AccessQuery Class

Initializes a new instance.

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

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

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.

Creates a query that is satisfied whenever all of its sub-queries are satisfied.

Creates a query which is satisfied whenever any path exists between a given transmitter and receiver. The possible paths are defined by a LinkGraph.

Creates a query which is satisfied whenever any path exists between a given transmitter and receiver. The possible paths are deduced from a list of links.

Creates a query which is satisfied whenever any path exists between a given transmitter and receiver. The possible paths are deduced from a list of links.

Creates a query that is satisfied whenever at least N of the specified sub-queries are satisfied.

Creates a query that is satisfied whenever no more than N of the specified sub-queries are satisfied.

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.

Creates a query that is satisfied whenever exactly N of the specified sub-queries are satisfied.

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.

Constructs an access query from the constraints applied to a given object. The given object can be a link, such as LinkInstantaneous or LinkSpeedOfLight, or it can be a single object, such as Platform.

Constructs an access query from the constraints applied to a given object or link. The specified object is allowed to not have any constraints, in which case will be returned. This method is identical to FromObject(IServiceProvider) except that it will not throw when the object does not provide the IAccessConstraintsService.

Gets a hash code representing the definition of this object.

Gets the suggested evaluation order of this query. Queries that hold sub-queries (such as an AccessQueryAnd) generally evaluate their sub-queries in ascending order of this value, so queries with a lower evaluation order are evaluated earlier than queries 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.

Creates a query that is satisfied whenever a given sub-query is NOT satisfied.

Creates a query that is satisfied whenever any of its sub-queries are satisfied.

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.

Combines two queries using a logical AND operation. The resulting query will only be satisfied when both of the input queries are satisfied.

Combines two queries using a logical OR operation. The resulting query will only be satisfied when either of the input queries are satisfied.

Inverts a query using a logical NOT operation. The new query is satisfied whenever the original is not.
