StyleNode objects could be much more lightweight
------------------------------------------------
Key: TRINIDAD-633
URL: https://issues.apache.org/jira/browse/TRINIDAD-633
Project: MyFaces Trinidad
Issue Type: Improvement
Reporter: Adam Winer
We create a lot of StyleNode objects ( > 5000 in one test I ran recently), so
anything that
can be done to make these objects less heavy is a good thing.
A couple things could be done:
- Use singletonList() instead of unmodifiableList() around Arrays.asList() for
single-element arrays
- Check the incoming arrays not just against null, but also against being
zero-element arrays,
and use Collections.emptyList() as necessary there
(SkinStyleSheetParserUtils, in particular, is passing in empty lists for
includedStyles
and empty sets for inhibitedProperties.)
The former optimization saves 76 bytes every time it happens, the latter 84
bytes
every time it happens. This can add up to a good bit of saved memory.
