processorType
The processor type of the saga being tested, extracted from the generic type parameter.
This property uses reflection to determine the saga class type from the subclass's generic type argument. It accesses the ParameterizedType of the superclass to retrieve the actual type argument at index 0, which corresponds to T.
Return
The Class object for the saga type T.
Throws
if the generic superclass is not a ParameterizedType.
