## Detailed Description

A `diff' between two CoinWarmStartDual objects.

This class exists in order to hide from the world the details of calculating and representing a `diff' between two CoinWarmStartDual 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 CoinWarmStartDual::generateDiff() and CoinWarmStartDual::applyDiff().

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

## Constructor & Destructor Documentation

virtual CoinWarmStartDualDiff::~CoinWarmStartDualDiff | ( |  | ) | `[inline, virtual]`

Destructor.

Definition at line 118 of file CoinWarmStartDual.hpp.

CoinWarmStartDualDiff::CoinWarmStartDualDiff | ( |  | ) | `[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 128 of file CoinWarmStartDual.hpp.

Referenced by clone().

CoinWarmStartDualDiff::CoinWarmStartDualDiff | ( | const CoinWarmStartDualDiff & | rhs | ) | `[inline, protected]`

Copy constructor.

For convenience when copying objects containing CoinWarmStartDualDiff 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 140 of file CoinWarmStartDual.hpp.

CoinWarmStartDualDiff::CoinWarmStartDualDiff | ( | int | sze,
|  | const unsigned int *const | diffNdxs,
|  | const double *const | diffVals |
| ) |  |  | `[inline, private]`

Standard constructor.
