@Deprecated
public class Logic
extends java.lang.Object
Deprecated.
this class is deprecated for relying on metadata (`langspec.json`) that
does not accurately represent opcode behavior across program versions.
Logic class provides static checkProgram function
that can be used for client-side program validation for size and execution cost.

putUVarint
public static byte[] putUVarint(int value)Deprecated.Varints are a method of serializing integers using one or more bytes. Smaller numbers take a smaller number of bytes. Each byte in a varint, except the last byte, has the most significant bit (msb) set – this indicates that there are further bytes to come. The lower 7 bits of each byte are used to store the two's complement representation of the number in groups of 7 bits, the least significant group first. https://developers.google.com/protocol-buffers/docs/encoding- Parameters:
value
- being serialized- Returns:
- byte array holding the serialized bits
-
getUVarint
Deprecated.Given a varint, get the integer value- Parameters:
buffer
- serialized varintbufferOffset
- position in the buffer to start reading from- Returns:
- pair of values in an array: value, read size
