Method Detail

shareFreeListback to summary
public void shareFreeList(BlockRevQueue q)

Overrides org.eclipse.jgit.revwalk.Generator.shareFreeList.

Reconfigure this queue to share the same free list as another.

Multiple revision queues can be connected to the same free list, making it less expensive for applications to shuttle commits between them. This method arranges for the receiver to take from / return to the same free list as the supplied queue.

Free lists are not thread-safe. Applications must ensure that all queues sharing the same free list are doing so from only a single thread.

Parameters
q:BlockRevQueue

another FIFO queue that wants to share our queue's free list.
