MetaStreamable interface

Overview

MetaStreamable is a meta interface to support input/output streaming operators << and >>.
A Variant that meta type implementing MetaStreamable can be used in I/O streaming operators.

Implement MetaStreamable

Usually you don't need to construct MetaStreamable directly. You should inherit the declared meta type from MetaStreamableBase.
For example, assume MyClass supports I/O streaming, then we can DeclareMetaType MyClass as below,

// the header for MetaStreamableBase
#include "metapp/interfaces/bases/metastreamablebase.h"

template <>
struct metapp::DeclareMetaType <MyClass> : metapp::MetaStreamableBase <MyClass>
{
};
