Methods| Name | Description | |
|---|---|---|
 | AccumulateChangeData | (Inherited from SuspendableDocumentLeafNodeWithEventArgs) |
| 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 SuspendableDocumentLeafNodeWithSingleAccumulatedDataT) |
| AccumulatedEventData_Clear |
Clears the accumulated event data.
(Inherited from SuspendableDocumentLeafNodeWithSingleAccumulatedDataT) |
| 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 SuspendableDocumentLeafNodeWithSingleAccumulatedDataT) |
| ChangeParentAnchorButKeepPosition | (Inherited from ItemLocationDirect) |
| ChangeParentAnchorToLeftTopButKeepPosition | (Inherited from ItemLocationDirect) |

(Inherited from SuspendableDocumentNodeBase) |
| Clone | (Overrides ItemLocationDirectClone) |
| CopyFrom | (Overrides ItemLocationDirectCopyFrom(Object)) |
| Dispose |
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

| InternalSetSizeYSilent | (Overrides ItemLocationDirectInternalSetSizeYSilent(RADouble)) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| 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. This function is not called before OnResumeSilently!
(Inherited from SuspendableDocumentLeafNode) |
| OnChanged |
Fires the change event with the EventArgs provided in the argument.
(Inherited from SuspendableDocumentNodeBase) |
| OnResume |
Is called when the suspend level falls down from 1 to zero by a call to Resume or a call to [M:Altaxo.Main.ISuspendToken.Dispose()].
(Inherited from SuspendableDocumentLeafNode) |
| OnResumeSilently |
Is called when the suspend level falls down from 1 to zero by a call to ResumeSilently.
The implementation should delete any accumulated events, should also disarm the suspendTokens of the childs of this object, and should not fire any Changed events nor set the change state of the object to dirty.
(Inherited from SuspendableDocumentLeafNode) |
| OnSuspended |
Called when the suspend level has just gone from 0 to 1, i.e. the object was suspended.
(Inherited from SuspendableDocumentLeafNode) |
| 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 SuspendableDocumentLeafNode) |
| 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 SuspendableDocumentLeafNode) |
| 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) |
| SetAbsolutePivotPosition | (Inherited from ItemLocationDirect) |
| SetAbsoluteSize | (Inherited from ItemLocationDirect) |
| SetDisposeInProgress |
Sets the flag that dispose is in progress for this node and all child nodes recursively.
(Inherited from SuspendableDocumentNodeBase) |
| 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.
