We're excited to share that we are moving forward. We're leaving behind the LocalSolver brand and transitioning to our new identity: Hexaly. This represents a leap forward in our mission to enable every organization to make better decisions faster when faced with operational and strategic challenges.

This page is for an old version of Hexaly Optimizer. We recommend that you update your version and read the documentation for the latest stable release.

LSArray Class

class LSArray

Value type for array expressions. Such value is obtained with LSExpression::getArrayValue() or LSSolution::getArrayValue(). An array contains values of type lsint, lsdouble, LSArray (for multi-dimensional arrays) or LSCollection (list or set). Note that it’s possible to mix integers or doubles in the same array. Arrays are not decisions and cannot be modified.

Summary

Functions
count Returns the number of elements in the array.
isBool Returns true if the value at the given position is a boolean.
isInt Returns true if the value at the given position is an integer.
isDouble Returns true if the value at the given position is a double.
isArray Returns true if the value at the given position is an array.
getIntValue Returns the integer value at the given position.
getDoubleValue Returns the double value at the given position.
getArrayValue Returns the array value at the given position.
toString Returns a string representation of the values in the array in the formats { val0, val1, ..., valN }.

Functions

int LSArray::count() const

Returns the number of elements in the array. Elements in arrays are indexed from 0 to count()-1.

Returns:Number of values in the array.
bool LSArray::isBool(int pos) const

Returns true if the value at the given position is a boolean. You can retrieve the value with getIntValue().

Parameters:pos – Position of the value to query.
Returns:True if the value at the given position is a boolean.
bool LSArray::isInt(int pos) const

Returns true if the value at the given position is an integer. You can retrieve the value with getIntValue().

Parameters:pos – Position of the value to query.
Returns:True if the value at the given position is an integer.
bool LSArray::isDouble(int pos) const

Returns true if the value at the given position is a double. You can retrieve the value with getDoubleValue().

Parameters:pos – Position of the value to query.
Returns:True if the value at the given position is a double.
bool LSArray::isArray(int pos) const

Returns true if the value at the given position is an array. You can retrieve the value with getArrayValue().

Parameters:pos – Position of the value to query.
Returns:True if the value at the given position is an array.
lsint LSArray::getIntValue(int pos) const

Returns the integer value at the given position. If the value is neither an integer nor a boolean, an exception is thrown.

Parameters:pos – Position of the value to query.
Returns:Integer value.
lsdouble LSArray::getDoubleValue(int pos) const

Returns the double value at the given position. If the value is not a double, an exception is thrown.

Parameters:pos – Position of the value to query.
Returns:Double value.
LSArray LSArray::getArrayValue(int pos) const

Returns the array value at the given position. If the value is not an array, an exception is thrown.

Parameters:pos – Position of the value to query.
Returns:Array value.
std::string LSArray::toString() const

Returns a string representation of the values in the array in the formats { val0, val1, ..., valN }.

Returns:String representation.
