loadConfig

public static void loadConfig(CLOB configXml)
                       throws LODNetworkException

Reloads the configuration xml.

Parameters:

configXml - configuration xml

Throws:

LODNetworkException

generatePartitionBlob

public static void generatePartitionBlob(java.lang.String networkName,
                                         int linkLevel,
                                         int partitionId,
                                         boolean includeUserData)
                                  throws LODNetworkException

Writes partition BLOBs into partition blob table. The caller needs to make sure that the partition blob table already exists before calling this method.

Parameters:

networkName - network name

linkLevel - link level

partitionId - partition ID

includeUserData - is user defined data included in the BLOB

Throws:

LODNetworkException

generatePartitionBlobs

public static void generatePartitionBlobs(java.lang.String networkName,
                                          int linkLevel,
                                          java.lang.String partitionBlobTable,
                                          boolean includeUserData,
                                          boolean commitForEachBlob)
                                   throws LODNetworkException

Writes partition BLOBs into partition blob table. The caller needs to make sure that the partition blob table already exists before calling this method.

Parameters:

networkName - network name

linkLevel - link level

partitionBlobTable - partition BLOB table name

includeUserData - is user defined data included in the BLOBs

Throws:

LODNetworkException

findConnectedComponents

public static void findConnectedComponents(java.lang.String networkName,
                                           int linkLevel,
                                           java.lang.String componentTable)
                                    throws LODNetworkException

Find the connected components and writes the node component relationship into component table. The caller needs to make sure that the component table already exists before calling this method.

Parameters:

networkName - network name

linkLevel - link level

componentTable - connected component table name

Throws:

LODNetworkException

getPartitionSize

public static long getPartitionSize(java.lang.String networkName,
                                    int partitionId,
