Detailed Description

The class for variables of a Mathematical Programming (MP) model.

Definition at line 16 of file MPVariable.java.

Constructor & Destructor Documentation

◆ MPVariable()

com.google.ortools.linearsolver.MPVariable.MPVariable ( long cPtr,
boolean cMemoryOwn )
protected

Definition at line 20 of file MPVariable.java.

Member Function Documentation

◆ basisStatus()

MPSolver.BasisStatus com.google.ortools.linearsolver.MPVariable.basisStatus ( )

Advanced usage: returns the basis status of the variable in the current
solution (only available for continuous problems).

See also
MPSolver::BasisStatus.

Definition at line 137 of file MPVariable.java.

◆ delete()

synchronized void com.google.ortools.linearsolver.MPVariable.delete ( )

Definition at line 46 of file MPVariable.java.

◆ finalize()

void com.google.ortools.linearsolver.MPVariable.finalize ( )
protected

Definition at line 42 of file MPVariable.java.

◆ getCPtr()

static long com.google.ortools.linearsolver.MPVariable.getCPtr ( MPVariable obj)
staticprotected

Definition at line 25 of file MPVariable.java.

◆ index()

int com.google.ortools.linearsolver.MPVariable.index ( )

Returns the index of the variable in the MPSolver::variables_.

Definition at line 84 of file MPVariable.java.

◆ lb()

double com.google.ortools.linearsolver.MPVariable.lb ( )

Returns the lower bound.

Definition at line 91 of file MPVariable.java.

◆ name()

String com.google.ortools.linearsolver.MPVariable.name ( )

Returns the name of the variable.

Definition at line 59 of file MPVariable.java.

◆ reducedCost()

double com.google.ortools.linearsolver.MPVariable.reducedCost ( )

Advanced usage: returns the reduced cost of the variable in the current
solution (only available for continuous problems).

Definition at line 127 of file MPVariable.java.

◆ setBounds()

void com.google.ortools.linearsolver.MPVariable.setBounds ( double lb,
double ub )

Sets both the lower and upper bounds.

Definition at line 119 of file MPVariable.java.

◆ setInteger()

void com.google.ortools.linearsolver.MPVariable.setInteger ( boolean integer)

Sets the integrality requirement of the variable.

Definition at line 66 of file MPVariable.java.

◆ setLb()

void com.google.ortools.linearsolver.MPVariable.setLb ( double lb)

Sets the lower bound.

Definition at line 105 of file MPVariable.java.

◆ setUb()

void com.google.ortools.linearsolver.MPVariable.setUb ( double ub)

Sets the upper bound.

Definition at line 112 of file MPVariable.java.

◆ solutionValue()

double com.google.ortools.linearsolver.MPVariable.solutionValue ( )

Returns the value of the variable in the current solution.

If the variable is integer, then the value will always be an integer (the
underlying solver handles floating-point values only, but this function
automatically rounds it to the nearest integer; see: man 3 round).

Definition at line 77 of file MPVariable.java.

◆ swigRelease()

static long com.google.ortools.linearsolver.MPVariable.swigRelease ( MPVariable obj)
staticprotected

Definition at line 29 of file MPVariable.java.

◆ ub()

double com.google.ortools.linearsolver.MPVariable.ub ( )

Returns the upper bound.

Definition at line 98 of file MPVariable.java.
