Function Documentation

acceptVisitor()

template<class T , class V >

void acceptVisitor	(	T	aObject,
		V	aVisitor
	)

Used by SHAPE_INDEX to implement Accept().

By default relies on V::operation() redefinition, should be specialized if V class doesn't have its () operation defined to accept T objects.

Parameters

aObject	is a generic T object.
aVisitor	is a visitor object.

Definition at line 97 of file shape_index.h.

{
 aVisitor( aObject );
}

boundingBox()

template<class T >

BOX2I boundingBox

(

T

aObject

)

Used by SHAPE_INDEX to get the bounding box of a generic T object.

By default relies on T::BBox() method, should be specialized if the T object doesn't allow that method.

Parameters

aObject

is a generic T object.

Returns

a BOX2I object containing the bounding box of the T object.

Definition at line 77 of file shape_index.h.

{
 BOX2I bbox = shapeFunctor( aObject )->BBox();
 
 if( holeFunctor( aObject ) )
 bbox.Merge( holeFunctor( aObject )->BBox() );
 
 return bbox;
}

collide()

template<class T , class U >

bool collide	(	T	aObject,
		U	aAnotherObject,
		int	aMinDistance
	)

Used by SHAPE_INDEX to implement Query().

By default relies on T::Collide(U) method, should be specialized if the T object doesn't allow that method.

Parameters

aObject	is a generic T object.
aAnotherObject	is a generic U object.
aMinDistance	is the minimum collision distance.

Returns

true if object and anotherObject collide.

Definition at line 114 of file shape_index.h.

{
 return shapeFunctor( aObject )->Collide( aAnotherObject, aMinDistance );
}

holeFunctor()

template<class T >

static const SHAPE * holeFunctor ( T  aItem )

static

Used by SHAPE_INDEX to get a SHAPE* for a hole from another type.

By default relies on T::GetHole() method, should be specialized if the T object doesn't allow that method.

Parameters

aItem

generic T object.

Returns

a SHAPE* object equivalent to object.

Definition at line 62 of file shape_index.h.

 return aItem->Hole();

queryCallback()

template<class T , class V >

bool queryCallback	(	T	aShape,
		void *	aContext
	)

Definition at line 120 of file shape_index.h.

{
 V* visitor = (V*) aContext;
 
 acceptVisitor<T, V>( aShape, *visitor );
 
 return true;
}

shapeFunctor()

template<class T >

static const SHAPE * shapeFunctor ( T  aItem )

static

Used by SHAPE_INDEX to get a SHAPE* from another type.

By default relies on T::GetShape() method, should be specialized if the T object doesn't allow that method.

Parameters

aItem

generic T object.

Returns

a SHAPE* object equivalent to object.

Definition at line 47 of file shape_index.h.

{
 return aItem->Shape();
