Methods

	Name	Description
	AccumulateChangeData	Accumulates the change data of the child. Currently only a flag is set to signal that the table has changed. (Inherited from TableDataSourceBase)
	AccumulatedChangeData_SetBackAfterResumeAndSuspend	Sets the change data without further processing. This function is infrastructure and intended to use only in OnResume after the parent has suspended this node again. (Inherited from SuspendableDocumentNodeWithSingleAccumulatedDataT)
	AccumulatedEventData_Clear	Clears the accumulated event data. (Inherited from SuspendableDocumentNodeWithSingleAccumulatedDataT)
	AccumulatedEventData_HasZeroOrOneEventArg	Determines whether there is no or only one single event arg accumulated. If this is the case, the return value is true. If there is one event arg accumulated, it is returned in the argument singleEventArg. The return value is false if there is more than one event arg accumulated. In this case the singleEventArg is null on return, and the calling function should use AccumulatedEventData to enumerate all accumulated event args. (Inherited from SuspendableDocumentNodeWithSingleAccumulatedDataT)
	ChildCloneFromT	Clones a node that is intended to use as child node of this instance (e.g. in collections). Consider using ChildCloneToMemberT(T, T) instead if the child node is stored in a member of this instance. (Inherited from SuspendableDocumentNode)
	ChildCloneToMemberT	Sets a member variable that holds a child with a cloned instance of another variable. If an old instance member (provided in myChild exists and can not be used, it is disposed first. The node is then cloned using System.ICloneable. The resulting node's ParentObject is then set to this instance in order to maintain the parent-child relationship. (Inherited from SuspendableDocumentNode)
	ChildCloneToMemberAltT	Set a member variable that holds a child node of this instance. The child node may or may not implement IDocumentLeafNode. The value to set may or may not implement ICloneable. If it implements ICloneable, then the member variable is set to a clone of the value. Otherwise, the member variable is set directly with the value. It helps to ensure the correct order: first, the child node is set to the new instance and then the old child node is disposed. (Inherited from SuspendableDocumentNode)
	ChildCopyToMemberT	Copies a document node from another source into a member of this instance. If an old instance member (provided in myChild exists and can not be used, it is disposed first. The node is then copied using either Main.ICopyFrom or System.ICloneable. The resulting node's ParentObject is then set to this instance in order to maintain the parent-child relationship. (Inherited from SuspendableDocumentNode)
	ChildCopyToMemberOrCreateNewT	Copies a document node from another source into a member of this instance. If an old instance member (provided in myChild exists and can not be used, it is disposed first. If the node is not null, the node is then copied using either Main.ICopyFrom or System.ICloneable. If the node is null, a new node is created using the provided generation function. The resulting node's ParentObject is then set to this instance in order to maintain the parent-child relationship. (Inherited from SuspendableDocumentNode)
	ChildDisposeMemberT	Helper function to dispose a child node of this instance. It helps to ensure the correct order: first, the child node is set to null and only then the child node is disposed. (Inherited from SuspendableDocumentNodeBase)
	ChildSetMemberT	Set a member variable that holds a child node of this instance. It helps to ensure the correct order: first, the child node is set to the new instance and then the old child node is disposed. (Inherited from SuspendableDocumentNode)
	ChildSetMemberAltT	Set a member variable that holds a child node of this instance. The child node may or may not implement IDocumentLeafNode. It helps to ensure the correct order: first, the child node is set to the new instance and then the old child node is disposed. (Inherited from SuspendableDocumentNode)
	Clone	Clones this instance.
	CopyFrom(AltaxoOleDbDataSource)
	CopyFrom(Object)
	CountEvent	Counts the number of events during the suspend state. Every call to this function will increment the event counter by 1 (but only in the suspended state). The event counter will be reset to zero when the object is resumed. (Inherited from SuspendableDocumentNode)
	Dispose	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. (Inherited from SuspendableDocumentNodeBase)
	Dispose(Boolean)	Releases the unmanaged resources used by the AltaxoOleDbDataSource and optionally releases the managed resources (Overrides SuspendableDocumentNodeDispose(Boolean))
	EhChildChanged	Used by childs of this object to inform us about a change in their state. (Inherited from SuspendableDocumentNode)
	EhParentTunnelingEventHappened	Is called by the parent when a tunneling event happened in the parent. (Inherited from SuspendableDocumentNode)
	EhSelfChanged	Called if some (simple) member or property of this instance itself has changed. (Inherited from SuspendableDocumentNode)
	EhSelfTunnelingEventHappened(TunnelingEventArgs)	Is called by this instance if a tunneling event happened into this instance. The tunneling event triggers the TunneledEvent and is additionally distributed to all childs of this instance. (Inherited from SuspendableDocumentNodeBase)
	EhSelfTunnelingEventHappened(TunnelingEventArgs, Boolean)	Is called by this instance if a tunneling event happened into this instance. The tunneling event triggers the TunneledEvent and is - depending on the provided parameter - also distributed to all childs of this instance. (Inherited from SuspendableDocumentNode)
	EnumerateFromHereToLeaves	Enumerates all document node including this node, its child nodes, its child-child nodes up to the leaf nodes. (Inherited from SuspendableDocumentNode)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	FillData	(Inherited from TableDataSourceBase)
	FillData_Unchecked	Fills (or refills) the data. The data source is represented by this instance, the destination table is provided in the argument destinationTable. (Overrides TableDataSourceBaseFillData_Unchecked(DataTable, IProgressReporter))
	Finalize	Finalizes an instance of the SuspendableDocumentNodeBase class. (Inherited from SuspendableDocumentNodeBase)
	GetChildObjectNamed	Retrieves the child node of this instance with the name C# Copy name . (Inherited from SuspendableDocumentNode)
	GetDocumentNodeChildrenWithName	(Overrides SuspendableDocumentNodeGetDocumentNodeChildrenWithName)
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetNameOfChildObject	Gets the name of child node. (Inherited from SuspendableDocumentNode)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	HandleHighPriorityChildChangeCases	Handles the case when a child changes, and a reaction is neccessary independently on the suspend state of the table. (Inherited from SuspendableDocumentNode)
	HandleLowPriorityChildChangeCases	Processes the event args e when this object is not suspended. This function serves two purposes: i) updating some cached data of this object by processing the event args of the child, and ii) optional transforming the event args, for instance to a new type, which afterwards is send to the parent and is used as event args in the [E:Changed] event of this object. The transformed event args is not used if this object is suspended (in this case the original event args is used). (Inherited from SuspendableDocumentNode)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	NotifyChildrenTunnelingEventHappened	Notifies the child nodes of this instance that a tunneling event has happened. (Inherited from SuspendableDocumentNode)
	OnAboutToBeResumed	Is called when the suspend level is still 1 (one), but is about to fall to zero, i.e. shortly before the call to OnResume(Int32). This function is not called before OnResumeSilently(Int32)! (Inherited from SuspendableDocumentNode)
	OnAfterDeserialization
	OnChanged	Fires the change event with the EventArgs provided in the argument. (Inherited from SuspendableDocumentNodeBase)
	OnResume	(Overrides SuspendableDocumentNodeOnResume(Int32))
	OnResumeSilently	Is called when the suspend level falls down from 1 to zero by a call to ResumeSilently. This implementation disarma the suspendTokens of the childs of this object, deletes any accumulated events, and does not send any change event to the parent or the listeners of the Change event. (Inherited from SuspendableDocumentNode)
	OnSuspended	Called when the suspend level has just gone from 0 to 1, i.e. the object was suspended. (Inherited from SuspendableDocumentNode)
	OnTunnelingEvent	Fires the TunneledEvent event. (Inherited from SuspendableDocumentNodeBase)
	Resume(ISuspendToken)	Resumes changed events by calling Resume for the provided suspend token, and setting the reference to the suspend token to null. If Event data were accumulated during the suspended state, a changed event is triggered for each event data. (Inherited from SuspendableDocumentNodeBase)
	Resume(ISuspendToken, EventFiring)	Resumes changed events, either with taking the accumulated event data into account (see Resume(ISuspendToken)) or discarding the accumulated event data (see ResumeSilently(ISuspendToken), depending on the provided argument eventFiring. (Inherited from SuspendableDocumentNodeBase)
	ResumeCompleteTemporarily	Resumes the object completely for only a short time. Thus, if object was suspended before, it will be suspended again when the function returns. (Inherited from SuspendableDocumentNode)
	ResumeCompleteTemporarilyGetToken	Resumes the object completely for the time the returned token is referenced and not disposed. The return value is a token that had 'absorbed' the suspend count of the object, resulting in the suspend count of the object dropped to 0 (zero). When the returned token is finally disposed, the suspend count of the object is increased again by the 'absorbed' suspend count. (Inherited from SuspendableDocumentNode)
	ResumeSilently	Resumes changed events by calling Resume for the provided suspend token, and setting the reference to the suspend token to null. All event data accumulated during the suspended state are discarded, and thus no change event is triggered even if the instance has changed during the suspended state. (Inherited from SuspendableDocumentNodeBase)
	SetDisposeInProgress	Sets the flag that dispose is in progress for this node and all child nodes recursively. (Inherited from SuspendableDocumentNode)
	SetMemberAndRaiseSelfChangedT(NullableT, NullableT)	Sets a member variable of this instance and raise a change event with Empty if the new value is different from the old value. The comparison is done using the IEquatableT interface of the member variable. Note: to set members that implement IDocumentNode please use the Child... functions. (Inherited from SuspendableDocumentNodeBase)
	SetMemberAndRaiseSelfChangedT(T, T)	Sets a member variable of this instance and raise a change event with Empty if the new value is different from the old value. The comparison is done using the IEquatableT interface of the member variable. Note: to set members that implement IDocumentNode please use the Child... functions. (Inherited from SuspendableDocumentNodeBase)
	SetMemberEnumAndRaiseSelfChangedT	Sets a member variable (which is an Enum) of this instance and raise a change event with Empty if the new value is different from the old value. The comparison is done using the IEquatableT interface of the member variable. Note: to set members that implement IDocumentNode please use the Child... functions. (Inherited from SuspendableDocumentNodeBase)
	SuspendGetToken	Suspend will increase the SuspendLevel. (Inherited from SuspendableDocumentNode)
	ToString	Returns a string that represents the current object. (Inherited from Object)
	TryGetName	Test if this item already has a name. (Inherited from SuspendableDocumentNodeBase)
	UpdateWatching
	VisitDocumentReferences
