Class PropertyChanges

PropertyChanges is a class for managing property subscriptions both global and per instance. Global(Un)Subscribe methods may be used for global subscriptions (for all-instances) and FirePropertyChanged(INotifyPropertyChangedInvoker, String, Object, Object) should be used to fire both per-instance and global PropertyChanged events. Usually used in conjunction with Fody PropertyChangedNotificationInterceptor.Intercept which may be implemented as:

public static class PropertyChangedNotificationInterceptor2
{
    public static void Intercept(INotifyPropertyChangedInvoker invoker, string propertyName, object? before, object? after) => PropertyChanges.FirePropertyChanged(invoker, propertyName, before, after);
}

Read more about property changes in README.md.

Methods

FirePropertyChanged(INotifyPropertyChangedInvoker, MemberChangedBeforeAfterEventArgs)

Fires both per-instance (using InvokePropertyChanged) and global property change events.

Declaration

public static void FirePropertyChanged(this INotifyPropertyChangedInvoker invoker, MemberChangedBeforeAfterEventArgs args)

Parameters

Type	Name	Description
INotifyPropertyChangedInvoker	invoker
MemberChangedBeforeAfterEventArgs	args

FirePropertyChanged(INotifyPropertyChangedInvoker, String, Object, Object)

Fires both per-instance (using InvokePropertyChanged) and global property change events. If before and after both null it assumes that no before/after values available.

Declaration

public static void FirePropertyChanged(this INotifyPropertyChangedInvoker invoker, string propertyName, object before, object after)

Parameters

Type	Name	Description
INotifyPropertyChangedInvoker	invoker
System.String	propertyName
System.Object	before
System.Object	after

FirePropertyChanged(Object, MemberChangedBeforeAfterEventArgs)

If source is INotifyPropertyChangedInvoker then invokes InvokePropertyChanged which fires per-instance property changes. Anyway fires global property change events.

Declaration

public static void FirePropertyChanged(this object source, MemberChangedBeforeAfterEventArgs args)

Parameters

Type	Name	Description
System.Object	source
MemberChangedBeforeAfterEventArgs	args

FirePropertyChanged(Object, String)

If source is INotifyPropertyChangedInvoker then invokes InvokePropertyChanged which fires per-instance property changes. Anyway fires global property change events.

Declaration

public static void FirePropertyChanged(this object source, string propertyName)

Parameters

Type	Name	Description
System.Object	source
System.String	propertyName

FirePropertyChanged(Object, String, Object, Object)

If source is INotifyPropertyChangedInvoker then invokes InvokePropertyChanged which fires per-instance property changes. Anyway fires global property change events.

Declaration

public static void FirePropertyChanged(this object source, string propertyName, object before, object after)

Parameters

Type	Name	Description
System.Object	source
System.String	propertyName
System.Object	before
System.Object	after

GlobalUnsubscribe(Type, PropertyChangedBeforeAfterEventHandler)

Unsubscribes from all notified properties changes on all instances of type.

Declaration

Declaration

public static void GlobalUnsubscribe(Type type, string propertyName, PropertyChangedBeforeAfterEventHandler action)

Parameters

Type	Name	Description

PropertyChangedBeforeAfterEventHandler	action

IsNotifyingProperty(PropertyInfo)

Return true if the property has an attribute that will make it notify through fody.

Declaration
