Allows to perform a trigger receive operation which control if the active receive operation will
be performed in a polling event container. This feature is mainly used when having polling event
operations with transactions where the trigger receive operation is performed outside of a
transaction thus reducing the creation of transactions did not perform the actual receive
operation.
If this method returns a non null value, it means
that the receive operation should take place. If it returns a null value, no receive operation will
be attempted, thus no transaction will be created.
