Constructor & Destructor Documentation

JointNPVCube() [1/2]

JointNPVCube	(	const QuantLib::ext::shared_ptr< NPVCube > &	cube1,
		const QuantLib::ext::shared_ptr< NPVCube > &	cube2,
		const std::set< std::string > &	ids = {},
		const bool	requireUniqueIds = true,
		const std::function< Real(Real a, Real x)> &	accumulator = [](Real a, Real x) { return a+x;},
		const Real	accumulatorInit = 0.0
	)

ctor for two input cubes

JointNPVCube() [2/2]

JointNPVCube	(	const std::vector< QuantLib::ext::shared_ptr< NPVCube >> &	cubes,
		const std::set< std::string > &	ids = {},
		const bool	requireUniqueIds = true,
		const std::function< Real(Real a, Real x)> &	accumulator = [](Real a, Real x) { return a+x;},
		const Real	accumulatorInit = 0.0
	)

ctor for n input cubes

• If no ids are given, the ids in the input cubes define the ids in the resulting cube. The order is lexicographic. If ids are given they define the ids in the output cube.
• If requireUniqueIds is true, there must be no duplicate ids in the input cubes. If requireUniqueIds is false, they may be duplicate ids in which case get() will return an aggregate of the entries in the input cubes over the matching ids using the accumulator function and accumulator initialization.
• If one id in the result cube corresponds to several input cubes, it is not allowed to call set on this id, this will result in an exception.
