> Implement IgniteReentrantLock data structure
> --------------------------------------------
>
> Key: IGNITE-642
> URL: https://issues.apache.org/jira/browse/IGNITE-642
> Project: Ignite
> Issue Type: Sub-task
> Components: data structures
> Affects Versions: 1.6
> Reporter: Dmitriy Setrakyan
> Assignee: Vladisav Jelisavcic
> Labels: features
> Fix For: 1.6
>
>
> We need to add {{IgniteReentrantLock}} data structure in addition to other
> data structures provided by Ignite. {{IgniteReentrantLock}} should have
> similar API to {{java.util.concurrent.locks.ReentrantLock}} class in JDK.
> As an example, you can see how
> [IgniteCountDownLatch|https://github.com/apache/incubator-ignite/blob/master/modules/core/src/main/java/org/apache/ignite/IgniteCountDownLatch.java]
> is implemented in
> [GridCacheCountDownLatchImpl|https://github.com/apache/incubator-ignite/blob/master/modules/core/src/main/java/org/apache/ignite/internal/processors/datastructures/GridCacheCountDownLatchImpl.java]
> class.
> In general we need to have an entity in ATOMIC cache storing lock-owner
> identifier together with a queue of waiters.
