Distinct¶

Distinct operator accepts one or two operands. With one operand, the operator takes an array and returns the unordered set of distinct values in the array. With two operands, it takes as input a collection or interval and a lambda function, and returns the unordered set of distinct values among all the values returned by the function called on each element of the given collection or interval. This operator can be used to model scheduling problems with a limited number of products types to be produced by a machine.

Python¶

• Added LSOperator.DISTINCT operator.

• Added LSModel.distinct() to create distinct expressions.

• Added a new method LSArray.is_collection() to test if a value at a given position is a collection.

C++¶

• Added O_Distinct operator.

• Added LSModel::distinct() to create distinct expressions.

• Added a new method LSArray::isCollection() to test if a value at a given position is a collection, and a new method LSArray::getCollectionValue() to retrieve the collection value at a given position.

C#¶

• Added LSOperator.Distinct operator.

• Added LSModel.Distinct to create distinct expressions.

• Added a new method LSArray.IsCollection to test if a value at a given position is a collection, and a new method LSArray.GetCollectionValue to retrieve the collection value at a given position.

Java¶

• Added LSOperator.Distinct operator.

• Added LSModel.distinct to create distinct expressions.

• Added a new method LSArray.isCollection to test if a value at a given position is a collection, and a new method LSArray.getCollectionValue to retrieve the collection value at a given position.
