Specialist data layer for the handling of user drawn data.
The Custom Data Layer allows the developer to get a handle to the TSLRenderingInterface class, thus enabling custom drawing in the drawing surface. The Custom Data Layer also allows for additional MapLink data layers to be drawn as part of the Custom Data Layer itself via an instance of the TSLCustomDataLayerHandler class.
The developer should at minimum derive from TSLClientCustomDataLayer in the application and implement the pure virtual drawLayer method. Additional methods on TSLClientCustomDataLayer may be overridden as necessary.
When using a Custom Data Layer within a drawing surface from the 3D SDK or Accelerator SDK the developer should ensure that the layer implementation is thread safe. If the data layer implementation is not thread safe a Custom Data Layer must not be shared between multiple drawing surfaces under any circumstances.
Note: If you are not using the version of Visual Studio that MapLink was built with then you need to manage the deletion of the TSLClientCustomDataLayer derived object yourself.

Constructor for TSLCustomDataLayer.
Construct this class on the heap and use destroy() to delete it.
|

Destructor for TSLCustomDataLayer.
This is declared as protected to prevent developers from creating this on the stack. The destroy() method should be used to remove instances of this class.
|

| TSLClientCustomDataLayer * TSLCustomDataLayer::getClientCustomDataLayer | ( | ) |
Returns the client custom data layer instance attached to this TSLCustomDataLayer.
| const TSLClientCustomDataLayer * TSLCustomDataLayer::getClientCustomDataLayer | ( | ) | const |
Returns the client custom data layer instance attached to this TSLCustomDataLayer.

Allocation override for API redirection
| void * TSLCustomDataLayer::operator new | ( | size_t | size, |

| int | line ) |
When included in an MFC application in debug mode, the debug new expects this to be here. Override it and return the same as the normal one. The library must include it when compiled in release mode, since the user's application may be in debug mode.
|
protected |
Assignment operator.
Sets the custom data layer to be equal to that specified.
| customDataLayer | Source for new custom data layer. |
| void TSLCustomDataLayer::setClientCustomDataLayer | ( | TSLClientCustomDataLayer * | client, |
| bool | ownsClient = false ) |
Attaches an instance of TSLClientCustomDataLayer to the TSLCustomDataLayer.
This should be used to attach a handle to the developers TSLClientCustomDataLayer derived class.
| client | A pointer to a TSLClientCustomDataLayer derived class. |
| ownsClient | Indicates whether the TSLCustomDataLayer owns the client. If true the attached TSLClientCustomDataLayer will be deleted when the TSLCustomDataLayer is destroyed. The default value is false. |
| bool TSLCustomDataLayer::valid | ( | ) | const |
Checks if a TSLClientCustomDataLayer pointer has been attached to the class.
Returns true if it has, false otherwise.
