Default Compiler Generated Methods

(Hidden to avoid implicit creation/calling).

These methods are not implemented and we do not want the compiler to implement them for us, so we declare them private and do not define them. This ensures that they will not be implicitly created/called.

Constructor & Destructor Documentation

◆ InexactNewtonNormalStep() [1/3]

Ipopt::InexactNewtonNormalStep::InexactNewtonNormalStep ( SmartPtr< AugSystemSolver aug_solver)

Default onstructor.

◆ ~InexactNewtonNormalStep()

virtual Ipopt::InexactNewtonNormalStep::~InexactNewtonNormalStep ( )
virtual

Default destructor.

◆ InexactNewtonNormalStep() [2/3]

Ipopt::InexactNewtonNormalStep::InexactNewtonNormalStep ( )
private

Default onstructor.

◆ InexactNewtonNormalStep() [3/3]

Ipopt::InexactNewtonNormalStep::InexactNewtonNormalStep ( const InexactNewtonNormalStep )
private

Copy Constructor.

Member Function Documentation

◆ InitializeImpl()

virtual bool Ipopt::InexactNewtonNormalStep::InitializeImpl ( const OptionsList options,
const std::string &  prefix 
)
virtual

◆ ComputeNewtonNormalStep()

virtual bool Ipopt::InexactNewtonNormalStep::ComputeNewtonNormalStep ( Vector newton_x,
Vector newton_s 
)
virtual

Method for computing the normal step.

The computed step is returned as normal_x and normal_s, for the x and s variables, respectively. These quantities are not in the original space, but in the space scaled by the slacks. If the step cannot be computed, this method returns false.

◆ RegisterOptions()

static void Ipopt::InexactNewtonNormalStep::RegisterOptions ( SmartPtr< RegisteredOptions roptions)
static

Methods for IpoptType.

◆ InexData()

InexactData& Ipopt::InexactNewtonNormalStep::InexData ( )
inlineprotected

Method to easily access Inexact data.

Definition at line 51 of file IpInexactNewtonNormal.hpp.

◆ InexCq()

InexactCq& Ipopt::InexactNewtonNormalStep::InexCq ( )
inlineprotected

Method to easily access Inexact calculated quantities.

Definition at line 60 of file IpInexactNewtonNormal.hpp.

◆ operator=()

void Ipopt::InexactNewtonNormalStep::operator= ( const InexactNewtonNormalStep )
private

Overloaded Equals Operator.

Member Data Documentation

◆ aug_solver_

SmartPtr<AugSystemSolver> Ipopt::InexactNewtonNormalStep::aug_solver_
private

Object to be used to solve the augmented system.
