Constructor & Destructor Documentation

◆ XPtr() [1/4]

template<typename T, template< class > class StoragePolicy = PreserveStorage, void Finalizer = standard_delete_finalizer<T>, bool finalizeOnExit = false>

Rcpp::XPtr< T, StoragePolicy, Finalizer, finalizeOnExit >::XPtr ( SEXP x )

inlineexplicit

constructs a XPtr wrapping the external pointer (EXTPTRSXP SEXP)

Parameters

xp	external pointer to wrap

Definition at line 78 of file XPtr.h.

◆ XPtr() [2/4]

template<typename T, template< class > class StoragePolicy = PreserveStorage, void Finalizer = standard_delete_finalizer<T>, bool finalizeOnExit = false>

Rcpp::XPtr< T, StoragePolicy, Finalizer, finalizeOnExit >::XPtr	(	SEXP	x,
		SEXP	tag,
		SEXP	prot )

inlineexplicit

constructs a XPtr wrapping the external pointer (EXTPTRSXP SEXP)

Parameters

xp	external pointer to wrap
tag	tag to assign to external pointer
prot	protected data to assign to external pointer

Definition at line 87 of file XPtr.h.

◆ XPtr() [3/4]

template<typename T, template< class > class StoragePolicy = PreserveStorage, void Finalizer = standard_delete_finalizer<T>, bool finalizeOnExit = false>

Rcpp::XPtr< T, StoragePolicy, Finalizer, finalizeOnExit >::XPtr	(	T *	p,
		bool	set_delete_finalizer = true,
		SEXP	tag = R_NilValue,
		SEXP	prot = R_NilValue )

inlineexplicit

creates a new external pointer wrapping the dumb pointer p.

Parameters

p	dumb pointer to some object
set_delete_finalizer	if set to true, a finalizer will be registered for the external pointer. The finalizer is called when the xp is garbage collected. The finalizer is merely a call to the delete operator or the pointer so you need to make sure the pointer can be "delete" d this way (has to be a C++ object)

Definition at line 104 of file XPtr.h.

◆ XPtr() [4/4]

template<typename T, template< class > class StoragePolicy = PreserveStorage, void Finalizer = standard_delete_finalizer<T>, bool finalizeOnExit = false>

Rcpp::XPtr< T, StoragePolicy, Finalizer, finalizeOnExit >::XPtr ( const XPtr< T, StoragePolicy, Finalizer, finalizeOnExit > & other )

T & Rcpp::XPtr< T, StoragePolicy, Finalizer, finalizeOnExit >::operator* ( ) const

inline

Returns a reference to the object wrapped. This allows this object to look and feel like a dumb pointer to T

template<typename T, template< class > class StoragePolicy = PreserveStorage, void Finalizer = standard_delete_finalizer<T>, bool finalizeOnExit = false>

void Rcpp::XPtr< T, StoragePolicy, Finalizer, finalizeOnExit >::release ( )

inline

Release the external pointer (if any) immediately. This will cause the pointer to be deleted and it's storage to be set to NULL. After this call the get() method returns NULL and the checked_get() method throws an exception.

See the discussion here for the basic logic behind release: https://stat.ethz.ch/pipermail/r-help/2007-August/137871.html
