Protected Overridable Sub Clear

Classes that are derived from the StaticSiteMapProvider class can override the Clear method to perform additional cleanup, depending on what state the derived classes maintain.

The Clear method does not reset state that is initialized during the Initialize method—it resets only state that is initialized during the BuildSiteMap method.

The following code example demonstrates how to override the Clear method to perform additional cleanup of state that is maintained by the class.

This code example is part of a larger example provided for the StaticSiteMapProvider class.

' SiteMapProvider and StaticSiteMapProvider methods that this derived class must override.
'
' Clean up any collections or other state that an instance of this may hold.
Protected Overrides Sub Clear()
    SyncLock Me
        aRootNode = Nothing
        MyBase.Clear()
    End SyncLock
End Sub 'Clear
