This function will take a reference obtained by the ref function and returns its Lua element.
Syntax
mixed deref( int reference )
Required Arguments
- reference: The valid reference, which you want to dereference
Returns
Returns mixed if the reference were valid. Returns false if the reference were invalid.
Remarks
This function was originally created to prevent garbage-collection of specific Lua objects/elements which should persist even though no script would reference them. The storage of those references can be obtained by a call to the debug.getregistry function. The ref and deref template can easily be remade using a locally-hidden Lua table and two such function implementations.
