[jira] [Created] (CAY-1675) [PATCH] add .first(List) method to
Expression to enhance in-memory filtering
[PATCH] add .first(List<T>) method to Expression to enhance in-memory filtering
-------------------------------------------------------------------------------
Key: CAY-1675
URL: https://issues.apache.org/jira/browse/CAY-1675
Project: Cayenne
Issue Type: Improvement
Components: Core Library
Affects Versions: 3.1M4
Reporter: John Huss
Priority: Trivial
Attachments: expression_first_match_patch.txt
Add .first(List<T>) method to Expression to enhance in-memory filtering. This is a very helpful convenience making one-liners possible where an expression is known to return a single result (like filtering on a unique key). Patch attached.

[jira] [Commented] (CAY-1675) [PATCH] add .first(List) method to
Expression to enhance in-memory filtering

Andrus Adamchik commented on CAY-1675:
--------------------------------------
+1. Although we need a more efficient implementation ... there's no need to do call filterObjects, to return just the first object in the list and throw away the rest. I can take care of this change, which is pretty trivial.
