Function Documentation

operator!=()

template<class D >

bool operator!=	(	dds::core::null_type	,
		const dds::core::Reference< D > &	r
	)

Special operator!= used to check if this reference object does not equal the dds::core::null reference.

The non-null-check can be done like this:

if (dds::core::null != r) {
   // Use the dds reference object r
}

Returns

true if this reference is not null.

operator==()

template<class D >

bool operator==	(	dds::core::null_type	,
		const dds::core::Reference< D > &	r
	)

Special operator== used to check if this reference object does not equal the dds::core::null reference.

The non-null-check can be done like this:

if (dds::core::null == r) {
   // Do not use the dds reference object r in its current state
}

Returns

true if this reference is not null.
