```
    Generates partition BLOBs for the specified link level. This method reads partition information from the network node and link tables/views directly, and writes the partition information to BLOB.
    
    Parameters:
    
    linkLevel - link level
    
    includeUserData - whether to include user data or not. If set to true, user data of category 0 will be included in the blob.
    
    commitForEachBlob - whether to call commit after writing the BLOB for each partition
    
    Throws:

                     throws LODNetworkException
```
    Generates partition BLOBs for all link levels. Depending on the value of the flag performDeltaUpdate, partition information can be read from the original network node and link tables/views, or from the existing partition BLOBs combined with the information from the network update history table.
    
    Parameters:
    
    includeUserData - whether to include user data or not. If set to true, user data of category 0 will be included in the blob.
    
    commitForEachBlob - whether to call commit after writing the BLOB for each partition
    
    performDeltaUpdate - whether to use network update history to perform delta update on existing BLOBs or to reload the network information directly from the network node and link tables/views.
    
    Throws:
    
    LODNetworkException
