Description copied from interface: StateTransferManager

Writes the state for the portion of the tree named by fqn to the provided OutputStream.

Specified by:

getState in interface StateTransferManager

Overrides:

getState in class DefaultStateTransferManager

Parameters:

out - stream to write state to

fqn - Fqn indicating the uppermost node in the portion of the tree whose state should be returned.

timeout - max number of millis this method should wait to acquire any locks, if necessary, on the nodes being transferred

force - if locks are needed and cannot be acquired after timeout millis, should the lock acquisition be forced, and any existing transactions holding locks on the nodes be rolled back?

suppressErrors - if true, all exceptions are logged but not propagated.

Throws:

Exception - in event of error

setState

protected void setState(ObjectInputStream state,
            NodeSPI targetRoot)
                 throws Exception

Deprecated.

Set the portion of the cache rooted in targetRoot to match the given state. Updates the contents of targetRoot to reflect those in new_state.

NOTE: This method performs no locking of nodes; it is up to the caller to lock targetRoot before calling this method.

Overrides:

setState in class DefaultStateTransferManager

Parameters:

state - a serialized byte[][] array where element 0 is the transient state (or null) , and element 1 is the persistent state (or null)

targetRoot - node into which the state should be integrated

Throws:

Exception

acquireLocksForStateTransfer

protected void acquireLocksForStateTransfer(NodeSPI root,
                                long timeout,
                                boolean force)
                                     throws InterruptedException

Deprecated.

Throws:

InterruptedException

releaseStateTransferLocks

protected void releaseStateTransferLocks(NodeSPI root)

Deprecated.
