--------------------------------
Summary: Minor performance improvements
Key: BVAL-113
URL: https://issues.apache.org/jira/browse/BVAL-113
Project: BVal
Issue Type: Improvement
Components: jsr303
Affects Versions: 0.4, 0.5
Reporter: Jarek Gawor
We found a couple of minor performance issues that came up during our
profiling:
1) AnnotationProcessor.java, FeaturesCapable.java, and MetaBean.java use
ArrayUtils.add() to grow the array. The issue is that ArrayUtils.add() uses
reflection to grown the array which 1) is slower then just instantiating the
array, and 2) is completely unnecessary in these cases as the type of the array
is always well known and doesn't change.
2) MetaBean.java stores MetaProperty objects in a sorted array and uses binary
search to lookup and insert them. An implementation that stores these objects
in a map would offer faster lookup and insert performance.
