class HCL_FunctionalProductDomainDefaultEval_d : public HCL_EvalFunctionalProductDomain_d

The purpose of the class HCL_FunctionalProductDomainDefaultEval is to relieve the implementor of a derived functional class from the necessity of also defining a derived evaluation class if there is no need to do so

Inheritance:

Public Methods

	HCL_FunctionalProductDomainDefaultEval_d ( const HCL_FunctionalProductDomain_d * ff, const HCL_Vector_d & in ) Usual constructor; requires a pointer to a functional and a reference to the input vector
virtual HCL_VectorSpace_d&	Domain () const Domain returns a reference to the domain of the underlying functional
virtual double	Value () const Value computes the value of the functional at x.
virtual void	PartialGradient ( int i, HCL_Vector_d & g ) const PartialGradient computes the component of the gradient corresponding to the ith component of the independent variable
virtual HCL_LinearOp_d*	HessianBlock ( int i, int j ) const HessianBlock creates the (i,j) block of the Hessian, as a linear operator with adjoint
virtual ostream&	Write ( ostream & str ) const Debugging information

virtual void HessianBlockImage( int i, int j, const HCL_Vector_d & dxj, HCL_Vector_d & dxi ) const

HessianBlockImage computes the image of the (i,j) block of the Hessian on dxj, yielding dxi. This method calls the corresponding method from the underlying functional class.

HCL_FunctionalProductDomainDefaultEval_d( const HCL_FunctionalProductDomain_d * ff, const HCL_Vector_d & in )

Usual constructor; requires a pointer to a functional and a reference to the input vector

virtual HCL_VectorSpace_d& Domain() const

Domain returns a reference to the domain of the underlying functional

virtual double Value() const

Value computes the value of the functional at x.

virtual void PartialGradient( int i, HCL_Vector_d & g ) const

PartialGradient computes the component of the gradient corresponding to the ith component of the independent variable

virtual HCL_LinearOp_d* HessianBlock( int i, int j ) const

HessianBlock creates the (i,j) block of the Hessian, as a linear operator with adjoint. This method checks to see if the functional class has implemented HessianBlock1 to compute this block; otherwise, an instance of HCL_FunctionalDefaultHessianBlock_d is created, which assumes that HessianBlockImage has been implemented in the functional class.

virtual ostream& Write( ostream & str ) const

Debugging information. Write must be implemented in derived classes, and should print a description of the object that will be useful for debugging.
