beforeCommit

public void beforeCommit()

NO-OP

Specified by:

beforeCommit in interface TransactionalDao

isDirty

public boolean isDirty()

Does this Session contain any changes which must be synchronized with the store?

Specified by:

isDirty in interface TransactionalDao

Returns:

true => changes are pending

flush

public void flush()

Just flushes the session

Specified by:

flush in interface TransactionalDao

deleteDeltas

public int deleteDeltas(NodeRef nodeRef)

Specified by:

deleteDeltas in interface UsageDeltaDAO

deleteDeltas

public int deleteDeltas(java.lang.Long nodeId)

Specified by:

deleteDeltas in interface UsageDeltaDAO

getTotalDeltaSize

public long getTotalDeltaSize(NodeRef nodeRef)

Description copied from interface: UsageDeltaDAO

Get the total delta size for a node.

Specified by:

getTotalDeltaSize in interface UsageDeltaDAO

Returns:

sum of delta sizes (in bytes) - can be +ve or -ve

getAndRemoveTotalDeltaSize

public long getAndRemoveTotalDeltaSize(NodeRef nodeRef)

Guard against deleting deltas committed by another transaction after calculating the delta sum above. If the expected number of deletes is different from the actual number of deletes then deltas from another committed transaction are probably being removed.

Specified by:

getAndRemoveTotalDeltaSize in interface UsageDeltaDAO

Returns:

sum of delta sizes (in bytes) - can be +ve or -ve

insertDelta

public void insertDelta(NodeRef usageNodeRef,
                        long deltaSize)

Description copied from interface: UsageDeltaDAO

Create a usage delta entry.

Specified by:

insertDelta in interface UsageDeltaDAO

deltaSize - the size change

getUsageDeltaNodes

public java.util.Set getUsageDeltaNodes()

Specified by:

getUsageDeltaNodes in interface UsageDeltaDAO
