ExceptionConverter<E extends Exception, T> class abstract base

An abstract class that converts an exception E to a Failure if exception E occurs while running observe .

If no error occurs, then value T is returned.

While a single ExceptionConverter may not be very useful on its own, you can use a group of exception converters together in an ExceptionConverterSuite to run a task and automatically convert any exceptions that are thrown into the appropriate Failure object.
