Member Function Documentation

short_t direction ( ) const

inline

Returns the parametric direction orthogonal to this side.

Returns

Integer which says which parameter has to be fixed in order to get the boundary.

Example:
In 2D, let the parameter domain be defined by \((u,v)\in [0,1]^2\). Since the side with index 3 corresponds to "south", i.e. to \( \{ (u,v):\ v = 0 \} \), calling parameter(3) will return 1, because v (i.e., parameter direction with index 1) is fixed/set to zero.

void getContainedCorners	(	short_t	dim,
		std::vector< boxCorner > &	corners
	)		const

returns the vector of the corners contained in the side

Parameters

dim	is the ambient dimension
corners

static boxSide getEnd ( short_t  dim )

inlinestatic

helper for iterating on sides of an n-dimensional box

Parameters

dim

Returns

the (invalid) side after the last one in dim-dimensional box

static boxSide getFirst ( short_t  )

inlinestatic

helper for iterating on sides of an n-dimensional box

Returns

the first valid side in an dim-dimensional box

static boxSide getLast ( short_t  dim )

inlinestatic

helper for iterating on sides of an n-dimensional box

Parameters

dim

Returns

the last valid side in an dim-dimensional box

boxSide opposite ( ) const

inline

returns the parallel opposite side

Returns

bool parameter ( ) const

inline

Returns the parameter value (false=0=start, true=1=end) that corresponds to this side.

Returns

false, if side s is defined by setting the corresponding parameter to 0, and
true, if it is defined by setting the corresponding parameter to 1.

Example:
In 2D, let the parameter domain be defined by \((u,v)\in [0,1]^2\). Since the side with index 3 corresponds to "south", i.e. to \( \{ (u,v):\ v = 0 \} \), calling parameter(3) will return 0=false.
