collectCheckpoints

protected void collectCheckpoints(TabularDataSupport tab)
                           throws OpenDataException

Description copied from class: AbstractCheckpointMBean

Called to collect the tabular data for the checkpoints. Each checkpoint should be represented by a single row in tab. Implementors should use the AbstractCheckpointMBean.toCompositeData(java.lang.String, java.lang.String, java.lang.String, java.util.Map<java.lang.String, java.lang.String>) utility method for converting the individual fields associated with a checkpoint into the correct composite data format.

Specified by:

collectCheckpoints in class AbstractCheckpointMBean

Throws:

OpenDataException

getOldestCheckpointCreationTimestamp

public long getOldestCheckpointCreationTimestamp()

Specified by:

getOldestCheckpointCreationTimestamp in interface CheckpointMBean

Specified by:

getOldestCheckpointCreationTimestamp in class AbstractCheckpointMBean

Returns:

creation timestamp of oldest checkpoint.

createCheckpoint

public String createCheckpoint(long lifetime)

Description copied from interface: CheckpointMBean
