Constructor & Destructor Documentation

QuadraticCone::QuadraticCone ( )

The QuadraticCone class constructor.

Definition at line 1107 of file OSInstance.cpp.

QuadraticCone::~QuadraticCone ( )

The QuadraticCone class destructor.

Definition at line 1117 of file OSInstance.cpp.

Member Function Documentation

std::string QuadraticCone::getConeName ( ) [virtual]

Returns:: the type of cone as a string

Reimplemented from Cone.

Definition at line 1124 of file OSInstance.cpp.

std::string QuadraticCone::getConeInXML ( ) [virtual]

Write a QuadraticCone object in XML format.

This is used by OSiLWriter to write a <cone> element.

Returns:: the cone and its children as an XML string.

Implements Cone.

Definition at line 7912 of file OSInstance.cpp.

bool QuadraticCone::IsEqual ( QuadraticCone * that )

A function to check for the equality of two objects.

Reimplemented from Cone.

Definition at line 8811 of file OSInstance.cpp.

bool QuadraticCone::setRandom	(	double	density,
		bool	conformant,
		int	iMin,
		int	iMax
	)

A function to make a random instance of this class.

Parameters:

	density,:	corresponds to the probability that a particular child element is created
	conformant,:	if true enforces side constraints not enforceable in the schema (e.g., agreement of "numberOfXXX" attributes and <XXX> children)
	iMin,:	lowest index value (inclusive) that a variable reference in this matrix can take
	iMax,:	greatest index value (inclusive) that a variable reference in this matrix can take

Reimplemented from Cone.

bool QuadraticCone::deepCopyFrom ( QuadraticCone * that )

A function to make a deep copy of an instance of this class.

Parameters:

that,:

the instance from which information is to be copied

Returns:: whether the copy was created successfully

Reimplemented from Cone.

Member Data Documentation

int QuadraticCone::numberOfRows

Every cone has (at least) two dimensions; no distinction is made between vector cones and matrix cones.

Reimplemented from Cone.

Definition at line 873 of file OSInstance.h.

int QuadraticCone::numberOfColumns

Reimplemented from Cone.

Definition at line 874 of file OSInstance.h.

int QuadraticCone::numberOfOtherIndexes

Multidimensional tensors can also form cones (the Kronecker product, for instance, can be thought of as a four-dimensional tensor).

We therefore allow additional dimensions.

Reimplemented from Cone.

Definition at line 881 of file OSInstance.h.

int* QuadraticCone::otherIndexes

Reimplemented from Cone.

Definition at line 882 of file OSInstance.h.

int QuadraticCone::coneType

The type of the cone (one of the values in ENUM_CONE_TYPE).

Reimplemented from Cone.

Definition at line 885 of file OSInstance.h.

int QuadraticCone::idx

cones are referenced by an (automatically created) index

Reimplemented from Cone.

Definition at line 888 of file OSInstance.h.

double QuadraticCone::normScaleFactor

quadratic cones normally are of the form x0 >= x1^2 + x2^2 + .

.. However, the appearance can be modified using a norm factor k and a distortion matrix M to the form x0 >= p (x1, x2, ...) M (x1, x2, ...)' : k= 1, M = -1.

Definition at line 896 of file OSInstance.h.

int QuadraticCone::distortionMatrixIdx

Definition at line 897 of file OSInstance.h.

int QuadraticCone::axisDirection

The index of the first component can be changed Since there are possibly many dimensions, the index is coded as i0*n1*n2*.

.. + i1*n2*n3... + ... + i_r, where i0, i1, etc are zero-based indexes for the different dimensions: i0 = 0, 1, ..., n0 -1, where n0 is the number of rows, i1 = 0, 1, ..., n1 -1, where n1 is the number of columns, and so on for higher dimensions (if any) (: 0)
