## 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 | ( |  | ) |
| inline virtual

Destructor.

Definition at line 171 of file CoinWarmStartPrimalDual.hpp.

CoinWarmStartPrimalDualDiff::CoinWarmStartPrimalDualDiff | ( |  | ) |
| inline protected

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 180 of file CoinWarmStartPrimalDual.hpp.

CoinWarmStartPrimalDualDiff::CoinWarmStartPrimalDualDiff | ( | const CoinWarmStartPrimalDualDiff & | rhs | ) |
| inline protected

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.

Definition at line 196 of file CoinWarmStartPrimalDual.hpp.

## Member Function Documentation

virtual CoinWarmStartDiff* CoinWarmStartPrimalDualDiff::clone | ( |  | ) | const
| inline virtual

`Virtual constructor'.

To be used when retaining polymorphism is important

Implements CoinWarmStartDiff.

Definition at line 165 of file CoinWarmStartPrimalDual.hpp.

void CoinWarmStartPrimalDualDiff::clear | ( |  | ) |
| inline protected

Clear the data.

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

void CoinWarmStartPrimalDualDiff::swap | ( | CoinWarmStartPrimalDualDiff & | rhs | ) |
| inline protected

Definition at line 213 of file CoinWarmStartPrimalDual.hpp.
