Class Bufs

Method Details

• createBuf

  public static Buf createBuf(ByteBuffer byteBuffer, boolean isBit64, boolean isBigendian)

  Creates a buf based on a single NIO buffer.

  Parameters:

  byteBuffer - NIO buffer containing data

  isBit64 - 64bit-ness of buf

  isBigendian - true for big-endian data, false for little-endian

• createBuf

  public static Buf createBuf(ByteBuffer[] byteBuffers, boolean isBit64, boolean isBigendian)

  Creates a buf based on a sequence of NIO buffers.

  Parameters:

  byteBuffers - array of NIO buffers containing data

  isBit64 - 64bit-ness of buf

  isBigendian - true for big-endian data, false for little-endian

• createBuf

  public static Buf createBuf(File file, boolean isBit64, boolean isBigendian) throws IOException

  Creates a buf based on a file.

  Parameters:

  file - file containing data

  isBit64 - 64bit-ness of buf

  isBigendian - true for big-endian data, false for little-endian

  Throws:

  IOException

• uncompress

  public static Buf uncompress(Compression compression, Buf inBuf, long inOffset, long outSize) throws IOException

  Decompresses part of an input Buf into an output Buf.

  Parameters:

  compression - compression format

  inBuf - buffer containing input compressed data

  inOffset - offset into inBuf at which the compressed data starts

  outSize - byte count of the uncompressed data

  Returns:

  new buffer of size outSize containing uncompressed data

  Throws:

  IOException

• createByteBufferInputStream

  public static InputStream createByteBufferInputStream(ByteBuffer bbuf)

  Utility method to acquire the data from an NIO buffer in the form of an InputStream.

  Parameters:

  bbuf - NIO buffer

  Returns:

  stream
