Constructor Detail

SegmentReader

public SegmentReader(ReadableByteChannel channel,
                     int fetchSize)
              throws IOException

Throws:

IOException

Method Detail

getBufferIncrement

public int getBufferIncrement()

setBufferIncrement

public void setBufferIncrement(int bufferIncrement)

readToNextMarkerPartial

public final SegmentReader.State readToNextMarkerPartial(ByteBuffer out)
                                                  throws IOException

Reads one full segment till the next marker. Will read as much data as the provided buffer fits, if the provided buffer doesn't fit all data will return MORE_DATA.

Parameters:

out -

Returns:

Throws:

IOException

readToNextMarkerNewBuffer

public ByteBuffer readToNextMarkerNewBuffer()
                                     throws IOException

Reads one full segment till the next marker. Will allocate the necessary buffer to hold the full segment. Internally uses a growing collection of smaller buffers since the segment size is intitially unkwnown.

Returns:

Throws:

IOException

readToNextMarkerBuffers

public void readToNextMarkerBuffers(List<ByteBuffer> buffers)
                             throws IOException

Throws:

IOException

readToNextMarker

public final boolean readToNextMarker(ByteBuffer out)
                               throws IOException

Throws:

IOException

skipToMarker

public final boolean skipToMarker()
                           throws IOException

Throws:

IOException

read

public final boolean read(ByteBuffer out,
                          int length)
                   throws IOException

Throws:

IOException

curPos

public final long curPos()
