PartitionBlobTranslator11g (Oracle Spatial and Graph Java API Reference)

java.lang.Object
- oracle.spatial.network.lod.PartitionBlobTranslator11g

All Implemented Interfaces:

PartitionBlobTranslator
```
public class PartitionBlobTranslator11g
extends java.lang.Object
implements PartitionBlobTranslator
```
The class to translate a network partition BLOB to a LogicalPartition object, or vice versa.
Structure of a BLOB:
A partition BLOB consists of 3 sections:
header: summary info about the partition
nodes (internal and external): number of nodes and list of nodes
Each node consists of the following fields: node id, node cost, is_active, node partition id, userdata
links: number of links and list of links
Each link consists of the following fields: link id, link level, start node id, end node id, link cost, is_bidirected, is_active, userdata

Since:: Oracle Database 11g Release 1 (11.1)

    Description copied from interface: PartitionBlobTranslator
    
    Reads a partition BLOB from the specified input stream and translates it into a LogicalPartition object.
    
    Specified by:
    
    blobToPartition in interface PartitionBlobTranslator
    
    Parameters:
    
    networkName - network name
    
    partitionId - partition ID
    
    partitionLevel - link level for the partition
    
    is - input stream
    
    loadUserData - whether to include the user data into the returned LogicalPartition object
    
    Returns:
    
    logical partition
    
    Throws:
    
    LODNetworkException

                               boolean includeUserData)
                        throws LODNetworkException
```
    Description copied from interface: PartitionBlobTranslator
    
    Translates the LogicalPartition object into a partition BLOB, and outputs it into the specified output stream.
    
    Specified by:
    
    partitionToBlob in interface PartitionBlobTranslator
    
    Parameters:
    
    partition - logical partition
    
    os - output stream
    
    includeUserData - whether to include user data in the generated partition BLOB
    
    Returns:
    
    whether user data is included in the generated partition BLOB. User data is includes in the partition BLOB if the input logical partition contains users data and the input includeUserData flag is set to true.
    
    Throws:
    
    LODNetworkException
