TailPinnedEventArgs Class
Visual Studio 2010
Provides data for the TailPinned event. This class cannot be inherited.
Assembly: System.IO.Log (in System.IO.Log.dll)
The TailPinnedEventArgs type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
The TailPinned event can be fired when the record sequence has run out of space. When this event is fired, the tail of the sequence (that is, the base sequence number) is moved forward to free up space.
This example shows how to use the TailPinned event to free up space in a log sequence.
recordSequence.RetryAppend = true;
recordSequence.TailPinned += new EventHandler<TailPinnedEventArgs>(HandleTailPinned);
void HandleTailPinned(object sender, TailPinnedEventArgs tailPinnedEventArgs)
{
// tailPinnedEventArgs.TargetSequenceNumber is the target
// sequence number to free up space to.
// However, this sequence number is not necessarily valid. We have
// to use this sequence number as a starting point for finding a
// valid point within the log to advance toward. You need to
// identify a record with a sequence number equal to, or greater
// than TargetSequenceNumber; let's call this
// realTargetSequenceNumber. Once found, move the base
recordSequence.AdvanceBaseSequenceNumber(realTargetSequenceNumber);
