Method Detail

collectCheckpoints

protected void collectCheckpoints(javax.management.openmbean.TabularDataSupport tab)
                           throws javax.management.openmbean.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:

javax.management.openmbean.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 java.lang.String createCheckpoint(long lifetime)

Description copied from interface: CheckpointMBean

Create a new checkpoint with the given lifetime. See org.apache.jackrabbit.oak.spi.state.NodeStore#checkpoint

Returns:

the id of the newly created checkpoint

releaseCheckpoint

public boolean releaseCheckpoint(java.lang.String checkpoint)

Description copied from interface: CheckpointMBean

Release the checkpoint with the given id. See org.apache.jackrabbit.oak.spi.state.NodeStore#checkpoint

Returns:

true on success, false otherwise.
