[protected]

Use this method to set the available band-width manually.

This is the alternative to calling estimateBandWidth.

Parameters:

estimatedBandWidth

-- Guess what.

                                                                     {

(

long

estimatedTransferSize

)

[protected]

Use this method to set the download size manually.

This is the alternativ to calling estimateTransferSize.

Parameters:

estimatedTransferSize

-- what the name implies.

                                                                          {

    }

boolean de.zib.gndms.taskflows.filetransfer.server.logic.AbstractTransferQuoteCalculator< M extends FileTransferOrder >.validate

(

)

Weak order validation.

Just checks if source and destination URI are provided and are valid URI's. but NOT if the resources exist.

Returns:

true if the parameters are set.

                              {
        FileTransferOrder order = getOrderBean();
        if( order == null )
            throw new IllegalStateException( "No order provided" );

        return uriCheck( order.getSourceURI() ) && uriCheck( order.getDestinationURI() );
    }
