/* lo.h: LEAF OBJECT POOL CLASS INTERFACE

|
*
|
|
* The Leaf Object PoolClass is an automatically managed (ie garbage
|
|
* collected) pool for managing "leaf" objects. Leaf objects are
|
|
* objects that have no references or no references that need tracing
|
|
* (ie the objects they refer too are non-moving and are manually
|
|
* managed).
|
|
*
|
|
* This Class has the following features:
|
|
*
|
|
* Approximately 6% (asymptotically) space overhead on managed objects.
|
|
*
|
|
* Automatically reclaims memory used by objects no longer reachable
|
|
* from the roots.
|
|
*
|
|
* Non-moving. References to objects in this pool will never change
|
|
* due to "fixing".
|
|
*
|
|
* Buffers will always "commit". When allocating using a buffer,
|
|
* commit will never fail.
|
|
*
|
|
* The following caveat applies:
|
|
*
|
|
* Space and time performance will degrade when fragmentation
|
|
* increases.
