Subject [jira] [Created] (DERBY-5755) Minor cleanup of DataDictionaryImpl.getRoutineList()
Date Thu, 10 May 2012 12:21:48 GMT
Knut Anders Hatlen created DERBY-5755:

             Summary: Minor cleanup of DataDictionaryImpl.getRoutineList()
                 Key: DERBY-5755
                 URL: https://issues.apache.org/jira/browse/DERBY-5755
             Project: Derby
          Issue Type: Improvement
          Components: SQL
    Affects Versions:
            Reporter: Knut Anders Hatlen
            Assignee: Knut Anders Hatlen
            Priority: Trivial

I noticed two small possibilities for improvement in DataDictionaryImpl.getRoutineList() when
I worked on DERBY-5730:

- The method always returns a list of one or zero items. Instead of creating an ArrayList,
it should use Collections.singletonList() and Collections.EMPTY_LIST, which are more memory-efficient.

- It loops through the entire SYSFUN_FUNCTIONS array, even if the matching function is found
in the first cell of the array. It should break out of the loop once a match is found.
