LSBBExpression Class¶

class localsolver.LSBBExpression¶: Mathematical modeling expression. Expressions are used to build the mathematical optimization model associated to LocalSolverBlackBox. An expression is composed of an operator (which corresponds to its type) and its operands (which are other expressions of the model).

Summary¶

Methods¶
`GetModel`	Returns the model object associated to this expression.
`GetLocalSolverBlackBox`	Returns the LocalSolverBlackBox object associated to this expression.
`IsDouble`	Returns true if this expression is a double, false otherwise.
`IsInt`	Returns true if this expression is an integer, false otherwise.
`IsBool`	Returns true if this expression is a boolean (ie 0 or 1), false otherwise.
`AddOperand`	Add the given operand to this expression.

Instance methods¶

LSBBModel GetModel()¶

Returns the model object associated to this expression.

Returns:	LSBBModel object.
Return type:	LSBBModel

LocalSolverBlackBox GetLocalSolverBlackBox()¶

Returns the LocalSolverBlackBox object associated to this expression.

Returns:	LocalSolverBlackBox object
Return type:	LocalSolverBlackBox

bool IsDouble()¶

Returns true if this expression is a double, false otherwise. Only allowed in states LSBBState.Paused or LSBBState.Stopped.

Returns:	True if the expression is a double.
Return type:	bool

bool IsInt()¶

Returns true if this expression is an integer, false otherwise. Only allowed in states LSBBState.Paused or LSBBState.Stopped. Note that a boolean is also an integer.

Returns:	True if the expression is an integer.
Return type:	bool

bool IsBool()¶

Returns true if this expression is a boolean (ie 0 or 1), false otherwise. Only allowed in states LSBBState.Paused or LSBBState.Stopped.

Returns:	True if the expression is a boolean.
Return type:	bool

void AddOperand(LSExpression operand)¶

Add the given operand to this expression. The operand can be an LSBBExpression, a boolean, an integer or a double. Only allowed in state LSBBState.Modeling.

Arguments:	operand (LSExpression) – Operand to add. Can be an LSBBExpression, a boolean, an integer or a double.
