Constructor.

Method Detail

nextIOSync

protected void nextIOSync()
                   throws IOException

Overrides:

nextIOSync in class LinkedIO.Readable

Throws:

IOException

nextIOAsync

protected void nextIOAsync(Runnable ondone,
                           IAsync<IOException> onerror,
                           Consumer rp)

Overrides:

nextIOAsync in class LinkedIO.Readable

previousIOSync

protected void previousIOSync()
                       throws IOException

Overrides:

previousIOSync in class LinkedIO.Readable

Throws:

IOException

previousIOAsync

protected void previousIOAsync(Runnable ondone,
                               IAsync<IOException> onerror,
                               Consumer rp)

Overrides:

previousIOAsync in class LinkedIO.Readable

getPosition

public long getPosition()

Description copied from interface: IO.PositionKnown

Return the current position.

Specified by:

getPosition in interface IO.PositionKnown

Overrides:

getPosition in class LinkedIO

seekSync

public long seekSync(IO.Seekable.SeekType type,
                     long move)
              throws IOException

Description copied from interface: IO.Seekable

Returns the new position. The implementation must not allow to seek after the end of the file, the method setSize should be used instead. It must accept seeking beyond the end, but position at the end, and accept seeking before the beginning, but position at the beginning.

Specified by:

seekSync in interface IO.Seekable

Overrides:

seekSync in class LinkedIO

Throws:

IOException

seekAsync

public AsyncSupplier<Long,IOException> seekAsync(IO.Seekable.SeekType type,
                                                 long move,
                                                 Consumer<Pair<Long,IOException>> ondone)

Description copied from interface: IO.Seekable

Returns the new position. The implementation must not allow to seek after the end of the file, the method setSize should be used instead. It must accept seeking beyond the end, but position at the end, and accept seeking before the beginning, but position at the beginning.

Specified by:

seekAsync in interface IO.Seekable

Overrides:

seekAsync in class LinkedIO

readSync

public int readSync(long pos,

             throws IOException

Description copied from interface: IO.Readable.Seekable

Same as IO.Readable.readSync(ByteBuffer) but read at the given position. The current position is changed to the given position plus the number of bytes read.

Specified by:

readSync in interface IO.Readable.Seekable

Overrides:

readSync in class LinkedIO

Throws:

IOException

readAsync

public AsyncSupplier<Integer,IOException> readAsync(long pos,

Description copied from interface: IO.Readable.Seekable

Same as IO.Readable.readAsync(ByteBuffer, Consumer) but read at the given position. The current position is changed to the given position plus the number of bytes read upon completion.

Specified by:

readAsync in interface IO.Readable.Seekable

Overrides:

readAsync in class LinkedIO

readFullySync

public int readFullySync(long pos,
                         ByteBuffer buffer)
