Method Details

getPartitionId

int getPartitionId()

Returns the partition id (starting from 0). Note, SpaceInstance.getInstanceId() starts from 1.

getInstances

SpaceInstance[] getInstances()

Returns all the space instances that form the partition.

getSpace

Space getSpace()

Returns the Space this Space Partition is part of.

getPrimary

SpaceInstance getPrimary()

Returns the primary space instance, null if currently there is no primary.

getBackup

SpaceInstance getBackup()

Returns the (first) backup space instance, null if currently there is no backup.

waitFor

boolean waitFor(SpaceMode spaceMode)

Waits (default timeout) till one of the Space partition instances has the provided space mode.

Parameters:

spaceMode - the requested space mode (PRIMARY / BACKUP)

Returns:

returns true if a space instance was found in the default timeout, false otherwise.

Since:

14.5

waitFor

boolean waitFor(SpaceMode spaceMode,
 long timeout,
 TimeUnit timeUnit)

Waits (given timeout) till one of the Space partition instances has the provided space mode.

Parameters:

spaceMode - the requested space mode (PRIMARY / BACKUP)

timeout - the time to wait based on the time unit

timeUnit - the time unit to use for the timeout parameter

Returns:

returns true if a space instance was found in the specified timeout, false otherwise.

Since:

14.5

getSpaceModeChanged

SpaceModeChangedEventManager getSpaceModeChanged()

Returns an event manager allowing to globally register for SpaceModeChangedEventListeners that happen on any Space partition currently discovered.
