5.7 Operation

An enumeration type for specifying the mode of operation of a Transformer instance, when wired into an Assembly.

This class cannot be instantiated; but its (only) two possible values can be used for constructing Transformer elements:

• PRE_PROCESSING: to mean that the input data is first processed by the current Transformer before being passed to the rest of the chain; and
• POST_PROCESSING: to mean that the input data is first passed to the rest of the chain, and the resulting bytes are then processed by the current Transformer.
