Constructor Detail

DeterminedSize

public DeterminedSize(IO.Readable io,
                      int firstBuffer,
                      int secondBuffer)

Constructor.

Method Detail

skipAsync

public AsyncSupplier<Long,IOException> skipAsync(long n)

Description copied from interface: IO.Readable

Returns the number of bytes skipped.

Specified by:

skipAsync in interface IO.Readable

skip

public int skip(int skip)

Description copied from interface: IO.ReadableByteStream

Same as IO.Readable.skipSync(long) but limited to an integer.

Specified by:

skip in interface IO.ReadableByteStream

Overrides:

skip in class TwoBuffersIO

getSizeSync

public long getSizeSync()

Description copied from interface: IO.KnownSize

Synchronous operation to get the size of the IO.

Specified by:

getSizeSync in interface IO.KnownSize

Overrides:

getSizeSync in class TwoBuffersIO

getSizeAsync

public AsyncSupplier<Long,IOException> getSizeAsync()

Description copied from interface: IO.KnownSize

Asynchronous operation to get the size of the IO.

Specified by:

getSizeAsync in interface IO.KnownSize

Overrides:

getSizeAsync in class TwoBuffersIO

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 TwoBuffersIO
