Examples of org.jboss.cache.NodeSPI.markForUpdate()

org.jboss.cache.NodeSPI.markForUpdate()
Marks a node for updating. Internally, this creates a copy of the delegate and performs any checks necessary to maintain isolation level.
Only used with MVCC. @param container data container @param writeSkewCheck if true, and the node supports write skew checking, nodes are tested for write skews.
