Interface CommitContext

All Known Implementing Classes:

public interface CommitContext

A CommitContext instance can be obtained from CommitInfo.getInfo() if it has been set before the merge call. This can then be used by CommitHook to record some metadata regarding the commit.

CommitContext state would be reset in case commit is retried from within NodeStore say when a merge exception occurs.
