Method Detail

getNextTransformer

public UMOStreamingTransformer getNextTransformer()

Transformers can be chained together and invoked in a series

Returns:

the next transformer to invoke after this one

setNextTransformer

public void setNextTransformer(UMOStreamingTransformer nextTransformer)

Transformers can be chained together and invoked in a series

Parameters:

nextTransformer - the next transforer to invoke

transform

public Object transform(InputStream src,
                        OutputStream dest,
                        String encoding)
                 throws TransformerException

Thransforms the supllied data and returns the result

Parameters:

src - the inputStream

encoding - the encoding to use in this transformation (if necessary)

Returns:

the transformed data

Throws:

TransformerException - if a error occurs transforming the data or if the expected returnClass isn't the same as the transformed data
