Detailed Description
Lotsize branching object.
This object can specify a two-way branch on an integer variable. For each arm of the branch, the upper and lower bounds on the variable can be independently specified.
Variable_ holds the index of the integer variable in the integerVariable_ array of the model.

Default constructor.

| ) |
Create a lotsize floor/ceiling branch object.
Specifies a simple two-way branch. Let value = x*. One arm of the branch will be is lb <= x <= valid range below(x*), the other valid range above(x*) <= x <= ub. Specify way = -1 to set the object state to perform the down arm first, way = 1 for the up arm.

| ) |
Create a degenerate branch object.
Specifies a `one-way branch'. Calling branch() for this object will always result in lowerValue <= x <= upperValue. Used to fix in valid range

Assignment operator.
Reimplemented from CbcBranchingObject.
| virtual CbcBranchingObject* CbcLotsizeBranchingObject::clone | ( | ) | const [virtual] |
Clone.
Implements CbcBranchingObject.
| virtual double CbcLotsizeBranchingObject::branch | ( | ) | [virtual] |
Sets the bounds for the variable according to the current arm of the branch and advances the object state to the next arm.
Implements CbcBranchingObject.
| virtual void CbcLotsizeBranchingObject::print | ( | ) | [virtual] |
Print something about branch - only if log level high.
| virtual int CbcLotsizeBranchingObject::type | ( | ) | const [inline, virtual] |
Return the type (an integer identifier) of this.
Implements CbcBranchingObject.

| virtual CbcRangeCompare CbcLotsizeBranchingObject::compareBranchingObject | ( | const CbcBranchingObject * | brObj, | |
| const bool | replaceIfOverlap = false | |||
| ) | [virtual] |
Compare the this with brObj.
this and brObj must be os the same type and must have the same original object, but they may have different feasible regions. Return the appropriate CbcRangeCompare value (first argument being the sub/superset if that's the case). In case of overlap (and if replaceIfOverlap is true) replace the current branching object with one whose feasible region is the overlap.
