TastyReader

class TastyReader(val bytes: Array[Byte], start: Int, end: Int, val base: Int)

A byte array buffer that can be filled with bytes or natural numbers in TASTY format, and that supports reading and patching addresses represented as natural numbers.

Value Params
base

The index referenced by the logical zero address Addr(0)

bytes

The array containing data

end

The position one greater than the last byte to be read

start

The position from which to read
