Class TPKBundle.SequentialInputFile

  • Enclosing class:
    TPKBundle
    public class TPKBundle.SequentialInputFile
extends Object
    This object is used to manage the bundle data file and the bundle index file. We are using the InputStream object returned by ZipFile.getInputStream(ZipEntry) to read data from these files. The idea is to read in a forward direction (skipping bytes appropriately) whenever possible. If the request is for an offset that is "behind" our current position the object will close the current InputStream, get a "new" one and satisfy the read request.
