[jbpm-issues] [JBoss JIRA] Created: (JBPM-2625) Add count() to Queries to support pagination

Add count() to Queries to support pagination -------------------------------------------- Key: JBPM-2625 URL: https://jira.jboss.org/jira/browse/JBPM-2625 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.x Reporter: Peter Horvath Queries provide a powerful interface to access JBPM tasks, jobs, deployments, etc; currently the only way you can get the number of results that match a filter is to load the whole list, and determine its size by calling .size() method - this is extremely inefficient and can even cause OutOfMemoryError (e.g. a HistoryActivityInstanceQuery could return tens of thousands elements) count() could be used with page(int firstResult, int maxResults) method to create a paginated result list where you can display the number of pages -- 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
