AccessEntityFilterTEntity Class

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

Initializes a new instance. The Query property must be set and then ApplyChanges(EvaluatorGroup) must be called before this filter can be used.

Initializes a new instance with a specified Query.

Initializes a new instance with a specified Query and TimeObserver. The filter is ready to be used immediately after it is constructed.

Gets or sets the entity parameter placeholder in the Query. ApplyChanges(EvaluatorGroup) must be called after setting this property in order for the change to take effect.

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 a value indicating whether the methods on this instance are safe to call from multiple threads simultaneously.

Gets the set of entities that match this filter.

Gets or sets the AccessQuery. Only entities for which this query returns AccessExists will be matched by this filter. ApplyChanges(EvaluatorGroup) must be called after setting this property in order for the change to take effect. If this query is a composite query (such as AccessQueryAnd), it is usually necessary to have its TimeObserver property set to one of the participants in the query. If this query is an AccessConstraint, the TimeObserver property can be .

Gets or sets the IServiceProvider that will be used to evaluate the Query.

Gets or sets the Transaction parameter placeholder in the Query. ApplyChanges(EvaluatorGroup) must be called after setting this property in order for the change to take effect.

Applies the changes to this filter. This method must be called after setting the Query, TransactionParameter, or EntityParameter properties in order for the changes to take effect. It is also necessary to call this method after changing any of the objects referenced directly or indirectly by these properties. Changes will take effect the next time after calling this method that entities are redistributed within the filter chain with a call to RedistributeEntities.

Indicates to the filter that the EntityFilterChainTEntity has begun matching entities to filters as part of a RedistributeEntities operation.

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.

Indicates to the filter that the EntityFilterChainTEntity has finished matching entities to filters as part of a RedistributeEntities operation.

Allows the filter to perform any filter-specific cleanup at the end of entity matching. This method is called by EndEntityMatching(Transaction).

Allows the filter to perform any filter-specific setup at the start of entity matching. This method is called by BeginEntityMatching(Transaction).

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.

Serves as the default hash function.

Gets the Type of the current instance.

Returns true if the provided entity fits the filter criteria.

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

Checks an entity against this filter and adds it to the MatchingEntities collection if it matches.

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.

Returns a string that represents the current object.
