C# Class HdrHistogram.ZigZagEncoding

Exposes methods to write values to a ByteBuffer with ZigZag LEB128-64b9B-variant encoding. (Little Endian Base128 Encoding, 64bit value store as a maximum of 9Bytes)

This class provides encoding and decoding methods for writing and reading ZigZag-encoded LEB128-64b9B-variant(Little Endian Base 128) values to/from a ByteBuffer. LEB128's variable length encoding provides for using a smaller number of bytes for smaller values, and the use of ZigZag encoding allows small(closer to zero) negative values to use fewer bytes. Details on both LEB128 and ZigZag can be readily found elsewhere.

The LEB128-64b9B-variant encoding used here diverges from the "original" LEB128 as it extends to 64 bit values. In the original LEB128, a 64 bit value can take up to 10 bytes in the stream, where this variant's encoding of a 64 bit values will max out at 9 bytes. As such, this encoder/decoder should NOT be used for encoding or decoding "standard" LEB128 formats (e.g.Google Protocol Buffers).
