Detailed Description
This class describes a warmstart information that consists solely of the dual vector.
Definition at line 20 of file BCP_warmstart_dual.hpp.
Constructor & Destructor Documentation
| BCP_warmstart_dual::BCP_warmstart_dual | ( | ) | [inline, private] |
The default constructor creates an empty WrtParent warmstart info (i.e., no change wrt the parent).
This is a private method since only the empty_wrt_this() method should be able to use this form of creation.
Definition at line 28 of file BCP_warmstart_dual.hpp.
| BCP_warmstart_dual::BCP_warmstart_dual | ( | BCP_buffer & | buf | ) | [inline] |
Create the object by unpacking it from a buffer.
Definition at line 39 of file BCP_warmstart_dual.hpp.
| BCP_warmstart_dual::BCP_warmstart_dual | ( | const double * | first, | |
| const double * | last | |||
| ) | [inline] |
Create an explicitly stored warmstart info by considering the double array [first,last) as the dual vector.
Definition at line 42 of file BCP_warmstart_dual.hpp.
| BCP_warmstart_dual::BCP_warmstart_dual | ( | const BCP_warmstart_dual & | ws | ) | [inline] |
Copy constructor.
Definition at line 45 of file BCP_warmstart_dual.hpp.
| virtual BCP_warmstart_dual::~BCP_warmstart_dual | ( | ) | [inline, virtual] |
Create the object by unpacking it from a buffer.

Member Function Documentation
| BCP_warmstart_dual& BCP_warmstart_dual::operator= | ( | const BCP_warmstart_dual & | ) | [private] |
The assignment operator is declared but not defined to disable it.
| virtual CoinWarmStart* BCP_warmstart_dual::convert_to_CoinWarmStart | ( | ) | const [virtual] |
Return an CoinWarmStart object that can be fed to the LP engine.
The implementation for this class will return an CoinWarmStartDual object.
Implements BCP_warmstart.
| virtual BCP_storage_t BCP_warmstart_dual::storage | ( | ) | const [inline, virtual] |
Return how the warmstarting info is stored.
Implements BCP_warmstart.
Definition at line 56 of file BCP_warmstart_dual.hpp.
| virtual BCP_warmstart* BCP_warmstart_dual::clone | ( | ) | const [inline, virtual] |
Make a replica of the current warmstart information.
Implements BCP_warmstart.
Definition at line 58 of file BCP_warmstart_dual.hpp.
| virtual BCP_warmstart* BCP_warmstart_dual::empty_wrt_this | ( | ) | const [inline, virtual] |
Create a warmstart info describing that no change should be done.
This is really the task of a constructor, but BCP does not know the type of warmstart the user will use, so it will invoke this method for a warmstart that was created by the user. Tricky, isn't it?
Implements BCP_warmstart.
Definition at line 62 of file BCP_warmstart_dual.hpp.
| virtual int BCP_warmstart_dual::storage_size | ( | ) | const [inline, virtual] |
Return how much memory it'll take to pack this warmstart info.
It is used when comparing which sort of storage is smaller.
Implements BCP_warmstart.
Definition at line 68 of file BCP_warmstart_dual.hpp.
| virtual void BCP_warmstart_dual::update | ( | const BCP_warmstart *const | change | ) | [virtual] |

| const double | petol, | |||
| const double | detol | |||
| ) | const [virtual] |
| void BCP_warmstart_dual::pack | ( | BCP_buffer & | buf | ) | const [inline] |
Pack the warmstart info into a buffer.
