tritechgemini.fileio.GLFFastInputStream

All Implemented Interfaces:

Closeable, Serializable, AutoCloseable

public class GLFFastInputStream
extends InputStream
implements Serializable

Fast reading of uncompressed GLF files. GLF files are a zip archive of sonar data with the main .dat data file and one or two configuration files. so far as I can tell, only the .dat file is important. This class makes it possible to read the dat file from the GLF file without actually unzipping the archive.
