virtual double BeliefInterface::InnerProduct ( const std::vector< double > & values ) const

pure virtual

Computes the inner product of a belief with the vector values.

virtual std::vector<double> BeliefInterface::InnerProduct ( const VectorSet & v ) const

pure virtual

Computes the inner product of a belief with the VectorSet v.

Returns the inner product with each vector in v.

Implemented in BeliefSparse, and Belief.

virtual std::vector<double> BeliefInterface::InnerProduct	(	const VectorSet &	v,
		const std::vector< bool > &	mask
	)		const

pure virtual

Computes the inner product of a belief with the VectorSet v.

Returns the inner product with each vector in v, but only for vectors whose mask is set to true.

Implemented in BeliefSparse, and Belief.

virtual BeliefInterface& BeliefInterface::operator= ( const BeliefInterface & o )

pure virtual

Copy assignment operator.

This must be implemented by the derived class (with this prototype). For an example, see PolicyPoolJPolValPair.

For now, this function is purely abstract. Might there be some members added to this (base) class, then an implementation could be made. This should then be called using PolicyPoolInterface::operator=(o) from the copy assignment operator of the derived class. See also http://www.icu-project.org/docs/papers/cpp_report/the_assignment_operator_revisited.html.

Implemented in BeliefSparse, and Belief.
