void	forEachSubdirection (const Vector3< cell_idx_t > mainDirection, const std::function< void(Vector3< cell_idx_t >) > &func)
	Iterates all sub-directions of a given direction vector and runs a callback on each of them.
bool	forEachSubdirectionCancel (const Vector3< cell_idx_t > mainDirection, const std::function< bool(Vector3< cell_idx_t >) > &func)
	Iterates all sub-directions of a given direction vector and runs a callback on each of them.

template<typename Stencil_T >

void walberla::lbm_generated::util::forEachOrthogonalDirection ( Vector3< cell_idx_t > d, std::function< void(Vector3< cell_idx_t >) > func )

inline

Iterates all directions orthogonal to d that are part of the given stencil, and executes a function on each of them.

Template Parameters

Stencil_T

The underlying stencil

Parameters

d
func

forEachSubdirection()

void walberla::lbm_generated::util::forEachSubdirection ( const Vector3< cell_idx_t > mainDirection, const std::function< void(Vector3< cell_idx_t >) > & func )

inline

Iterates all sub-directions of a given direction vector and runs a callback on each of them.

Subdirections are any nonzero directions obtained by truncating zero or more components of a direction vector to zero. The direction vector itself is contained in this set.

Parameters

mainDirection	The direction whose subdirections will be iterated
func	The callback that should be run for each subdirection

forEachSubdirectionCancel()

bool walberla::lbm_generated::util::forEachSubdirectionCancel ( const Vector3< cell_idx_t > mainDirection, const std::function< bool(Vector3< cell_idx_t >) > & func )

inline

Iterates all sub-directions of a given direction vector and runs a callback on each of them.

Subdirections are any nonzero directions obtained by truncating zero or more components of a direction vector to zero. The direction vector itself is contained in this set.

Parameters

mainDirection	The direction whose subdirections will be iterated
func	The callback that should be run for each subdirection. If the callback returns false, the iteration will be stopped.

Returns

true if the iteration completed, false if it was canceled

getSubdirections()

void walberla::lbm_generated::util::getSubdirections ( const Vector3< cell_idx_t > mainDirection, std::vector< Vector3< cell_idx_t > > subdirs )
