LVectorLayer

Description

The LVectorLayer class is used in conjunction with the main vector class LVectorBase and the vector object class LVectorObject. This class contains the functionality for dealing with vector layers, This class contains functions for the following:

• Enumerating the vector objects in a vector layer
• Removing the vector objects in a vector layer
• Copying a vector layer to another vector
• Getting information about a vector layer
• Adding objects to a vector layer
• Returning count of objects in a vector layer

When calling some functions of the LVectorLayer class, the associated vector data is changed. To be notified of these changes, you can override the LVectorBase::StartChanging and LVectorBase::EndChanging functions. For more information, refer to Bitmap and Vector Change Notifications and Notification Categories.

If you derive a class from LVectorLayer, the macros defined in Wrapper Macros may be helpful.
