convex.core.lang.Ops

public class Ops
extends Object

Static utility class for coded operations. Ops are the fundamental units of code (e.g. as used to implement Actors), and may be effectively considered as "bytecode" for the decentralised state machine.

Method Details

read

public static <T extends ACell> AOp<T> read(Blob b,
 int pos,
 byte opCode)
                                     throws BadFormatException
