EntityFilterTEntity Class

The base class for classes that are used with EntityFilterChainTEntity to filter entities into different EntitySets based on their properties.
Inheritance Hierarchy

Namespace:  AGI.Foundation.Tracking
Assembly:  AGI.Foundation.Tracking (in AGI.Foundation.Tracking.dll) Version: 24.2.419.0 (24.2.419.0)
Syntax
Copy
public abstract class EntityFilter<TEntity> : DefinitionalObject, 
	IThreadAware, ICloneWithContext
where TEntity : class, IEntityIdentifier

Type Parameters

TEntity
The type of entity.

The EntityFilterTEntity type exposes the following members.

Constructors
Properties
  NameDescription
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.)
Public propertyIsThreadSafe
Gets a value indicating whether the methods on this instance are safe to call from multiple threads simultaneously.
Public propertyMatchingEntities
Gets the set of entities that match this filter.

Methods
  NameDescription
Public methodBeginEntityMatching
Indicates to the filter that the EntityFilterChainTEntity has begun matching entities to filters as part of a RedistributeEntities operation.
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).)
Protected methodCheckForSameDefinition(EntityFilterTEntity)
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).
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 methodEndEntityMatching
Indicates to the filter that the EntityFilterChainTEntity has finished matching entities to filters as part of a RedistributeEntities operation.
Protected methodEntityMatchingCleanup
Allows the filter to perform any filter-specific cleanup at the end of entity matching. This method is called by EndEntityMatching(Transaction).
Protected methodEntityMatchingSetup
Allows the filter to perform any filter-specific setup at the start of entity matching. This method is called by BeginEntityMatching(Transaction).
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.)
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 methodGetDefinitionHashCode
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodIsMatch
Returns true if the provided entity fits the filter criteria.
Public methodIsSameDefinition
Determines if this object has the same definition as another object.
(Inherited from DefinitionalObject.)
Public methodMatch
Checks an entity against this filter and adds it to the MatchingEntities collection if it matches.
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
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 methodToString
Returns a string that represents the current object.
(Inherited from Object.)
