Cache and reuse NIO memory mapped buffers
-----------------------------------------
Key: GEOT-3275
URL: http://jira.codehaus.org/browse/GEOT-3275
Project: GeoTools
Issue Type: Improvement
Components: data shapefile
Affects Versions: 2.7-M3
Reporter: Andrea Aime
Assignee: Andrea Aime
Fix For: 2.7-M4
NIO memory mapped buffers are not meant to be opened and closed repeatedly, but
meant to be used for a long time instead.
Also, they can be created, and then a child for each thread can be used to just
hold the state (position) of the read.
There is a downside on Windows though: a careless developer not disposing the
shapefiles will have the files locked. So roll out a separate option to enable
this kind of caching
