Открытые методы

Метод	Описание
AddExtension ( object ext ) : void	Adds a new extension.
AddItem ( DataRow row ) : void	Add an item to the layer
AddItem ( object values ) : void	Add an item to the Layer
Clear ( ) : void	Remove all items in the layer
Dispose ( ) : void	Dispose the layer
Draw ( esriDrawPhase drawPhase, IDisplay Display, ITrackCancel trackCancel ) : void	Draws the layer to the specified display for the given draw phase. This method draws the layer to the Display for the specified DrawPhase. Use the TrackCancel object to allow the drawing of the layer to be interrupted by the user.
DrawImmediate ( IGlobeViewer pGlobeViewer ) : void	For custom OpenGL layers, perform immediate drawing. This is where you should add your drawings on the Globe. This method must be overridden in your inheriting class. DrawImmediate together with IGlobeDisplayEvents::BeforeDraw and IGlobeDisplayEvents::AfterDraw is the only safe place where the OpenGL state is ready for custom actions.
GetClassID ( System.Guid &pClassID ) : void	Returns the class identifier (CLSID) for the component object.
GetEnumerator ( ) : IEnumerator	Allow users to directly enumerate through the layer's records
GetSizeMax ( _ULARGE_INTEGER &pcbSize ) : void	Return the size in bytes of the stream needed to save the object.
GetTile ( int tilesize, int face, int level, int row, int col, byte &pData ) : void	Gets a rasterized data tile for the given globe tesselation coordinates.
GlobeCustomLayerBase ( ) : System	Class default constructor
Hit ( int hitObjectID, ESRI pHit3D ) : void	The layer is hit by a picking operation.
IsDirty ( ) : void	Checks the object for changes since it was last saved.
Load ( IStream pstm ) : void	Initializes an object from the stream where it was previously saved.
Load ( IVariantStream Stream ) : void	Loads the object properties from the stream. The Load method must read the data from the stream in the same order the data was written to the stream in the Save method. Streams are sequential; you must ensure that your data is saved and loaded in the correct order, so that the correct data is written to the correct member.
NewItem ( ) : DataRow	Create a new item (does not add it to the layer)
RemoveExtension ( int Index ) : void	Removes the specified extension.
RemoveItem ( DataRow row ) : void	Remove the item from the layer
Save ( IStream pstm, int fClearDirty ) : void	Saves an object into the specified stream and indicates whether the object should reset its dirty flag.
Save ( IVariantStream Stream ) : void	Saves the object properties to the stream.
Select ( string queryFilter ) : System.Data.DataRow[]	Query for items in the layer
get_Extension ( int Index ) : object	The extension at the specified index.
get_LegendGroup ( int Index ) : ILegendGroup	Legend group at the specified index. The content and number of legend groups is determined by the implementation of the renderer, consequently this property is read only.
get_TipText ( double X, double Y, double Tolerance ) : string	Map tip text at the specified location.
this ( int index ) : DataRow	Indexer, returns the underlying DataRow for the given index
