Class TiledRoverStore

java.lang.Object
  com.partnersoft.v3x.apps.MapBrowser.rover.TiledRoverStore

All Implemented Interfaces:

java.io.Serializable

public class TiledRoverStore
extends java.lang.Object
implements java.io.Serializable

A TiledRoverStore is responsible for locating and returning Rover files based on their SheetCoord. Implementations can perform this in a variety of ways and pull their data from a variety of sources. It also encapsulates the knowledge of the database's extents - for any given SheetCoord, it knows whether a rover file exists.

Method Detail

getRoverStream

public java.io.InputStream getRoverStream(long coord)
                                   throws java.io.IOException

Returns a Rover input stream associated with a SheetCoord. You can assume the stream is buffered in some fashion (via BufferedInputStream or by being already in memory).

Throws:

java.io.IOException

createPointDumpFor

public PackedObjectDump createPointDumpFor(long tile)

Creates a point dump for the given tile.

createLineDumpFor

public PackedGoedelObjectDump createLineDumpFor(long tile)

Creates a line dump for the given tile.

tileExists

public boolean tileExists(SheetCoord coords)

tileExists

public boolean tileExists(long coords)

sheetContaining

public SheetCoord sheetContaining(Coord3D coord,
                                  int scaleIndex)

Return the SheetCoord for the given ground coordinate at the given scale; set the content yourself if you need to.

packedSheetContaining

public long packedSheetContaining(Coord3D coord,
                                  int scaleIndex)

Return the PackedSheetCoord for the given ground coordinate at the given scale.

roverTilingAt

public RoverTiling roverTilingAt(int index)

Return the RoverTiling for the given index.
