Detailed Description

A `diff' between two CoinWarmStartPrimalDual objects.

This class exists in order to hide from the world the details of calculating and representing a `diff' between two CoinWarmStartPrimalDual objects. For convenience, assignment, cloning, and deletion are visible to the world, and default and copy constructors are made available to derived classes. Knowledge of the rest of this structure, and of generating and applying diffs, is restricted to the friend functions CoinWarmStartPrimalDual::generateDiff() and CoinWarmStartPrimalDual::applyDiff().

The actual data structure is a pair of vectors, #diffNdxs_ and #diffVals_.

Constructor & Destructor Documentation

virtual CoinWarmStartPrimalDualDiff::~CoinWarmStartPrimalDualDiff ( )


Definition at line 159 of file CoinWarmStartPrimalDual.hpp.

CoinWarmStartPrimalDualDiff::CoinWarmStartPrimalDualDiff ( )

Default constructor.

This is protected (rather than private) so that derived classes can see it when they make their default constructor protected or private.

Definition at line 169 of file CoinWarmStartPrimalDual.hpp.

CoinWarmStartPrimalDualDiff::CoinWarmStartPrimalDualDiff ( const CoinWarmStartPrimalDualDiff rhs)

Copy constructor.

For convenience when copying objects containing CoinWarmStartPrimalDualDiff objects. But consider whether you should be using clone() to retain polymorphism.

This is protected (rather than private) so that derived classes can see it when the make their copy constructor protected or private.

Member Function Documentation

virtual CoinWarmStartDiff* CoinWarmStartPrimalDualDiff::clone ( ) const

`Virtual constructor'.

To be used when retaining polymorphism is important

Implements CoinWarmStartDiff.

void CoinWarmStartPrimalDualDiff::clear ( )

Clear the data.

Make it appear as if the diff was just created using the default constructor.
