Detailed Description

This abstract class is the base class of the rendering styles.

A rendering style is used by the renderers to define the graphic style of the graphic objects representing vector map features. Instances of IlvMapRenderingStyle are shared objects. As a consequence, they should never be deleted. The memory management should be performed using the lock and unLock mechanism. Library: ilvmaps

Constructor & Destructor Documentation

IlvMapRenderingStyle() [1/2]

IlvMapRenderingStyle::IlvMapRenderingStyle ( IlvDisplay *  display )

protected

The constructor of this abstract class is protected.

Parameters

display

The display used to create the graphic palettes.

IlvMapRenderingStyle() [2/2]

IlvMapRenderingStyle::IlvMapRenderingStyle ( const IlvMapRenderingStyle &  source )

protected

Creates a renderer by copying an existing one.

Since this class is abstract, this copy constructor is protected.

Parameters

source

The object to be copied.

~IlvMapRenderingStyle()

virtual IlvMapRenderingStyle::~IlvMapRenderingStyle ( )

protectedvirtual

Destructor.

The destructor of this class is protected, because instances of IlvMapRenderingStyle are potentially shared by several objects.
