WritingStrategy

interface WritingStrategy

WritingStrategy is used by the OutputStreamAdapter to determine how writing to the WritableDataProvider is handled. Writing works in three steps:

prepare is called before any writing takes place.
write is called until all data has been written.
finishWriting is called once all data has been written.

It is the WritingStrategys responsibility to call OutputStreamAdapter.writeToDataProvider and OutputStreamAdapter.finishWritingToDataProvider at the appropriate times.
