-----------------------------------------
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: 10.9.0.0
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.
