public class SimDistribStateManager
extends Object
implements DistribStateManager

Simulated DistribStateManager that keeps all data locally in a static structure. Instances of this class are identified by their id in order to simulate the deletion of ephemeral nodes when close() is invoked.

SimDistribStateManager

public SimDistribStateManager()

Deprecated.

SimDistribStateManager

public SimDistribStateManager(SimDistribStateManager.Node root)

Deprecated.

Construct new state manager that uses provided root node for storing data.

Parameters:

root - if null then a new root node will be created.

SimDistribStateManager

public SimDistribStateManager(ActionThrottle actionThrottle,
                              ActionError actionError)

Deprecated.

SimDistribStateManager

public SimDistribStateManager(SimDistribStateManager.Node root,
                              ActionThrottle actionThrottle,
                              ActionError actionError)

Deprecated.

createNewRootNode

public static SimDistribStateManager.Node createNewRootNode()

Deprecated.

copyFrom

public void copyFrom(DistribStateManager other,
                     boolean failOnExists)
              throws InterruptedException,
                     IOException,
                     org.apache.zookeeper.KeeperException,
                     AlreadyExistsException,
                     BadVersionException

Deprecated.

Copy all content from another DistribStateManager.

Parameters:

other - another state manager.

failOnExists - abort copy when one or more paths already exist (the state of this manager remains unchanged).

Throws:

InterruptedException

IOException

org.apache.zookeeper.KeeperException

AlreadyExistsException

BadVersionException

withEphemeralId

public SimDistribStateManager withEphemeralId(String id)

Deprecated.

Create a copy of this instance using a specified ephemeral owner id. This is useful when performing node operations that require using a specific id. Note: this instance should never be closed, it can be just discarded after use.

Parameters:

id - ephemeral owner id

getRoot

public SimDistribStateManager.Node getRoot()

Deprecated.

Get the root node of the tree used by this instance. It could be a static shared root node.

clear
