VirtualMachine Class Reference

#include <virtualmachine.hpp>

Class Description

This class implements a very simple stack machine that understands just four commands (!) plus a fifth to execute sub-programs.

This class is part of module ALib Expressions. It is not too well documented as it resides in a detail namespace and is not to be used from the outside expression API.

Definition at line 37 of file virtualmachine.hpp.

◆ Decompile()

AST * Decompile ( Program &  program,
MonoAllocator &  allocator 
)
static

Static method that decompiles a program into an abstract syntax tree. Used to generate optimized, normalized, parsable expression strings.

Parameters
programThe program to decompile.
allocatorAllocator for AST objects (and their data).
Returns
The abstract syntax tree as a result of decompilation.

Parameters
programThe program to run.
scopeThe scope to use.
Returns
The result value of the expression program.
