Class TransferManager

java.lang.Object
oracle.ide.db.transfer.TransferManager

public final class TransferManager

extends java.lang.Object

Manage the transfer of database objects.

The source can be:

• An Offline Database
• A Database

The targets (there may be several) can be

• A Database
• An Offline Database
• A SQL script

Create a TransferDescriptor to describe the transfer. Then invoke #prepareAndTransfer(transferDescriptor)

The transfer descriptor describes:

• The source provider
• The target provider
• The database objects to transfer
• The transfer policy - this describes how to copy the transfered objects. This makes sure that any existing objects in the target are dealt with correctly.
• Transfer targets - classes which create the objects in the target.

Method Detail

getInstance

public static TransferManager getInstance()

Gets the TransferManager that can be used to create, prepare and transfer descriptors.

createDescriptor

public TransferDescriptor createDescriptor(DBObjectProvider source,
                                           DBObjectProvider target)

createDescriptor

public TransferDescriptor createDescriptor(java.lang.String sourceProviderType,
                                           java.lang.String transferTargetID)

Creates a TransferDescriptor that will transfer objects from the given source provider type to the given transfer target (identified by its transfer target id).

Parameters:

sourceProviderType - the source provider type (e.g. "db" or "offlinedb".

transferTargetID - the id of the target for transfer.

prepare

public void prepare(TransferDescriptor td)
             throws TransferFailedException

Prepare to transfer objects. The transfer is described by the the transfer descriptor. 1. get source objects 2. instantiate and invoke the transfer policy We now have: .. source objects - no longer interesting .. transfer objects - all ready to transfer .. existing objects - handy for reconcile

Parameters:

td -

Throws:

TransferFailedException

transfer

public SystemObject[] transfer(TransferDescriptor td)
                        throws TransferFailedException

Do the transfers described by the TransferDescriptor. This method expects the preparatory work to have been done

Returns:

the transfered objects

Throws:

TransferCancelledException - if the transfer is cancelled

TransferFailedException - if the transfer fails

See Also:

prepare(oracle.ide.db.transfer.TransferDescriptor)

updateChildren

public static boolean updateChildren(ResultSet rs)

prepareAndTransfer

public SystemObject[] prepareAndTransfer(TransferDescriptor td)
                                  throws TransferFailedException

Transfer the objects as described by the TransferDescriptor. A transfer is divded into two stages, prepare and transfer, this method performs both stages (i.e. the whole operation) at once.

Parameters:

td - the descriptor for the transfer

Returns:

the objects in the target that have been succesfully transfered

Throws:

TransferFailedException - if the transfer failed
