SPVM::Runtime - Runtime

Description

SPVM::Runtime is the Runtime class in the SPVM language.

The instance has the runtime information such as operation codes, classes, methods, fields, class variables, constant strings.

This class provides only the minimal methods to get the information of classes and methods.

An instance of the Runtime class is build by the build_runtime method in the Compiler class.

A execution environemt is build by the build_env method in this class.

Usage

use Runtime;

my $runtime = $compiler->build_runtime;

my $class_names = $runtime->get_class_names;

my $method_names = $runtime->get_method_names("Foo");

my $env = $runtime->build_env;

my $stack = $env->build_stack;

Pointer

The Runtime class is a pointer class.

Its insntace has a pointer to a runtime object.
