Method Details

processStreamedPart

public int processStreamedPart(TransactionCallback callback,
 PublicKey sourceKey)
                        throws HandleException

Process the incoming stream and call the given callback for every transaction that is retrieved. The status codes that this function can return include SENDING_TRANSACTIONS, or NEED_TO_REDUMP. If NEED_TO_REDUMP is returned, all of the handles should be requested from all of the servers in the primary site.

Throws:

HandleException

streamResponse

public void streamResponse(SignedOutputStream sout)
                    throws HandleException

Write the response to the specified output stream. This will send all of the transactions that hash to the requestor beginning with the specified transaction ID. This method is typically called on the server side.

Overrides:

Throws:

HandleException
