## Constructor & Destructor Documentation

BlisBranchObjectInt::BlisBranchObjectInt | ( |  | ) | `[inline]`

Default constructor.

Definition at line 53 of file BlisBranchObjectInt.h.

BlisBranchObjectInt::BlisBranchObjectInt | ( | BlisModel * | model,
|  | int | varInd,
|  | int | direction,
|  | double | value |
| ) |  |  | `[inline]`

Construct a branching object, which branching on variable varInd.

Parameters:

  | varInd | the index of integer variable in object set
  | direction | the direction of first branching: 1(up), -1(down)
  | value | the fractional solution value of variable varInd

Definition at line 69 of file BlisBranchObjectInt.h.

BlisBranchObjectInt::BlisBranchObjectInt | ( | BlisModel * | model,
|  | int | varInd,
|  | int | intScore,
|  | double | dblScore,
|  | int | direction,
|  | double | value |
| ) |  |  | `[inline]`

Construct a branching object, which branching on variable varInd.

Parameters:

  | varInd | the index of integer variable in object set
  | intScore | the integer score/goodness
  | dblScore | the double score/goodness
  | direction | the direction of first branching: 1(up), -1(down)
  | value | the fractional solution value of variable varInd

Definition at line 91 of file BlisBranchObjectInt.h.

BlisBranchObjectInt::BlisBranchObjectInt | ( | BlisModel * | model,
|  | int | varInd,
|  | int | direction,
|  | double | lowerValue,
|  | double | upperValue |
| ) |  |  | `[inline]`

Create a degenerate branching object.

Specifies a `one-direction branch'. Calling branch() for this object will always result in lowerValue <= x <= upperValue. Used to fix a variable when lowerValue = upperValue.

Definition at line 113 of file BlisBranchObjectInt.h.

BlisBranchObjectInt::BlisBranchObjectInt | ( | const BlisBranchObjectInt & |  | ) |

Copy constructor.

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

Destructor.
