Detailed Description

template<class GridInspector, class CreativeObject = void>
struct Wizt::GridActor< GridInspector, CreativeObject >

Creator for objects operating on certain kinds of Grid objects, providing an interface for the function Fiber::hasProperty() .

This template class provides a VCreator which requires input objects to provide Fiber::Grid objects that fulfull certain conditions, such as being a triangular surface or a set of lines.

Such conditions are formulated as a Fiber::BundleProperty, this template is a convenience helper class for VCreator objects that maps BundleProperty objects to VCreator acceptance functions.

For instance, one possible property to look for in a Grid object is the existence of a specific Skeleton. This property is modeled via a SkeletonExistence object. Code for objects operating on LineSets would look like this:

struct  LineSetOperationObject;
 
struct  MyGridInspector
{
static  SkeletonExistence      InspectionProperty()
        {
                return SkeletonExistence( LineSet::ID() );
        }
};
 
static  Ref<GridActor<MyGridInspector, LineSetOperationObject> >
        VLineSetOperationObjectCreator("Demo/LineSetOperationObject", ObjectQuality::DEMO);

Note that the function MyGridInspector::InspectionProperty() may return any object that is derived from class Fiber::BundleProperty and is accepted by Fiber::hasProperty(). For instance, a generic property may be defined as

struct  MyGridInspector
{
        struct  MyProperty : Fiber::BundleProperty
        {
                bool checkSlice(Slice&S, const string&GridName) const override
                {
                ...
                }
        };
 
static  MyProperty&InspectionProperty()
        {
        static  MyProperty myProperty;
                return myProperty;
        }
};

To generically check for a specific Grid derive from the GridProperty class:

struct  MyGridInspector
{
        struct  MyProperty : Fiber::GridProperty
        {
                bool checkGrid(const Grid&G) const override
                {
                        return true;
                }
        };
 
static  const MyProperty&InspectionProperty()
        {
        static  MyProperty myProperty;
                return myProperty;
        }
};

Note: User code may #define VERBOSE_GRIDACTOR prior to any header file inclusion to enable printing of some informative messages when the GridActor evaluates objects and tries to find out if there is a match.
