Class ListenerTest

java.lang.Object

cq.CQEventTest

cq.ListenerTest

public class ListenerTest
extends CQEventTest

A Hydra test that concurrently performs a number of entry operations while adding and removing CQ listeners. Verifies CQListeners are invoked when expected and in the correct order.

Since:

5.2

Method Detail

HydraTask_initialize

public static void HydraTask_initialize()
                                 throws com.gemstone.gemfire.cache.query.CqClosedException,
                                        com.gemstone.gemfire.cache.query.RegionNotFoundException

Creates and initializes the singleton instance of ListenerTest in this VM.

Throws:

com.gemstone.gemfire.cache.query.CqClosedException

com.gemstone.gemfire.cache.query.RegionNotFoundException

HydraTask_exerciseListeners

public static void HydraTask_exerciseListeners()

HydraTask method to perform listener operations (add, remove, set, init), stores the expected list of listeners to be invoked in the BB and then performs a random entry operation. Listeners add their name to the InvokedListener List in the BB when invoked. In serialExecution mode, the two listener lists are then compared to ensure that the listeners were invoked in the expected order.

exerciseListeners

protected void exerciseListeners()

see HydraTask_exerciseListeners

getNumCqListeners

protected int getNumCqListeners()

getListenerOp

protected int getListenerOp()

Return a random operation to perform on the cacheListenerList.

getNewListener

protected com.gemstone.gemfire.cache.query.CqListener getNewListener()

Returns a new instance of MultiListener

addListener

protected void addListener(com.gemstone.gemfire.cache.query.CqQuery cq)

Adds a listener to the existing listener list

removeListener

protected void removeListener(com.gemstone.gemfire.cache.query.CqQuery cq)

Removes a listener from the existing listener list

initListener

protected void initListener(com.gemstone.gemfire.cache.query.CqQuery cq)

Initializes the listener list with ListenerPrms.maxListeners entries

writeExpectedListenerListToBB

protected void writeExpectedListenerListToBB(com.gemstone.gemfire.cache.query.CqQuery cq)

Writes the listener lists for the given cq out to the BB

See Also:

ListenerBB.ExpectedListeners

compareListenerLists

protected void compareListenerLists(com.gemstone.gemfire.cache.query.CqQuery cq)

Compares the Expected and Invoked Listener Lists in ListenerBB for the given CQ

See Also:

ListenerBB.ExpectedListeners, ListenerBB.InvokedListeners

getCqListenerNames

protected String getCqListenerNames(com.gemstone.gemfire.cache.query.CqQuery cq)

Utility method to get a string containing the names of the listeners (separated by ":") for the given region.

clearInvokedListenerList

protected void clearInvokedListenerList(com.gemstone.gemfire.cache.query.CqQuery cq)

Clears the InvokedListener list in the BB (for the given CQ)
