class TastyReader

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.

[+] def startAddr : Addr

The address of the first byte to read, respectively byte that was read

[+] def subReader ( start: Addr , end: Addr ) : TastyReader

A new reader over the same array with the same address base, but with specified start and end positions

[+] def until ( end: Addr ) ( op: => T ) : List [ T ]

Perform op until end address is reached and collect results in a list.
