int CoinWarmStartPrimalDual::dualSize ( ) const

return the size of the dual vector

Definition at line 21 of file CoinWarmStartPrimalDual.hpp.

const double* CoinWarmStartPrimalDual::dual ( ) const
inline

return a pointer to the array of duals

Definition at line 23 of file CoinWarmStartPrimalDual.hpp.

int CoinWarmStartPrimalDual::primalSize ( ) const

return the size of the primal vector

const double* CoinWarmStartPrimalDual::primal ( ) const

return a pointer to the array of primals

Definition at line 28 of file CoinWarmStartPrimalDual.hpp.

void CoinWarmStartPrimalDual::assign ( int  primalSize,
int  dualSize,
double *&  primal,
double *&  dual 
)
inline

Assign the primal/dual vectors to be the warmstart information.

In this method the object assumes ownership of the pointers and upon return primal and dual will be a NULL pointers. If copying is desirable use the constructor.

NOTE: primal and dual must have been allocated by new double[], because they will be freed by delete[] upon the desructtion of this object...

Definition at line 53 of file CoinWarmStartPrimalDual.hpp.

void CoinWarmStartPrimalDual::clear ( )
inline

Clear the data.

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

void CoinWarmStartPrimalDual::swap ( CoinWarmStartPrimalDual rhs)
inline

Definition at line 71 of file CoinWarmStartPrimalDual.hpp.

virtual CoinWarmStart* CoinWarmStartPrimalDual::clone ( ) const
inlinevirtual

`Virtual constructor'

Implements CoinWarmStart.

Definition at line 79 of file CoinWarmStartPrimalDual.hpp.

virtual CoinWarmStartDiff* CoinWarmStartPrimalDual::generateDiff ( const CoinWarmStart *const  oldCWS) const
virtual

Generate a `diff' that can convert the warm start passed as a parameter to the warm start specified by this.

The capabilities are limited: the basis passed as a parameter can be no larger than the basis pointed to by this.

Reimplemented from CoinWarmStart.

virtual void CoinWarmStartPrimalDual::applyDiff ( const CoinWarmStartDiff *const  cwsdDiff)
virtual

Apply diff to this warm start.

Update this warm start by applying diff. It's assumed that the allocated capacity of the warm start is sufficiently large.

Reimplemented from CoinWarmStart.
