Detailed Description

A detector which detect whether a function throws an exception of a given type.

If the detected function throws an exception of the expected type then this class returns ExceptionThrown.

Note: This detector also matches exceptions derived from the expected type. If an exception type B derives from A, Throws<A> returns a failure if an instance of B is thrown.

Warning: When using several Throws in an Any detector be sure to put instance especting the most specific exception first and the least specific exception last, otherwise the latter will always detect the exception and the most specific one will never be called.

Template Parameters

T	The type of the exception.

Member Function Documentation

template<typename T >

template<typename Q >

returned_failure_t<typename FailureDetectorTag<ExceptionThrown<T> >::failure_types> resilient::Throws< T >::detect ( ICallResult< Q > & result )

inline

Check whether the result contains an exception of the expected type.

Template Parameters

Q	The return type of the detected function

Parameters

result The result of invoking the detected function.

Returns: ExceptionThrown if an exception occurred and the type is the expected one, NoFailure otherwise.
