Specified by:

getContent in interface DataContentHandler

Parameters:

ds - The DataSource representing the data to be converted.

Returns:

The constructed Object.

Throws:

IOException - if the data can't be accessed

IOException - if the handler doesn't support the requested flavor

getTransferDataFlavors

public ActivationDataFlavor[] getTransferDataFlavors()

Description copied from interface: DataContentHandler

Returns an array of ActivationDataFlavor objects indicating the flavors the data can be provided in. The array should be ordered according to preference for providing the data (from most richly descriptive to least descriptive).

Specified by:
