Properties
  NameDescription
Public propertyDebuggingLogger
Gets or sets a logger to which debugging information will be written.
Public propertyIsFrozen
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.
(Inherited from DefinitionalObject.)

Methods
  NameDescription
Public methodStatic memberAnd
Creates a query that is satisfied whenever all of its sub-queries are satisfied.
Public methodStatic memberAnyPath(IServiceProvider, IServiceProvider, LinkGraph)
Creates a query which is satisfied whenever any path exists between a given transmitter and receiver. The possible paths are defined by a LinkGraph.
Public methodStatic memberAnyPath(IServiceProvider, IServiceProvider, IServiceProvider)
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.
Public methodStatic memberAnyPath(IServiceProvider, IServiceProvider, Int32, LinkGraph)
Creates a query which is satisfied whenever any path exists between a given transmitter and receiver. The possible paths are defined by a LinkGraph.
Public methodStatic memberAnyPath(IServiceProvider, IServiceProvider, Int32, IServiceProvider)
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.
Public methodStatic memberAnyPathT(IServiceProvider, IServiceProvider, IEnumerableT)
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.
Public methodStatic memberAnyPathT(IServiceProvider, IServiceProvider, Int32, IEnumerableT)
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.
Public methodStatic memberAtLeastN
Creates a query that is satisfied whenever at least N of the specified sub-queries are satisfied.
Public methodStatic memberAtMostN
Creates a query that is satisfied whenever no more than N of the specified sub-queries are satisfied.
Protected methodCheckForSameDefinition(AccessQuery)
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).
Protected methodCheckForSameDefinition(DefinitionalObject)
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).
(Overrides DefinitionalObjectCheckForSameDefinition(DefinitionalObject).)
Public methodClone
Clones this object using the specified context.
(Inherited from DefinitionalObject.)
Protected methodComputeCurrentDefinitionHashCode
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.
(Overrides DefinitionalObjectComputeCurrentDefinitionHashCode.)
Public methodEnumerateDependencies
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.
(Inherited from DefinitionalObject.)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Public methodStatic memberExactlyN
Creates a query that is satisfied whenever exactly N of the specified sub-queries are satisfied.
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodFreeze
Freezes this object. Further attempts to modify it will result in an ObjectFrozenException.
(Inherited from DefinitionalObject.)
Protected methodFreezeAggregatedObjects
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.
(Inherited from DefinitionalObject.)
Public methodStatic memberFromObject
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.
Public methodStatic memberFromObjectAllowNoConstraints
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.
Public methodGetDefinitionHashCode
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.)
Public methodGetEvaluationOrder
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.
Public methodGetEvaluator
Gets an evaluator that can be used to evaluate this query for a given time or for intervals of time.
Public methodGetEvaluator(IServiceProvider)
Gets an evaluator that can be used to evaluate this query for a given time or for intervals of time.
Public methodGetEvaluator(IServiceProvider, EvaluatorGroup)
Gets an evaluator that can be used to evaluate this query for a given time or for intervals of time.
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodIsSameDefinition
Determines if this object has the same definition as another object.
(Inherited from DefinitionalObject.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodStatic memberNot
Creates a query that is satisfied whenever a given sub-query is NOT satisfied.
Public methodStatic memberOr
Creates a query that is satisfied whenever any of its sub-queries are satisfied.
Protected methodThrowIfFrozen
Throws ObjectFrozenException if this object IsFrozen. This method should be called from any method or property that modifies this object.
(Inherited from DefinitionalObject.)
Public methodToDisjunctiveNormalForm
Transforms this query to disjunctive normal form (DNF).
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)

Operators
  NameDescription
Public operatorStatic memberBitwiseAnd
Combines two queries using a logical AND operation. The resulting query will only be satisfied when both of the input queries are satisfied.
Public operatorStatic memberBitwiseOr
Combines two queries using a logical OR operation. The resulting query will only be satisfied when either of the input queries are satisfied.
Public operatorStatic memberLogicalNot
Inverts a query using a logical NOT operation. The new query is satisfied whenever the original is not.
