java.lang.Objectorg.objectweb.jonathan.resources.lib.JChunkFactory
A Chunk Factory implementation.
A chunk factory creates and manages chunks. This chunk factory manages two pools of chunks of different sizes, so that a released chunk may be reused in a different context, saving the time for allocating and collecting the associated memory. The sizes of the chunks used, and of the preallocated pools may be changed.
