Properties
 NameDescription
Protected propertyAccumulatedEventData Gets the accumulated event data.
(Inherited from SuspendableDocumentLeafNodeWithSingleAccumulatedDataT)
Public propertyAssignVector Provides a setter property to which a vector can be assigned to. Copies all elements of the vector to this column.
Public propertyCount Returns the row count, i.e. the one more than the index to the last valid data element in the column.
Public propertyData Provides a setter property to which another data column can be assigned to. Copies all elements of the other DataColumn to this column. An exception is thrown if the data types of both columns are incompatible. See also CopyDataFrom(Object).
Protected propertyDebug_AbsolutePath Gets the absolute path of the node for debugging purposes.
(Inherited from SuspendableDocumentNodeBase)
Public propertyFullName Returns either the column name if the column has no parent table, or the parent table name, followed by a backslash and the column name if the column has a table.
Public propertyIsDirty Column is dirty if either there are new changed or deleted rows, and no data changed event was fired for notification. This value is reseted after the data changed event has notified the change.
Public propertyIsDisposed Gets a value indicating whether this instance is disposed.
(Inherited from SuspendableDocumentNodeBase)
Public propertyIsDisposeInProgress Gets a value indicating whether for this instance dispose is in progress, or the instance is already disposed.
(Inherited from SuspendableDocumentNodeBase)
Public propertyIsReadOnly 
Public propertyIsSomeoneListeningToChanges Gets a value indicating whether someone is listening to changes. For this, either the ParentObject or the Changed event must be set.
(Inherited from SuspendableDocumentNodeBase)
Public propertyIsSuspended Gets a value indicating whether this instance is suspended.
(Inherited from SuspendableDocumentLeafNode)
Public propertyItem Gets/sets the element at the index i by a value of type AltaxoVariant.
Public propertyItemType Gets the type of the colum's items.
Public propertyName Gets the name of this document node. Null is returned if the name is not set or unknown. The set accessor will for most nodes throw a InvalidOperationException, since the name can only be set on IProjectItems.
(Inherited from SuspendableDocumentNodeBase)
Public propertyParentObject Get / sets the parent object of this data column.
(Overrides SuspendableDocumentNodeBaseParentObject)
Public propertyTypeAndName Returns the column type followed by a backslash and the column name.

Methods
 NameDescription
Protected methodAccumulateChangeData(Object, EventArgs) Accumulates the change data of the child. Currently only a flag is set to signal that the table has changed.
(Overrides SuspendableDocumentLeafNodeWithEventArgsAccumulateChangeData(Object, EventArgs))
Protected methodAccumulateChangeData(Int32, Int32, Boolean) Accumulates the change data provided in the arguments into the m_ChangeData member.

Protected methodAccumulatedEventData_Clear Clears the accumulated event data.
(Inherited from SuspendableDocumentLeafNodeWithSingleAccumulatedDataT)
Protected methodAccumulatedEventData_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.

Protected methodMemberwiseCloneCreates a shallow copy of the current Object.
(Inherited from Object)
Protected methodOnAboutToBeResumed 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)
Protected methodOnChanged Fires the change event with the EventArgs provided in the argument.
(Inherited from SuspendableDocumentNodeBase)
Protected methodOnResume 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)
Protected methodOnResumeSilently 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)
Protected methodOnSuspended Called when the suspend level has just gone from 0 to 1, i.e. the object was suspended.

Public methodResume(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)
Public methodResume(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)
Public methodResumeCompleteTemporarily 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)
Public methodResumeCompleteTemporarilyGetToken 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)
Public methodResumeSilently 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)
Protected methodSetMemberEnumAndRaiseSelfChangedT 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.
