RepositoryLock

com.atlassian.stash.concurrent.RepositoryLock

Class Overview

A reusable component for locking a repository while an operation is performed.

Separate instances of this interface are not related. Locking a repository in one instance does not lock it in any other. The intention is to allow grouping operations that perform similar processing, or rely on the same repository data, so that only one is running on a given repository at a time, using multiple locks when different bands of processing can be performed concurrently.

Note: When used by plugin developers, no instance of this lock can ever prevent the host application from performing any of its own processing on any aspect of a repository.
