Field Detail

log

protected static org.apache.commons.logging.Log log

Debug log.

trace

protected static final boolean trace

lock_

protected transient IdentityLock lock_

Lock manager that manages locks to be acquired when accessing the node inside a transaction. Lazy set just in case locking is not needed.

delegate

protected NodeSPI delegate

Constructor Detail

UnversionedNode

public UnversionedNode()

Constructs a new node with an FQN of Root.

UnversionedNode

protected UnversionedNode(Object child_name,
                          Fqn fqn,
                          Map data,
                          boolean mapSafe,
                          CacheSPI cache)

Constructs a new node with a name, etc.

Parameters:

mapSafe - true if param data can safely be directly assigned to this object's data field; false if param data's contents should be copied into this object's data field.
