16.2.3 Creating a New Projection Class
You can create a new projection class by deriving a new subclass of the
%Projection.AbstractProjection class, implementing the projection interface methods, and
defining any class parameters you require:
Class MyApp.MyProjection Extends %Projection.AbstractProjection
{
Parameter MYPARM;
/// This method is invoked when a class is compiled
ClassMethod CreateProjection(cls As %String, ByRef params)
{
}
/// This method is invoked when a class is 'uncompiled'
ClassMethod RemoveProjection(cls As %String, ByRef params, deleted as %Boolean)
{
}
}
