The Decision type exposes the following members.

Constructors

	Name	Description
	Decision(Domain, String)	Initializes a new instance of the Decision class.
	Decision(Domain, String, array<Set[])	Initializes a new instance of the Decision class.

Properties

	Name	Description
	Binding	Gets or sets the LINQ binding to a database.
	Description	Gets or sets a comment for the decision object.
	IndexSets	Gets the index sets for the decision object.
	Item	Gets the indexes by one or more values.
	Name	Gets the name of the decision.

Methods

	Name	Description
	CreateBinding	Creates a DecisionBinding wrapping for the decision.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetDouble	Converts an indexed value to a double.
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetString	Retrieves a sequence of elements for the decision.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValues	Retrieves a sequence of (value, indexes) elements for this decision.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	SetBinding<T>(IEnumerable<T>, String)	Initializes a new instance of the Decision class.
	SetBinding<T>(IEnumerable<T>, String, array<String[])	Initializes a new instance of the Decision class.
	SetIndexSet	Resets the specified index set.
	SetInitialValue	Provides a value that is close to the optimal value of the decision.
	ToDouble	Converts a value to a double.
	ToString()	Converts the decision to its equivalent string representation. (Overrides Object.ToString().)
	ToString(IFormatProvider)	Converts the decision to its equivalent string representation.
	ToString(String, IFormatProvider)	Converts the decision to its equivalent string representation. (Overrides Term.ToString(String, IFormatProvider).)

Extension Methods

	Name	Description
	GetValuesByFirstIndex	Returns the values for a decision that has two index sets. (Defined by BindingUtilities.)
	GetValuesByIndex	Returns the values for a decision with a single index sets. (Defined by BindingUtilities.)

Remarks

Decisions are output variables determined by a solver. All decisions have a domain that determine the range of acceptable values. The decision may be a single value (scalar), or multiple values (a table). To create a single-value decision, pass in a zero-length indexSets array. If indexSets has nonzero length, each element of it represents a set of values which this decision is indexed by. For example, if there are two index sets, then this decision takes two indexes, one from the first set and one from the second set. The total number of decisions is the product of the sizes of all the index sets.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
