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::IlvMapRenderingStyle

(

IlvDisplay *

display

)

[protected]

The constructor of this abstract class is protected.

Parameters:

display

The display used to create the graphic palettes.

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.

virtual IlvMapRenderingStyle::~IlvMapRenderingStyle

(

)

[protected, virtual]

Destructor.

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