Class DbInputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable
    public class DbInputStream
extends AutoCloseInputStream
    This class represents an input stream backed by a database. The database objects are only acquired when reading from the stream, and stay open until the stream is closed, fully read, or garbage collected.

    This class does not support mark/reset. It is always to be wrapped using a BufferedInputStream.
