Class InputStreamFromRandomAccessFile

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable
    public class InputStreamFromRandomAccessFile
extends java.io.InputStream
    Provides an InputStream view into the current position in a RandomAccessFile.

    Useful for performing buffered reading from a RandomAccessFile which otherwise isn't possible without using Java 7. So instead of reading directly from a RandomAccessFile once you have set a position, instead construct : new DataInputStream(new BufferedInputStream(new InputStreamFromRandomAccessFile(randomAccessFile),64)) to read from instead. Note that closing the stream created does not forward the close on to the random access file.

    Since:
    API 4.40 (Geneious 5.4.0)
