org.geotools.data.shapefile.files.ShpFiles.acquireRead()
Acquire a URL for read only purposes. It is recommended that get*Stream or get*Channel methods are used when reading or writing to the file is desired. @see #getInputStream(ShpFileType,FileReader) @see #getReadChannel(ShpFileType,FileReader) @see #getWriteChannel(ShpFileType,FileReader) @param type the type of the file desired. @param requestor the object that is requesting the URL. The same object must release the lockand is also used for debugging. @return the URL to the file of the type requested
