Detailed Description

A parent of all refinement selectors. Abstract class.

All refinement selectors have to derive from this class or its children. The interface of the class provides methods for:

RefinementSelectors::Selector::Selector ( int max_order = H2DRS_DEFAULT_ORDER ) [inline]

Constructor.

Parameters:

[in] max_order A maximum order used by this selector. If it is H2DRS_DEFAULT_ORDER, a maximum supported order is used.

virtual RefinementSelectors::Selector::~Selector ( ) [inline, virtual]

Destructor.

virtual void RefinementSelectors::Selector::generate_shared_mesh_orders	(	const Element *	element,
		const int	orig_quad_order,
		const int	refinement,
		int	tgt_quad_orders[H2D_MAX_ELEMENT_SONS],
		const int *	suggested_quad_orders
	)			`[pure virtual]`

Generates orders of elements which will be created due to a proposed refinement in another component that shares the same a mesh.

Parameters:

`[in]`	element	An element which is about the be refined.
`[in]`	orig_quad_order	An encoded order of the element.
`[in]`	refinement	A refinement of the element in the mesh. Possible values are defined by the enum RefinementType.
`[out]`	tgt_quad_orders	Generated encoded orders.
`[in]`	suggested_quad_orders	Suggested encoded orders. If not NULL, the method should copy them to the output. If NULL, the method have to calculate orders.

virtual bool RefinementSelectors::Selector::select_refinement	(	Element *	element,
		int	quad_order,
		Solution *	rsln,
		ElementToRefine &	refinement
	)			`[pure virtual]`

Selects a refinement.

This methods has to be implemented.

Parameters:

`[in]`	element	An element which is being refined.
`[in]`	quad_order	An encoded order of the element.
`[in]`	rsln	A reference solution which is used to select a refinement.
`[out]`	refinement	A selected refinement. It contains a valid contents if and only if the method returns true.

Returns:: True if a refinement was proposed. False if the selector is unable to select a refinement or it suggest that the element should not be refined.

A maximum allowed order.
