void print()
Print vector information.
void setVector(int size, const int *indices, const double *elements, bool testForDuplicateIndex=true)
just like the explicit constructor
virtual const int * getIndices() const
Get indices of elements.
CoinShallowPackedVector(bool testForDuplicateIndex=true)
Default constructor.
virtual const double * getElements() const
Get element values.
Abstract base class for various sparse vectors.
bool testForDuplicateIndex() const
Returns true if the vector should be tested for duplicate indices when they can occur.
friend void CoinShallowPackedVectorUnitTest()
A function that tests the methods in the CoinShallowPackedVector class.
const int * indices_
Vector indices.
CoinShallowPackedVector & operator=(const CoinShallowPackedVector &x)
Assignment operator.
const double * elements_
Vector elements.
virtual int getNumElements() const
Get length of indices and elements vectors.
virtual ~CoinShallowPackedVector()
Destructor.
void clear()
Reset the vector (as if were just created an empty vector)
int nElements_
Size of indices and elements vectors.
void CoinShallowPackedVectorUnitTest()
A function that tests the methods in the CoinShallowPackedVector class.
