Minor There's a change coming up in Jaxen that has the potential to significantly increase its performance by making returned lists lazy: http://jira.codehaus.org/browse/JAXEN-31 However, to take advantage of this performance-enhancing laziness, one has to employ special techniques when using Jaxen's APIs - most notably, avoid calling size() on Jaxen-returned node lists or sorting them - where possible, using isEmpty(), iterators, and get(). I'm doing proof of concept work on jBPM-BPEL sources right now. The progress can be tracked on GitHub in the jbpm-bpel project on the perf-jaxen-laziness branch: http://github.com/aadamowski/jbpm-bpel/commits/perf-jaxen-laziness Over there there's currently an untested commit there that demonstrates the aforementioned techniques: http://github.com/aadamowski/jbpm-bpel/commit/6feb2d1a0434e73e47f57e2151b... -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
