Method Detail

transform

Object transform(Object src,
                 Event event)
          throws MessageTransformerException

Transforms the supplied data and returns the result

Parameters:

src - the data to transform

event - the event currently being processed

Returns:

the transformed data

Throws:

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

transform

Object transform(Object src,
                 Charset encoding,
                 Event event)
          throws MessageTransformerException

Transforms the supplied data and returns the result

Parameters:

src - the data to transform

encoding - the encoding to use by this transformer. many transformations will not need encoding unless dealing with text so you only need to use this method if yo wish to customize the encoding

event - the event currently being processed

Returns:

the transformed data

Throws:

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