Member Function Documentation

template<class TYPE , class ACCESSOR >

static int bdlat::NullableValueUtil::accessValueByCategory	(	const TYPE &	object,
		ACCESSOR &	accessor
	)			[static]

Invoke the specified accessor on the non-modifiable value stored in the specified "nullable" object and on a prvalue of the category tag type for the dynamic category of the value. See bdlat_typecategory|Category Tags and Enumerators for documentation about category tags. Return the value from the invocation of accessor. The accessor must be an accessor functor. See bdlat_typecategory'|'ACCESSOR Functors for the requirements on accessor. The behavior is undefined if object contains a null value.

template<class TYPE , class MANIPULATOR >

static int bdlat::NullableValueUtil::manipulateValueByCategory	(	TYPE *	object,
		MANIPULATOR &	manipulator
	)			[static]

Invoke the specified manipulator on the address of the value stored in the specified "nullable" object and on a prvalue of the category tag type for the dynamic category of the value. See bdlat_typecategory|Category Tags and Enumerators for documentation about category tags. Return the value from the invocation of manipulator. The manipulator must be a manipulator functor. See bdlat_typecategory'|'MANIPULATOR Functors for the requirements on manipulator. The behavior is undefined if object contains a null value.
