_logLevel

protected Level _logLevel

The current level of logging verbosity for this object.

applicationId

protected String applicationId

The application id

clusterId

protected String clusterId

The cluster id

Constructor Detail

HAStoreBase

public HAStoreBase(JavaEEIOUtils ioUtils)

Creates a new instance of HAStoreBase

Method Detail

debug

protected void debug(String message)

setLogLevel

protected void setLogLevel()

Set _debug flag and _logLevel based on the log level.

getApplicationId

public String getApplicationId()

getClusterIdFromConfig

protected String getClusterIdFromConfig()

Return the cluster id for this Store as defined in server.xml.

getClusterId

protected String getClusterId()

Return the cluster id for this Store

getByteArray

public byte[] getByteArray(Session session)
                    throws IOException

Create serialized byte[] for obj.

Parameters:

session - - serialize obj

Returns:

byte[] containing serialized data stream for obj

Throws:

IOException

getByteArray

protected byte[] getByteArray(Session session,
                              boolean compress)
                       throws IOException

Create an byte[] for the session that we can then pass to the HA Store.

Parameters:

session - The session we are serializing

Throws:

IOException

remove

public void remove(String id)
            throws IOException

Remove the Session with the specified session identifier from this Store, if present. If no such Session is present, this method takes no action.

Parameters:

id - Session identifier of the Session to be removed

Throws:

IOException - if an input/output error occurs

doRemove

public void doRemove(String id)
              throws IOException

Remove the Session with the specified session identifier from this Store, if present. If no such Session is present, this method takes no action. (This is the non-synchronized version of remove called by a store element from the pool, not the singleton store which must use removeSynchronized

Parameters:

id - Session identifier of the Session to be removed

Throws:

IOException - if an input/output error occurs

removeSynchronized

public void removeSynchronized(String id)
                        throws IOException

Remove the Session with the specified session identifier from this Store, if present. If no such Session is present, this method takes no action.

Parameters:

id - Session identifier of the Session to be removed

Throws:

IOException - if an input/output error occurs

getSize

public int getSize()
            throws IOException

return the size of the store cache will be over-ridden in subclasses

Throws:

IOException - if an input/output error occurs
