Class ConversionsTestCoordLoader

java.lang.Object
  us.zuercher.gpx2map.coord.test.ConversionsTestCoordLoader

All Implemented Interfaces:

Iterable<ConversionsTestCoordLoader.Equivalence>

public class ConversionsTestCoordLoader
extends Object
implements Iterable<ConversionsTestCoordLoader.Equivalence>

ConversionsTestCoordLoader loads test coordinates from a file and provides an ConversionsTestCoordLoader.EquivIterator over a disk-based collection of ConversionsTestCoordLoader.Equivalence objects. The collection is never loaded into memory as it is quite large. Currently the format of this file is:

  {lat} {lon} northing: {north} easting: {east} zone: {Z} letter: {L}

Constructor Detail

ConversionsTestCoordLoader

public ConversionsTestCoordLoader(File coordsFile)

Construct a ConversionsTestCoordLoader from a given file.

Parameters:

coordsFile - file containing a list of equivalent coordinates

ConversionsTestCoordLoader

public ConversionsTestCoordLoader(URL coordsResource)

Construct a ConversionsTestCoordLoader from a given URL. Typically the URL is a resource URL, but need not be.

Parameters:

coordsResource - URL referring to a list of equivalent coordinates

Method Detail

iterator

public Iterator<ConversionsTestCoordLoader.Equivalence> iterator()

Returns an iterator over Equivalence objects that represent the entries in the coordinates file or URL used to construct this class.

Specified by:

iterator in interface Iterable<ConversionsTestCoordLoader.Equivalence>

Returns:

an Equivalence object Iterator

Throws:

IllegalStateException - if there's an error reading the file
