Method Detail

Value process(Value value)
       throws ProcessingException

Called to process a given value.

Implementers should catch any exception and wrap them in a ProcessingException.

Depending on the use case, if the given value null, the Processor should return null.

It lies in the responsibility of the caller, to handle unwanted null-values by replacing them with a sensible default value or throwing an appropriate ProcessingException.

Parameters:

value - The value to be processed.

Returns:

The processed value.

Throws:

ProcessingException - If the conversion failed.
