                                           Integer level)

Get the graph of nodes and Lines radiating out from a node.

Return the nodes and Lines that radiate out from the supplied node (identified by a GUID). The results are scoped by types of Lines, types of nodes and classifications as well as level.

Parameters:

userId - userId under which the request is performed

guid - the starting point of the query.

nodeFilterStr - Comma separated list of node names to include in the query results. Null means include all entities found, irrespective of their type.

lineFilterStr - comma separated list of line names to include in the query results. Null means include all Lines found, irrespective of their type.

asOfTime - Requests a historical query of the relationships for the entity. Null means return the present values.

statusFilter - By default only active instances are returned. Specify ALL to see all instance in any status.

level - the number of the Lines (relationships) out from the starting node that the query will traverse to gather results. If not specified then it defaults to 3.

Returns:

A graph of nodeTypes.

• UnrecognizedGUIDException the supplied guid was not recognised
• UserNotAuthorizedException the requesting user is not authorized to issue this request.
• MetadataServerUncontactableException not able to communicate with a Metadata respository service.
• InvalidParameterException one of the parameters is null or invalid.
• FunctionNotSupportedException Function not supported this indicates that a find was issued but the repository does not implement find functionality in some way.
