ChangeMonitor Constructor

Definition

Namespace:

System.Runtime.Caching

Assembly:

System.Runtime.Caching.dll

Package:

System.Runtime.Caching v9.0.0-preview.3.24172.9

Source:

ChangeMonitor.cs

Initializes a new instance of the ChangeMonitor class. This constructor is called from constructors in derived classes to initialize the base class.

protected:
 ChangeMonitor();

protected ChangeMonitor ();

Protected Sub New ()

Remarks

The ChangeMonitor class has a parameterless constructor. However, classes that inherit from the base ChangeMonitor class and define custom change-monitoring behavior must perform initialization in the constructor. For more information, see the Notes for Inheritors section.

Notes to Inheritors

The constructor of a derived class must set the UniqueId property, begin monitoring, and call the InitializationComplete() class before it returns. If a dependency changes before initialization is complete (for example, if a dependent cache key is not found in the cache), the constructor must call the OnChanged(Object) method before it calls the InitializationComplete() method. In this case, constructor can call the Dispose() method only after the InitializationComplete() method is called, because the Dispose() method throws an exception if initialization is not completed.
