LzopOutputStream

public LzopOutputStream(OutputStream out,
                        LzoCompressor compressor,
                        @CheckForSigned
                        int inputBufferSize,
                        long flags)
                 throws IOException

Constructs a new LzopOutputStream.

I recommend limiting flags to the following unless you REALLY know what you are doing:

• LzopConstants.F_ADLER32_C
• LzopConstants.F_ADLER32_D
• LzopConstants.F_CRC32_C
• LzopConstants.F_CRC32_D

Throws:

IOException
