#include </home/zeitlin/src/wx/github/interface/wx/sharedptr.h>
A smart pointer with non-intrusive reference counting.
It is modelled after boost::shared_ptr<>
and can be used with STL containers and wxVector<T> unlike std::auto_ptr<>
and wxScopedPtr<T>.
Public Member Functions | |
wxEXPLICIT | wxSharedPtr (T *ptr=NULL) |
Constructor. | |
wxSharedPtr (const wxSharedPtr< T > &tocopy) | |
Copy constructor. | |
~wxSharedPtr () | |
Destructor. | |
T * | get () const |
Returns pointer to its object or NULL. | |
operator unspecified_bool_type () const | |
Conversion to a boolean expression (in a variant which is not convertible to anything but a boolean expression). | |
T | operator* () const |
Returns a reference to the object. | |
T * | operator-> () const |
Smart pointer member access. | |
wxSharedPtr< T > & | operator= (T *ptr) |
Assignment operator. | |
wxSharedPtr< T > & | operator= (const wxSharedPtr< T > &tocopy) |
Assignment operator. | |
void | reset (T *ptr=NULL) |
Reset pointer to ptr. | |
bool | unique () const |
Returns true if this is the only pointer pointing to its object. | |
long | use_count () const |
Returns the number of pointers pointing to its object. |
wxEXPLICIT wxSharedPtr< T >::wxSharedPtr | ( | T * | ptr = NULL | ) |
Constructor.
Creates shared pointer from the raw pointer ptr and takes ownership of it.
wxSharedPtr< T >::wxSharedPtr | ( | const wxSharedPtr< T > & | tocopy | ) |
Copy constructor.
wxSharedPtr< T >::~wxSharedPtr | ( | ) |
Destructor.
T* wxSharedPtr< T >::get | ( | ) | const |
Returns pointer to its object or NULL.
wxSharedPtr< T >::operator unspecified_bool_type | ( | ) | const |
Conversion to a boolean expression (in a variant which is not convertible to anything but a boolean expression).
If this class contains a valid pointer it will return true, if it contains a NULL pointer it will return false.
T wxSharedPtr< T >::operator* | ( | ) | const |
Returns a reference to the object.
If the internal pointer is NULL this method will cause an assert in debug mode.
T* wxSharedPtr< T >::operator-> | ( | ) | const |
Smart pointer member access.
Returns pointer to its object.
If the internal pointer is NULL this method will cause an assert in debug mode.
wxSharedPtr<T>& wxSharedPtr< T >::operator= | ( | T * | ptr | ) |
Assignment operator.
Releases any previously held pointer and creates a reference to ptr.
wxSharedPtr<T>& wxSharedPtr< T >::operator= | ( | const wxSharedPtr< T > & | tocopy | ) |
Assignment operator.
Releases any previously held pointer and creates a reference to the same object as topcopy.
void wxSharedPtr< T >::reset | ( | T * | ptr = NULL | ) |
Reset pointer to ptr.
If the reference count of the previously owned pointer was 1 it will be deleted.
bool wxSharedPtr< T >::unique | ( | ) | const |
Returns true if this is the only pointer pointing to its object.
long wxSharedPtr< T >::use_count | ( | ) | const |
Returns the number of pointers pointing to its object.
