Detailed Description

This class implements the "Directional Tiling" tiling method.

In this method the decomposition is done along certain directions of the multi-dimensional cube. The user uses r_Dir_Decompose to inform the system on how the decomposition is done in each dimension.

read everything from encoded string e.g.

◆ r_Dir_Tiling() [2/2]

r_Dir_Tiling::r_Dir_Tiling	(	r_Dimension	dims,

		r_Bytes	ts = `r_Tiling::defaultTileSize`,

	)

Class constructor.

◆ ~r_Dir_Tiling()

r_Dir_Tiling::~r_Dir_Tiling ( )

overridedefault

The user has to give the number of dimensions of the space and the decomposition wanted for that space.

Note that the number of elements of decomp must be the same as the number of dimensions of the space. See r_Dir_Decompose for details on how to indicate a decomposition. SubTiling indicates if subtiling should occur inside the blocks specified by the user. Throws an exception when the decomp.size is not equal to the specified dimension.

Member Function Documentation

◆ clone()

r_Tiling* r_Dir_Tiling::clone ( ) const

overridevirtual

This method provides the core funcionality of this class.

All derived classes must implement it. As input parameters it takes the big object to be decomposed and returns a set of tiles that compose the big object. This method throws an exeception when the dimension specified, extend or the cell_size are incompatible with the current tiling. You can check compatibility by invoking is_compatible. Clones this object

Implements r_Dimension_Tiling.

◆ compute_tiles()

std::vector<r_Minterval> r_Dir_Tiling::compute_tiles	(	const r_Minterval &	obj_domain,
		r_Bytes	cell_size
	)		const

overridevirtual

Decompose an object in tiles.

Implements r_Dimension_Tiling.

◆ get_name_from_subtiling()

static const char* r_Dir_Tiling::get_name_from_subtiling ( SubTiling st )

static

Get a tilisize limit name for a tilesize limit.

◆ get_subtiling_from_name()

static r_Dir_Tiling::SubTiling r_Dir_Tiling::get_subtiling_from_name ( const char * name )

static

Get a tilesize limit for a tilisize limit name.

◆ get_tiling_scheme()

r_Tiling_Scheme r_Dir_Tiling::get_tiling_scheme ( ) const

overridevirtual

This method is similar to a copy constructor, this is, is returns a copy of the current object.

Derived classes must explicitly implement this method.

Implements r_Tiling.

◆ is_compatible()

bool r_Dir_Tiling::is_compatible	(	const r_Minterval &	obj_domain,
		r_Bytes	cellTypeSize
	)		const

overridevirtual

Check compatibility of object domain with this tiling.

Implements r_Tiling.

◆ print_status()

void r_Dir_Tiling::print_status ( std::ostream & os ) const

overridevirtual

Prints the current status of the object.

Implements r_Tiling.

const char* r_Dir_Tiling::subtiling_name_withoutsubtiling

staticprotected

The names of all subtiling types, to avoid redundant storage and inconsistencies.

The variable name convention is the prefix subtiling_name_ followed by the name of the data format in lower case, i.e. for WITH_SUBTILING subtiling_name_withsubtiling. In addition there's an array of names all_subtiling_names where the subtiling can be used as index to get the name.
