Modern SharedPtr Ref

Ref

Returns a reference to the object; raises an error if the handle is null.

Syntax

Ref( ) byref as T
Ref( )

Examples

#import "std/memory"
using memory

type Node
    as int32 id
end type

dim p as SharedPtr( of Node ) = MakeShared( of Node )( )

'' A reference to the pointee, so members read without the -> dance
p.Ref( ).id = 7
print p.Ref( ).id            '' 7

'' Ref( ) on a NULL handle has nothing to refer to -- guard with IsNull
dim empty_ as SharedPtr( of Node )
print empty_.IsNull( )       '' true
