Examples of org.jboss.as.clustering.lock.SharedLocalYieldingClusterLockManager

org.jboss.as.clustering.lock.SharedLocalYieldingClusterLockManager
Distributed lock manager intended for use cases where multiple local threads can share the lock, but only one node in the cluster can have threads using the lock. Nodes holding the lock yield it to remote requestors if no local threads are using it; otherwise remote requestors block.
The expected use case for this class is controlling access to resources that are typically only accessed on a single node (e.g. web sessions or stateful session beans), with the distributed lock used primarily to guarantee that.
