This method is used for standard and selective reverse engineering of a model. The caller persists the odiModel before invoking this method and use the returned odiModel after invocation.

Parameters:

pOdiInstance - - odiInstance to be used.

pModelId - - Id of model

pDataStoreSelection - - The type of datastores to be reversed.(All, new, existing or selected )

pDataStoreList - - List of datastores to be used. The list needs to be supplied only for SELECTED datstore selection type. For other values it should be null.

Returns:

OdiModel - Refreshed odiModel object.

Throws:

java.lang.Exception

getNewDataStores

public static java.util.List getNewDataStores(OdiInstance pOdiInstance,
                                              java.io.Serializable pModelId)
                                       throws java.lang.Exception

This method is used to get the information about the datastores which are not yet reversed in the repository.

Parameters:

pOdiInstance - - odiInstance to be used

pModelId - - OdiModel Id

Returns:

List - list of new tables which are not reversed yet in the repository.

Throws:

java.lang.Exception

doFileReverse
