The StreamChain type exposes the following members.

Properties

	Name	Description
	Access	Gets the type of access that is permitted to the chain. (Inherited from RootChain.)
	AfterLastToken	Gets an EventToken for the position that is immediately after the current LastToken. (Overrides Chain.AfterLastToken.)
	BeforeFirstToken	Gets an EventToken for the position that is immediately before FirstToken. (Inherited from Chain.)
	CanGetCount	Gets a value that determines whether the chain supports Count. (Inherited from Chain.)
	CanGetLastToken	Gets a value that determines whether the chain supports LastToken. (Inherited from Chain.)
	CanGetPreviousToken	Gets a value that determines whether the chain supports GetPreviousToken. (Inherited from Chain.)
	Count	Gets the number of events in the chain. (Inherited from Chain.)
	FirstToken	Gets an EventToken for the first event in the chain. (Overrides Chain.FirstToken.)
	FirstValidToken	Gets an EventToken for the first valid event in the chain. (Overrides Chain.FirstValidToken.)
	IsEmpty	Gets a value that indicates whether the chain is empty. (Overrides Chain.IsEmpty.)
	LastToken	Gets an EventToken for the last event in the chain. (Inherited from Chain.)

Methods

	Name	Description
	AppendEvent	Appends an IntelliTraceEvent to a stream. (Overrides RootChain.AppendEvent(IntelliTraceEvent).)
	ConvertToBytes	When overridden in a derived class, converts an IntelliTraceEvent to a raw event.
	ConvertToEvent	When overridden in a derived class, converts a raw event to an IntelliTraceEvent.
	Dispose()	(Inherited from Chain.)
	Dispose(Boolean)	Releases the resources that are used by this chain. (Overrides Chain.Dispose(Boolean).)
	Equals	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.)
	GetEvent	Gets an IntelliTraceEvent for the specified EventToken. (Overrides Chain.GetEvent(EventToken).)
	GetEvents	Gets multiple IntelliTraceEvents from a start EventToken up to but excluding an end EventToken. (Overrides Chain.GetEvents(EventToken, EventToken).)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetNextToken	Gets the EventToken for the next event after the given EventToken. (Overrides Chain.GetNextToken(EventToken).)
	GetPreviousToken	Gets the EventToken for the previous event before the given EventToken. (Inherited from Chain.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsValidEventType	When overridden in a derived class, determines whether the given IntelliTraceEvent is valid for this chain. (Inherited from Chain.)
	IsValidToken	Determines whether the given EventToken is valid for this chain. (Overrides Chain.IsValidToken(EventToken).)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ReadEventBytes	When overridden in a derived class, reads a single raw event from the stream.
	ReadEventLength	When overridden in a derived class, gets the length of the next event in the stream.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

StreamChain provides on-demand access and instantiation of events in the stream when GetEvent or GetEvents is called. IntelliTraceEvents are not stored by the StreamChain.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
