Avoid LiteShape2 geometry cloning when the datastore declares the feature can
be altered at leisure
---------------------------------------------------------------------------------------------------
Key: GEOT-1467
URL: http://jira.codehaus.org/browse/GEOT-1467
Project: GeoTools
Issue Type: Bug
Components: core main, core render
Affects Versions: 2.4-RC0
Reporter: Andrea Aime
Assignee: Andrea Aime
Fix For: 2.4-RC1, 2.5-M0
LiteShape2 has geometry cloning to protect the datastore from being altered
when the geometry gets decimated and transformed (this operation occurs in
place). This is not necessary most of the time, and is a significant overhead
when the geometry is big. Of course, if the geometry is not based on
LiteCoordinateSequence objects, cloning will occurr anyways because we need
that kind of coordinate sequence, but that's another matter.
To support this, a new hint, FEATURE_DETACHED, has been added, and I'll make
sure all JDCB datastores as well as the shapefile datastore
declare to implement it.
