All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`MPSolver.BasisStatus`	`basisStatus()` Advanced usage: returns the basis status of the variable in the current solution (only available for continuous problems).
`void`	`delete()`
`protected void`	`finalize()`
`protected static long`	`getCPtr(MPVariable obj)`
`int`	`index()` Returns the index of the variable in the MPSolver::variables_.
`double`	`lb()` Returns the lower bound.
`java.lang.String`	`name()` Returns the name of the variable.
`double`	`reducedCost()` Advanced usage: returns the reduced cost of the variable in the current solution (only available for continuous problems).
`void`	`setBounds(double lb, double ub)` Sets both the lower and upper bounds.
`void`	`setInteger(boolean integer)` Sets the integrality requirement of the variable.
`void`	`setLb(double lb)` Sets the lower bound.
`void`	`setUb(double ub)` Sets the upper bound.
`double`	`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).
`protected static long`	`swigRelease(MPVariable obj)`
`double`	`ub()` Returns the upper bound.
