Method Detail

HydraTask_initializeLocator

public static void HydraTask_initializeLocator()

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

HydraTask_initializeClient

public static void HydraTask_initializeClient()

Creates and initializes the singleton instance of LeadSelectionTest in this VM and initializes a region.

HydraTask_serialLeadSelectionTest

public static void HydraTask_serialLeadSelectionTest()

Hydra task for serial lead selection test.

HydraTask_concLeadSelectionTest

public static void HydraTask_concLeadSelectionTest()

Hydra task for concurrent lead selection test.

waitForChange

protected Object[] waitForChange(com.gemstone.gemfire.distributed.DistributedMember member,
                                 int msToSleep)

Given a member, wait for the lead member to become different than the given member.

Specified by:

waitForChange in class SelectionTest

Parameters:

member - A distributed member or null. This method waits until the current lead member is different than this one.

msToSleep - The number of millis to sleep between checks for the lead member.

Returns:

[0] (Long) The number of millseconds it took to detect a lead change. Note that the value of msToSleep can affect this value. [1] (DistributedMember) The new DistributedMember

getNumToStop

protected int getNumToStop()

Return the number of client members in this test as we want to stop them all.

Specified by:

getNumToStop in class SelectionTest

serialVerifyAfterStop

protected void serialVerifyAfterStop(com.gemstone.gemfire.distributed.DistributedMember currentLead,
                                     int totalNumStopped)

In a serial test, do verification after stopping a lead member.

Specified by:

serialVerifyAfterStop in class SelectionTest

Parameters:

currentLead - The current lead member.

totalNumStopped - The total number of members stopped (and not yet restarted).

getCurrentMember

protected com.gemstone.gemfire.distributed.DistributedMember getCurrentMember()

Return the current lead member

Specified by:

getCurrentMember in class SelectionTest

getNumMembersOfInterest

protected int getNumMembersOfInterest()

Return the total number of lead member candidates

Specified by:

getNumMembersOfInterest in class SelectionTest

getNumClients

protected int getNumClients()

Return the number of client members in this test as we want to stop them all.
