Macro Definition Documentation

#define DISTI_STATIC_ASSERT	(		expr,
			msg
	)		static_assert( expr, DISTI_PREPROC_STRINGIFY( msg ) )

Uses C++11's static_assert() because it is available on this platform.

Parameters

expr	a compile-time integral or pointer expression
msg	a C identifier that will appear in compiler diagnostics

Note

For older compilers' benefit, msg should be a C identifier such as:

DISTI_STATIC_ASSERT( (std::is_convertible<T*,ConvertsTo*>::value), class_does_not_inherit_from_##ConvertsTo )

which shows a compile-time error that typically includes: "ERROR_class_does_not_inherit_from_Group". If it is not a C identifier, you may get spurious error messages at compile time compilers without static_assert.

#define DISTI_STATIC_ASSERT_IS_CONVERTIBLE_TO	(		T,
			ConvertsTo
	)		DISTI_STATIC_ASSERT( ( std::is_convertible<T*, ConvertsTo*>::value ), class_does_not_inherit_from_##ConvertsTo );

Convenience macro to check that one type converts to another at compile-time.

Parameters

T	A class to check
ConvertsTo	A class to test T* against to verify that it can be converted to ConvertsTo* without a cast.

#define DISTI_STATIC_ASSERT_STR	(		expr,
			msg
	)		static_assert( expr, msg )

Uses C++11's static_assert() because it is available on this platform.

Parameters

expr	a compile-time integral or pointer expression with a string message.
msg	a string to help the developer determine what went wrong. DISTI_STATIC_ASSERT_STR( (std::is_convertible<T*, Base*>::value), "Class does not inherit from Base." );
