<P>
The Transformer interface Instances of this class are used to transform one type of Source to another. The instance is responsible for indicating what types of sources it can convert between. Note that a transformer is required to support the full cross-product of transformations implied by the supported input and output sources. In other words, a transformer must support transforming any supported input source to any supported output source.
