Interface TreeNode

All Known Subinterfaces:: DataNode, WorkspaceNode

All Known Implementing Classes:: AbstractNode, WorkspaceNodeImpl

public interface TreeNode

Represents a node in the tree. Has a relative name and a Fqn. Maintains a hashmap. If the node is created in a replicated cache, the relative and fully qualified name, and the keys and values of the hashmap have to be serializable.

Note that current version supports different levels of transaction locking such as simple locking (TreeCache.SERIALIZABLE, or R/W lock with upgrade ( 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.

This class is not synchronized, so access to instances of TreeNode need to be run under an isolation level > NONE.
