[platform-ant-dev] FastPartitioner
|
Dear eclipse-ant team!
we have implemented an optimized version of DefaultPartitioner that
caches the positions tracking the partitions, avoiding an array creation
every time the document is asked for the positions. For clients that
only instantiate DefaultPartitioner or subclass it in a way that does
not modify the positions, the new FastPartitioner can be used as
replacement for DefaultPartitioner without further modification.
I have included a patch that does that replacement in the ant.ui plug-in
project.
Happy partitioning,
tom
