Detailed Description

template<typename T>
class wxScopedPtr< T >

A scoped pointer template class.

It is the template version of the old-style scoped pointer macros.

Notice that objects of this class intentionally cannot be copied.

Library:  wxBase

Constructor & Destructor Documentation

template<typename T >

wxScopedPtr< T >::wxScopedPtr

(

T *

ptr = NULL

)

Constructor takes ownership of the pointer.

Parameters:

ptr	Pointer allocated with new or NULL.

template<typename T >

wxScopedPtr< T >::~wxScopedPtr

(

)

Destructor deletes the pointer.

Member Function Documentation

template<typename T >

T* wxScopedPtr< T >::get

(

)

const

Returns pointer to object or NULL.

template<typename T >

wxScopedPtr< 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.

template<typename T >

T& wxScopedPtr< T >::operator*

(

)

const

Returns a reference to the object.

If the internal pointer is NULL this method will cause an assert in debug mode.

template<typename T >

T* wxScopedPtr< T >::operator->

(

)

const

Smart pointer member access.

Returns pointer to object.

If the internal pointer is NULL this method will cause an assert in debug mode.

template<typename T >

T* wxScopedPtr< T >::release

(

)

Releases the current pointer and returns it.

注意:

Afterwards the caller is responsible for deleting the data contained in the scoped pointer before.

template<typename T >

void wxScopedPtr< T >::reset

(

T *

ptr = NULL

)

Reset pointer to the value of ptr.

The previous pointer will be deleted.

template<typename T >

void wxScopedPtr< T >::swap

(

wxScopedPtr< T > &

ot

)

Swaps pointers.
