Méthodes publiques

Méthode Description
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
