Method Detail

### seek

    public abstract void seek(long localPos)
                       throws java.io.IOException

  Parameters:
    `localPos` -
  Throws:
    `java.io.IOException`

### getOffset

    public abstract long getOffset()
                            throws java.io.IOException

  Throws:
    `java.io.IOException`

### length

    public abstract long length()
                         throws java.io.IOException

  Throws:
    `java.io.IOException`

### readInt

    public abstract int readInt()
                         throws java.io.IOException

  Returns:
  Throws:
    `java.io.IOException`

### readLong

    public abstract long readLong()
                           throws java.io.IOException

  Throws:
    `java.io.IOException`

### readFully

    public abstract void readFully(byte[] b,
                                   int off,
                                   int len)
                            throws java.io.IOException

  Throws:
    `java.io.IOException`

### refresh

    public abstract void refresh()
                          throws java.io.IOException

  Throws:
    `java.io.IOException`

### available

    public abstract int available()
                           throws java.io.IOException

  Returns the number of bytes that can be read (or skipped over) from this random access input stream without blocking by the next caller of a method for this input stream. The next caller might be the same thread or another thread.

  This abstract class is extended by `RAFolderInputStream` and `RAFileInputStream`

  The `available` method returns `-1` when no more data because the end of the stream has been reached.

  and returns `Integer.MAX_VALUE` when bytes of data is larger then Integer.MAX_VALUE.

  Overrides:
    `available` in class `java.io.InputStream`
  Throws:
    `java.io.IOException`
