Member Function Documentation

void BeliefSparse::Clear ( )

virtual

Clears the belief.

Implements BeliefInterface.

virtual BeliefSparse* BeliefSparse::Clone ( ) const

inlinevirtual

Returns a pointer to a copy of this class.

Implements BeliefInterface.

Reimplemented in JointBeliefSparse.

References BeliefSparse().

double BeliefSparse::Get ( Index sI ) const

inlinevirtual

Gets the probability of the sI'th state.

Implements BeliefInterface.

Referenced by AgentQMDP::Act().

std::vector<double> BeliefSparse::Get ( ) const

inlinevirtual

Gets a vector of probabilities representing the belief.

Implements BeliefInterface.

BeliefIteratorGeneric BeliefSparse::GetIterator ( ) const

virtual

Implements BeliefInterface.

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

virtual

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

Implements BeliefInterface.

vector< double > BeliefSparse::InnerProduct ( const VectorSet & v ) const

virtual

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

Returns the inner product with each vector in v.

Implements BeliefInterface.

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

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.

Implements BeliefInterface.

unsigned int BeliefSparse::NumberNonZeros ( ) const

inline

Referenced by BeliefIteratorSparse::BeliefIteratorSparse().

BeliefSparse & BeliefSparse::operator= ( const BeliefSparse & o )

References _m_b.

Referenced by JointBeliefSparse::operator=().

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

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.

Implements BeliefInterface.

double& BeliefSparse::operator[] ( Index & i )

inlinevirtual

Gets the probability of the i'th state.

Implements BeliefInterface.

double& BeliefSparse::operator[] ( int & i )

inlinevirtual

Gets the probability of the i'th state.

Implements BeliefInterface.

void BeliefSparse::Print ( ) const

inlinevirtual

Prints the belief.
