Class HeaderBlock

  • public class HeaderBlock
extends java.lang.Object
    The Header Block contains information and content about a single entry (be it a file or disk image).

    Note that we need to support multiple versions of the NuFX archive format. Some details may be invalid, depending on version, and those are documented in the getter methods.

    • Constructor Detail

      • HeaderBlock

        public HeaderBlock​(LittleEndianByteInputStream bs)
            throws java.io.IOException
        Create the Header Block. This is done dynamically since the Header Block size varies significantly.
        Throws:
        java.io.IOException

      • readThreads

        public void readThreads​(LittleEndianByteInputStream bs)
                 throws java.io.IOException
        Read in all data threads. All ThreadRecords are read and then each thread's data is read (per NuFX spec).
        Throws:
        java.io.IOException

      • getFilename

        public java.lang.String getFilename()
        Locate the filename and return it. It may have been given in the old location, in which case, it is in the String filename. Otherwise it will be in the filename thread. If it is in the thread, we shove it in the filename variable just so we don't need to search for it later. This should not be a problem, because if we write the file, we'll write the more current version anyway.

      • getFinalFilename

        public java.lang.String getFinalFilename()
        Final element in the path, in those cases where a filename actually holds a path name

      • getDataForkThreadRecord

        public ThreadRecord getDataForkThreadRecord()
        Get the data fork. Note that this first searches the data fork and then searches for a disk image; this may not be correct behavior.

      • getResourceForkThreadRecord

        public ThreadRecord getResourceForkThreadRecord()
        Get the resource fork.

      • findThreadRecord

        protected ThreadRecord findThreadRecord​(ThreadKind tk)
        Locate a ThreadRecord by it's ThreadKind.

      • getFileSystemSeparator

        public java.lang.String getFileSystemSeparator()
        Helper method to determine the file system separator. Due to some oddities, breaking apart by byte value...
