Class FlatXFileSystemStrategy

java.lang.Object

org.gvsig.raster.cache.tile.impl.disk.DefaultFileSystemStrategy

org.gvsig.raster.cache.tile.impl.disk.FlatXFileSystemStrategy

All Implemented Interfaces:

ITileFileSystemStrategy

public class FlatXFileSystemStrategy
extends DefaultFileSystemStrategy

This IFileSystemStrategy creates a directory for each zoom level of a layer. Inside the directory of a zoom level, creates a directory for each X row and inside the directory of an X row stores a file with the Y row, so OSM/0/0/0.tile represents the tile http://osm/0/0/0.png This strategy is the most spread for mobile map viewers (although is not the most efficient)

Description copied from interface: ITileFileSystemStrategy

The relative path of the tile on disk

Parameters:

row - Row of the tile

col - Column of the tile

zoomLevel - The zoom level

var - Variable which is represented in this cache structure. This is useful for netcdf and other multidimensional formats

z - Level of deep in the raster layer. This is useful for multidimensional formats

time - A format which supports 4D needs to store different time moments y different directories

Returns:

The path to append to the absolute path of the layer on disk
