What exactly Deflater.HUFFMAN_ONLY does?

Question

Hi All,
I have this code which uses Java own library for Huffman encoding - ie Deflater.HUFFMAN_ONLY.
It compresses my input bytes very nicely. I have few questios with java strategy here ..
1 - Does the compression really only using Huffman? Or has it got something else in the background?
2 - Is there a way of getting at the huffman code table that Java creates in the background?This is to verify for me that yes I can use this class.
I have to implement a Huffman compression algorithm but if this does what I need, there is no point in me re-inveting the wheel. Afterall, I am unlikely to write as good a class as Java.
Thanks

I have to implement a Huffman compression algorithmIf you have to implement it, then you can't use this.
but if this does what I need, there is no point in me re-inveting the wheel. Afterall, I am unlikely to write as good a class as Java. Agreed.
