Public Member Functions
unsafe	Const_Box (T value)
	Allocate a new value.
unsafe	Const_Box (T *ptr)
	Store a non-owning pointer.
virtual void	Dispose ()
Public Member Functions inherited from MR.Misc.KeepAliveHolder< Const_Box< T > >
void	_KeepAlive (object obj, string key="")
	Keeps obj alive as long as this object exists. If key is specified, it's an optional tag for this object.
void	_DiscardKeepAlive (string key="")
	Discards the objects kept alive by this object. If key is not empty, only discards the objects with the same key. Otherwise discards all of them. This intentionally doesn't discard _KeepAliveEnclosingObject.

Static Public Member Functions
static implicit	operator Const_Box< T > (T value)
	Implicitly convert from a value, allocating a copy of it. Only Const_Box<T> has this, Box<T> intentionally doesn't.

Detailed Description

Stores a single heap-allocated value with a stable address, or a user-provided non-owning pointer. This is used for class fields of pointer types to const non-classes. Usage:

• To read a property of type Const_Box<T>?, first check is not null. If it's not null, use .Value to read the value.
• To modify the property, either assign a value of type T, or assign null. Assigning a value will allocate its copy and make the underlying pointer point to it.
