Examples of org.jboss.cache.TreeNode

org.jboss.cache.TreeNode
Represents a node in the tree. Has a relative name and a Fqn. Maintains a hashmap of general data. If the node is created in a replicated cache, the relative and fully qualified name, and the keys and values of the hashmap must be serializable.
The current version supports different levels of transaction locking such as simple locking ( {@link org.jboss.cache.lock.IsolationLevel#SERIALIZABLE}, or Read/Write lock with upgrade ( {@link org.jboss.cache.lock.IsolationLevel#REPEATABLE_READ}) --that is the read lock will be automatically upgraded to write lock when the same owner intends to modify the data after read.
Implementations may not necessarily be not synchronized, so access to instances of TreeNode need to be run under an isolation level above NONE. @author Bela Ban March 25 2003 @author Ben Wang @author Manik Surtani (manik@jboss.org) @version $Revision: 2058 $
