Member Function Documentation

void IlvProjectionClassInfo::addAccessor ( const IlvSymbol name,
IlvValueTypeClass type,
IlvProjectionInterfaceGetter  ,
IlvProjectionInterfaceSetter   
)

Adds an accessor to the projection class.

Accessors are used by the IlvProjectionInterface class to provide run-time information about the parameters of a projection.
The predefined projection interface setter IlvNullProjectionInterfaceSetter should be used for read-only parameters.

Note
For more information about creating an appropriate IlvProjectionClassInfo for a projection class that you have subtyped and adding accessors for the additional parameters, refer to the section "Defining a New Projection".
const char* IlvProjectionClassInfo::getProjectionName ( ) const

Returns the projection name of the class.

For example, the projection name of the class IlvMercatorProjection is "Mercator", and the projection name of the class IlvUniversalTransverseMercator is "Universal Transverse Mercator".

Returns
The projection name.
