Examples of ShpFiles

org.geotools.data.shapefile.ShpFiles
org.geotools.data.shapefile.files.ShpFiles
The collection of all the files that are the shapefile and its metadata and indices.
This class has methods for performing actions on the files. Currently mainly for obtaining read and write channels and streams. But in the future a move method may be introduced.

Note: The method that require locks (such as getInputStream()) will automatically acquire locks and the javadocs should document how to release the lock. Therefore the methods {@link #acquireRead(ShpFileType,FileReader)} and {@link #acquireWrite(ShpFileType,FileWriter)}svn
