Thetype exposes the following members.
Gets or sets the weaving priority of the aspect.(Inherited from Aspect.)
If true, indicates that this attribute removes all other instances of the same attribute type from the set of elements defined by the current instance.(Inherited from MulticastAttribute.)
Determines whether this attribute is inherited(Inherited from MulticastAttribute.)
Gets or sets the priority of the current attribute in case that multiple instances are defined on the same element (lower values are processed before).(Inherited from MulticastAttribute.)
Determines whether this attribute replaces other attributes found on the target declarations.(Inherited from MulticastAttribute.)
Gets or sets the assemblies to which the current attribute apply.(Inherited from MulticastAttribute.)
Gets or sets the kind of elements to which this custom attributes applies.(Inherited from MulticastAttribute.)
Gets or sets the visibilities, scopes, virtualities, and implementation of members to which this attribute applies, when the member is external to the current module.(Inherited from MulticastAttribute.)
Gets or sets the visibilities of types to which this attribute applies, when this type is external to the current module.(Inherited from MulticastAttribute.)
Gets or sets the visibilities, scopes, virtualities, and implementation of members to which this attribute applies.(Inherited from MulticastAttribute.)
Gets or sets the expression specifying to which members this instance applies.(Inherited from MulticastAttribute.)
Gets or sets the passing style (by value, out or ref) of parameters to which this attribute applies.(Inherited from MulticastAttribute.)
Gets or sets the expression specifying to which parameters this instance applies.(Inherited from MulticastAttribute.)
Gets or sets the visibilities of types to which this attribute applies.(Inherited from MulticastAttribute.)
Gets or sets the expression specifying to which types this instance applies.(Inherited from MulticastAttribute.)
Gets the object to which the current aspect has been applied.(Inherited from InstanceLevelAspect.)
Determines whether the aspect should do additional efforts to prevent the PropertyChanged event from being raised when the value itself did not change. The default value of this property is false, which means that the aspect will raise the PropertyChanged event whenever any dependency of the property has changed, whether the property value has eventually changed or not. Setting this property to true consumes more memory and processing power because the aspect will need to evaluate the properties and store their value.
Method invoked at build time to initialize the instance fields of the current aspect. This method is invoked before any other build-time method.(Overrides TypeLevelAspect.CompileTimeInitialize(Type, AspectInfo).)
Method invoked at build time to ensure that the aspect has been applied to the right target.(Inherited from TypeLevelAspect.)
Method invoked at build time to ensure that the aspect has been applied to the right target.(Overrides TypeLevelAspect.CompileTimeValidate(Type).)
Creates a new instance of the aspect based on the current instance, serving as a prototype.(Overrides InstanceLevelAspect.CreateInstance(AdviceArgs).)
Method invoked at build tome to get the imperative configuration of the current Aspect.(Inherited from Aspect.)
Method called after the an object enhanced by the current aspect has been cloned using MemberwiseClone(). The this parameter refers to the new aspect instance in the cloned object.(Overrides InstanceLevelAspect.OnCloned(ICloneAwareAspect).)
Gets the implementation of a specified interface for the specified object.(Defined by QueryInterfaceExtensions.)
The aspect analyzes dependencies between property getters and fields. The aspect understands indirect dependencies. For instance, a property getter may depend on several other methods or property getters, which in turn can depend on other methods or fields. The algorithm is not able to analyze calls to virtual methods or delegates (because of prohibitive computational cost), and will only try to analyze methods in the current class.
The aspect will emit a build-time error if it is not able to understand the code of the target class. In this case, you can exclude the property from automatic change notification by applying the IgnoreAutoChangeNotificationAttribute custom attribute to the problematic property, or SafeForDependencyAnalysisAttribute to ignore the warnings of the dependency analysis engine. You will then need to specify dependencies explicitly using the Depends class. You can also mark a helper method with the PureAttribute to make it safe from use in a property getter. For instance, the string.Format method is pure.
By default, the true value to the holdWeakReference parameter of constructor.aspect holds strong references to the client delegates. This behavior can cause memory leaks if client delegates are not properly removed before client objects are disposed. To cause the aspect to store weak references, pass the
Target classes can customize the OnPropertyChanged(string) method manually. If this method is implemented, it must be protected or public.aspect by implementing the
By default, the true value to the preventFalsePositives parameter of constructor.aspect does not call property getters by itself in order to avoid unexpected side-effects. However, this means that there are false positive notifications of property change. To allow aspect to use arbitrary calls to property getters to suppress false positives, pass the
