Constructor & Destructor Documentation

◆ r_Stat_Tiling() [1/2]

r_Stat_Tiling::r_Stat_Tiling ( const char * encoded )

explicit

read everything from an encoded string e.g.

"2;[0:9,0:9],3;[100:109,0:9],2;2;0.3;100"

◆ r_Stat_Tiling() [2/2]

r_Stat_Tiling::r_Stat_Tiling	(	r_Dimension	dim,
		const std::vector< r_Access > &	stat_info,
		r_Bytes	ts = `r_Tiling::defaultTileSize`,
		r_Area	border_threshold = `DEF_BORDER_THR`,
		r_Double	interesting_threshold = `DEF_INTERESTING_THR`
	)

Class constructor.

◆ ~r_Stat_Tiling()

virtual r_Stat_Tiling::~r_Stat_Tiling ( )

virtualdefault

This is the "Statistic Tiling" class constructor.

It takes as parameters the threshold for, when performing filtering, considering two borders the same, and also, the threshold at which an area is considered interesting and should be taken in account when performing tiling. Finally, the tilesize is considered as a parameter. stat_info inputs the statistic information into the class and calculates the new interest areas that will be used to perform tiling on the object. An exception is thrown when the statistical data does not fit the dimension.

Member Function Documentation

◆ clone()

r_Tiling * r_Stat_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_Stat_Tiling::compute_tiles	(	const r_Minterval &	obj_domain,
		r_Bytes	cell_size
	)		const

overridevirtual

Decompose an object in tiles.

Implements r_Dimension_Tiling.

◆ filter()

void r_Stat_Tiling::filter ( std::vector< r_Access > & patterns ) const

protected

Filters and access pattern table (list) throws exception if dimensions of access patterns are not the same.

◆ get_border_threshold()

r_Area r_Stat_Tiling::get_border_threshold ( ) const

Gets the threshold at which to intervals are considered the same.

◆ get_interesting_areas()

virtual const std::vector< r_Minterval > & r_Stat_Tiling::get_interesting_areas ( ) const

virtual

Gets the statistical information.

◆ get_interesting_threshold()

r_Double r_Stat_Tiling::get_interesting_threshold ( ) const

This method gets the number of points (pixels/cells) at which two intervals are considered to be the same, in the access patterns.

Gets the threshold at which an area is considered to be interesting

◆ get_tiling_scheme()

r_Tiling_Scheme r_Stat_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.

Reimplemented from r_Size_Tiling.

◆ merge()

r_Access r_Stat_Tiling::merge ( const std::vector< r_Access > & patterns ) const

protected

Merges a list of access patterns.

◆ print_status()

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

overridevirtual

This method gets the threshold at which an area is considered to be interesting.

All the areas that are accessed above the specified threshold, will be considered interest areas when performing tiling.

Reimplemented from r_Dimension_Tiling.
