gsBoxTopology Class Reference

Detailed Description

Defines a topological arrangement of a collection of "boxes" (e.g., parameter domains that map to physical-domain patches).

The information on outer boundaries is stored as a list of patchSide structs, each one defining the corresponding patch side to lie on the boundary.

The topological arrangement is stored as a list of boundaryInterface structs, each one defining an interface between two patch sides.

Member Function Documentation

addBoxProperty()

template<class T >

gsProperty< T > addBoxProperty ( const std::string &  name, T  t = T()  )

inline

Adds a box property.

Parameters

[in]	name	The name of the property
[in]	t	The value of the property

Template Parameters

T	The type of the property

Returns

The property as a gsProperty object

allComponents()

std::vector< std::vector< patchComponent > > allComponents

(

bool

combineCorners = false

)

const

Returns all components representing the topology.

Each entry of the outer vector represents one component (patch-interior, face, edge, corner, etc.). Since the components refering to one interface can be addressed as belonging to different patches, each component itself is represented by an inner vector which contains all patchComponent objects that refer to the particular component.

Parameters

combineCorners

If this is set, all corners are treated as one component

bBegin() [1/2]

biterator bBegin ( )

inline

Get an iterator to the beginning of the boundaries

Returns

an iterator to the beginning of the boundaries

bBegin() [2/2]

const_biterator bBegin ( ) const

inline

Get a const-iterator to the beginning of the boundaries

Returns

an iterator to the beginning of the boundaries

bEnd() [1/2]

biterator bEnd ( )

inline

Get an iterator to the end of the boundaries

Returns

an iterator to the end of the knotvector

bEnd() [2/2]

const_biterator bEnd ( ) const

inline

Get a const-iterator to the end of the boundaries

Returns

an iterator to the end of the boundaries

findInterface()

const boundaryInterface * findInterface	(	const index_t	b1,
		const index_t	b2
	)		const

Returns a pointer to the interface between boxes b1 and b2, if one exists, otherwise it returns a null pointer
