ScalarConstraint Class

Initializes a new instance with default values.

Initializes a new instance with the specified scalar and minimum value.

Initializes a new instance as a copy of an existing instance.

Initializes a new instance with the specified constrained object, scalar, and minimum value.

Initializes a new instance with the specified scalar, minimum value, and maximum value.

Initializes a new instance with the specified constrained object, scalar, minimum value, and maximum value.

Gets or sets the Access situation in which this constraint applies.

Gets or sets the object to which this constraint applies. This constraint does not use this property directly. However, when this constraint is part of a larger AccessQuery, this property identifies the participant that is observing the scalar, so event times will be moved to this participant before evaluating the scalar.

Gets or sets a logger to which debugging information will be written.

Gets or sets a number indicating the evaluation order of this constraint relative to other constraints. All constraints involved in an AccessComputation or that share a common parent (e.g. AccessQueryAnd or AccessQueryOr) in an AccessQuery are sorted by this value before being evaluated in ascending order, so constraints with a lower evaluation order are evaluated earlier than constraints with a higher evaluation order.

Gets a value indicating whether this object is frozen. A frozen object cannot be modified and an ObjectFrozenException will be thrown if an attempt is made to do so.

Gets or sets a value indicating whether a maximum threshold is used in calculating constraint satisfaction.

Gets or sets a value indicating whether a minimum threshold is used in calculating constraint satisfaction.

Gets or sets the tolerance associated with the MaximumValue to be used when computing threshold crossings.

Gets or sets the maximum function value that is allowed for this constraint to be satisfied. By default this is PositiveInfinity.

Gets or sets the tolerance associated with the MinimumValue to be used when computing threshold crossings.

Gets or sets the minimum function value that is required for this constraint to be satisfied. By default, this is NegativeInfinity.

Gets an instance describing how this constraint is to be sampled.

Gets or sets the scalar function to compare to MinimumValue and MaximumValue.

Builds a query evaluator from this constraint.

Checks to determine if another instance has the same definition as this instance and returns if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).

Clones this object using the specified context.

Computes a hash code based on the current properties of this object. Derived classes MUST override this method and compute a hash code that combines: a unique hash code seed, the base implementation result, and the hash codes of all new fields introduced by the derived class which are used in the CheckForSameDefinition(DefinitionalObject) method.

Enumerates the dependencies of this object by calling EnumerateT(T) for each object that this object directly depends upon. Derived classes which contain additional dependencies MUST override this method, call the base implementation, and enumerate dependencies introduced by the derived class.

Determines whether the specified object is equal to the current object.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Freezes this object. Further attempts to modify it will result in an ObjectFrozenException.

Called by Freeze to also freeze any objects that are considered to be a part of this object. Derived classes which contain additional aggregated objects MUST override this method, call the base implementation, and freeze aggregated objects introduced by the derived class. The objects that need to be frozen in this method are frequently created in this object's constructor and are not settable via properties.

Gets a hash code representing the definition of this object.

Returns EvaluationOrder, indicating the suggested evaluation order of this constraint when it is used as part of an AccessQuery. Queries that hold sub-queries (such as an AccessQueryAnd) generally evaluate their sub-queries in ascending order of this value, so constraints with a lower evaluation order are evaluated earlier than constraints with a higher evaluation order.

Gets an evaluator that can be used to evaluate this query for a given time or for intervals of time.

Gets an evaluator that can be used to evaluate this query for a given time or for intervals of time.

Gets an evaluator that can be used to evaluate this query for a given time or for intervals of time.

Serves as the default hash function.

Gets the Type of the current instance.

Determines if this object has the same definition as another object.

Creates a shallow copy of the current Object.

Throws ObjectFrozenException if this object IsFrozen. This method should be called from any method or property that modifies this object.

Transforms this query to disjunctive normal form (DNF).

Returns a string that represents the current object.
