public abstract class AIOTransducer

extends ATransducer

implements IIOTransducer

Provides an abstract base class for implementors of the IIOTransducer interface.

Performs Transduction against a stream of data from either a Reader or a Writer.

This transduction occurs both ways; put() takes data from the IMetaCollection instance to which this ITransducer instance is attached and places it into the data source represented by this ITransducer instance. The get() method takes data from the data source represented by this ITransducer instance and places it into the IMetaCollection instance to which this ITransducer instance is attached.

This IIOTransducer instance provides stream-based access for stream-based ITransducer implementors. It abstracts out the setting and getting of the streams, or the Readers and Writers, into this interface.

For specific type of streams, like file-based streams or string-based streams, see the TransducerAdapter objects.

This implementation provides storage for the Reader and Writer instances.
