Method Detail

init

void init(java.sql.Connection conn,
          NetworkMetadata networkMetadata)

Initialize the user data IO implementation. This sets the database connection and the network metadata.

Parameters:

conn - database connection

networkMetadata - network metadata

readUserData

java.util.Map<java.lang.String,java.lang.Object>[] readUserData(java.lang.String type,
                                                                long[] ids)

Reads user defined data from the database.

Parameters:

type - user data type, which can take the following values:
- UserDataMetadata.NODE_TABLE_TYPE
- UserDataMetadata.LINK_TABLE_TYPE
- UserDataMetadata.PATH_TABLE_TYPE

ids - the IDs of the objects for which the user data are read

Returns:

array of user data maps, each corresponding to an ID of the same index in the ID array.

writeUserData

void writeUserData(java.lang.String type,
                   long[] ids,
                   java.util.Map<java.lang.String,java.lang.Object>[] userData)

Parameters:

type - user data type, which can take the following values:
- UserDataMetadata.NODE_TABLE_TYPE
- UserDataMetadata.LINK_TABLE_TYPE
- UserDataMetadata.PATH_TABLE_TYPE

ids - the IDs of the objects for which the user data are written out

userData - array of user data maps, each corresponding to an ID of the same index in the ID array.
