Pulls bytes from the provided IndexInput.

getPosition

getReverseReader

ramBytesUsed

Reverse from srcPos, inclusive, to destPos, inclusive.

reverse

skipBytes

Absolute write byte; you must ensure dest is < max position written so far.

writeByte

writeBytes

Writes all of our bytes to the target DataOutput.

writeTo

writeVLong

getBlockBits

getForwardReader

Pos must be less than the max position written so far! Ie, you cannot "grow" the
file with this!
