	AbortTransaction	Call the UndoManager's GoUndoManager.AbortTransaction method.
	Add	Add an object to the DefaultLayer, or to the LinksLayer if the object is an IGoLink.
	AddCopy	Add a copy of an object into this document at the given point.
	BeginUpdateViews	Cause all views to stop painting.
	CanCopyObjects	Called to see if the user can copy selected objects in this document.
	CanDeleteObjects	Called to see if the user can delete selected objects in this document.
	CanEditObjects	Called to see if the user can edit objects in this document.
	CanInsertObjects	Called to see if the user can insert objects in this document.
	CanLinkObjects	Called to see if the user can link objects in this document.
	CanMoveObjects	Called to see if the user can move selected objects in this document.
	CanRedo	This predicate is true if this document has an UndoManager whose CanRedo predicate is true.
	CanReshapeObjects	Called to see if the user can reshape resizable objects in this document.
	CanResizeObjects	Called to see if the user can resize selected objects in this document.
	CanSelectObjects	Called to see if the user can select objects in this document.
	CanUndo	This predicate is true if this document has an UndoManager whose CanUndo predicate is true.
	ChangeValue	This method is called by GoChangedEventArgs in order to perform the Undo or Redo or a particular document change.
	Clear	Remove all objects from all layers in this document.
	ComputeBounds	Overloaded. Get the smallest rectangle that includes the bounds of all of the objects in a collection.
	Contains	Determine if an object belongs to this document.
	Copy	Make a copy of this document.
	CopyArray	Gets a newly allocated array of all of the GoObjects in this collection.
	CopyFromCollection	Overloaded. Make copies of a collection of objects in this document.
	CopyNewValueForRedo	This is called during the construction of a GoChangedEventArgs in order to record the newer/next value for a document change.
	CopyOldValueForUndo	This is called during the construction of a GoChangedEventArgs in order to record the older/previous value for a document change.
	CopyTo	Copy references to all of the document objects into the given array of GoObjects.
	CreateCopyDictionary	Allocate a GoCopyDictionary for use in a call to CopyFromCollection(IGoCollection,Boolean,Boolean,SizeF,GoCopyDictionary)
	DoDelayedRouting	Call IGoRoutable.CalculateRoute on each of the objects in the DelayedRoutings collection, and clear that collection.
	EndUpdateViews	Cause all views to continue painting normally.
	EnsureUniquePartID	Make sure every IGoIdentifiablePart in this document has a unique IGoIdentifiablePart.PartID.
	FindNode	Overloaded. Search this document for an object whose IGoLabeledPart.Text property matches a given string, possibly considering the initial part of the part's text string and possibly comparing in a case-insensitive manner.
	FindPart	Returns an IGoIdentifiablePart in this document with the given ID.
	FinishTransaction	Call the UndoManager's GoUndoManager.FinishTransaction method.
	GetAvoidableRectangle	Return the effective bounds of an object that should be avoided when routing links whose GoLink.AvoidsNodes property is true.
	GetEnumerator	Get an Enumerator that iterates over all layers to include all document objects.
	InvalidateViews	Cause all views to completely repaint sometime in the future.
	IsAvoidable	This predicate determines whether the given object is considered when trying to route links whose GoLink.AvoidsNodes property is true.
	IsUnoccupied	Returns true if there are any "avoidable" objects within or intersecting the given rectangular region.
	MakesDirectedCycle	This method returns true if adding a link from a to b would result in a cycle of directed links going through the node a.
	MakesDirectedCycleFast	This method returns true if adding a link from a to b would result in a cycle of directed links going through the node a.
	MakesUndirectedCycle	This method returns true if adding a link from a to b would result in a cycle or loop of links, regardless of link direction, going through the node a.
	MergeLayersFrom	Make sure this document has all of the identified layers of another document.
	PickObject	Find the top-most (front-most) document object at a given point.
	PickObjects	Return a collection of objects that can be picked at a particular point.
	PickObjectsInRectangle	Return a collection of objects that are surrounded by a given rectangle.
	RaiseChanged	Any change to a document or to a part of a document may call this method to invoke the OnChanged method, after the change has occurred.
	RaiseChanging	Call this method to invoke the OnChanged method before any change occurs.
	Redo	Call the UndoManager's GoUndoManager.Redo method if CanRedo is true.
	Remove	Remove an object from this document.
	SetModifiable	This method sets some properties that determine whether the user can modify the document from any view.
	StartTransaction	Call the UndoManager's GoUndoManager.StartTransaction method.
	TestSerialization	Test serializing and deserializing this document, to help discover unserializable objects by getting `SerializationException`s when debugging serialization errors such as during a copy-and-paste.
	Undo	Call the UndoManager's GoUndoManager.Undo method if CanUndo is true.
	UpdateDocumentBounds	Called when a document object's bounds changes to possibly update the document's bounds.
	UpdateRoute	If SuspendsRouting is true add the given IGoRoutable GoObject to the DelayedRoutings collection; otherwise just call CalculateRoute immediately.
	UpdateViews	Cause all views to repaint their invalidated areas.
