Value

This class represents different parts of an instruction.

While an easy way to understand what instruction is is to imagine that it is everything that ends with ";" e.g

require(predicate); 
uint a = 0;
foo(bar()-1);

These are all examples of instructions.

Value represents the internal parts of instruction, e.g for the instruction:

foo(bar()-1);

the bar() - call, bar()-1 expression and foo(bar()-1) calls will be the values of the instruction.

While the Value is a very important part of the engine, one will most likely never work with the Value class directly, but rather with the derived classes of the Value, which are:

• Call

• Var

• ValueExpression

• ValueContractType

• Literal
