org.openspaces.admin.gsm
Interface GridServiceManagers

All Superinterfaces:
AdminAware, Iterable<GridServiceManager>

public interface GridServiceManagers
extends AdminAware, Iterable<GridServiceManager>

Grid Service Containers hold all the different GridServiceManagers that are currently discovered.

Provides simple means to get all the current managers, as well as as registering for manager lifecycle (added and removed) events.

Also provides the ability to deploy a processing unit or a space (which is also a processing unit, that simply just starts a space) on a randomly selected GSM (more control on which manager to deploy can use GridServiceManager.deploy(org.openspaces.admin.pu.ProcessingUnitDeployment).

Method Detail

getManagers

GridServiceManager[] getManagers()
Returns all the currently discovered managers.


getManagerByUID

GridServiceManager getManagerByUID(String uid)
Returns a manager based on its uid.

See Also:
GridComponent.getUid()

getUids

Map<String,GridServiceManager> getUids()
Returns a map of grid service manager with the key as the uid.


getSize

int getSize()
Returns the number of managers current discovered.


isEmpty

boolean isEmpty()
Returns true if there are no managers, false otherwise.


waitForAtLeaseOne

GridServiceManager waitForAtLeaseOne()
Waits indefinitely till at least one GSM is discovered and returns it.


waitForAtLeaseOne

GridServiceManager waitForAtLeaseOne(long timeout,
                                     TimeUnit timeUnit)
Waits for the given timeout (in time unit) till at least one GSM is discovered and returns it.


waitFor

boolean waitFor(int numberOfGridServiceManagers)
Waits indefinitely till the provided number of managers are up. When passing 0, will wait till there are no more managers.

Parameters:
numberOfGridServiceManagers - The number of managers to wait for

waitFor

boolean waitFor(int numberOfGridServiceManagers,
                long timeout,
                TimeUnit timeUnit)
Waits for the given timeout (in time unit) till the provided number of managers are up. Returns true if the required number of managers were discovered, false if the timeout expired.

When passing 0, will wait till there are no more managers.

Parameters:
numberOfGridServiceManagers - The number of managers to wait for

deploy

ProcessingUnit deploy(ProcessingUnitDeployment deployment)
Deploys a processing unit based on the processing unit deployment information on a random grid service manager (it will act as the primary GSM for the deployed processing unit).

The deployment process will wait indefinitely and return the actual processing unit that can be used.


deploy

ProcessingUnit deploy(ProcessingUnitDeployment deployment,
                      long timeout,
                      TimeUnit timeUnit)
Deploys a processing unit based on the processing unit deployment information on a random grid service manager (it will act as the primary GSM for the deployed processing unit).

The deployment process will wait for the given timeout and return the actual processing unit that can be used.


deploy

ProcessingUnit deploy(SpaceDeployment deployment)
Deploys a space based on the space deployment information on a random grid service manager (it will act as the primary GSM for the deployed processing unit).

The deployment process will wait indefinitely and return the actual processing unit that can be used.

Note, deploying just a space is simply deploying a built in processing unit that starts just an embedded space.


deploy

ProcessingUnit deploy(SpaceDeployment deployment,
                      long timeout,
                      TimeUnit timeUnit)
Deploys a space based on the space deployment information on a random grid service manager (it will act as the primary GSM for the deployed processing unit).

The deployment process will wait for the provided timeout and return the actual processing unit that can be used.

Note, deploying just a space is simply deploying a built in processing unit that starts just an embedded space.


getGridServiceManagerAdded

GridServiceManagerAddedEventManager getGridServiceManagerAdded()
Returns the grid service manager added event manager allowing to add and remove GridServiceManagerAddedEventListeners.


getGridServiceManagerRemoved

GridServiceManagerRemovedEventManager getGridServiceManagerRemoved()
Returns the grid service container added event manager allowing to add and remove GridServiceManagerRemovedEventListeners.


addLifecycleListener

void addLifecycleListener(GridServiceManagerLifecycleEventListener eventListener)
Allows to add a GridServiceManagerLifecycleEventListener.


removeLifecycleListener

void removeLifecycleListener(GridServiceManagerLifecycleEventListener eventListener)
Allows to remove a GridServiceManagerLifecycleEventListener.
