详细描述

template<typename T, typename D = DefaultDeleter<T>>
class vrpn::OwningPtr< T, D >

A unique-ownership smart pointer, with the ability to transfer ownership, but only explicitly (aka, not like auto_ptr did it).

Essentially, a hybrid of boost::scoped_ptr and std::unique_ptr that doesn't require C++11.

Limitations relative to unique_ptr: no move semantics (naturally, since no C++11, and have not implemented rvalue-reference-emulation), no stateful deleters, and no casting or conversions.

构造及析构函数说明

OwningPtr() [1/2]

template<typename T , typename D = DefaultDeleter<T>>

OwningPtr ( )

inline

Construct empty.

OwningPtr() [2/2]

template<typename T , typename D = DefaultDeleter<T>>

OwningPtr ( pointer p )

inlineexplicit

Construct with a raw pointer for a new object to take exclusive ownership of.

~OwningPtr()

template<typename T , typename D = DefaultDeleter<T>>

~OwningPtr ( )

inline

Destructor: deletes owned object, if any.

成员函数说明

get()

template<typename T , typename D = DefaultDeleter<T>>

pointer get ( ) const

inline

Gets pointer value

operator!()

template<typename T , typename D = DefaultDeleter<T>>

bool operator! ( ) const

inline

Redundant way of checking pointer validity

函数调用图:

operator*()

template<typename T , typename D = DefaultDeleter<T>>

reference_type operator* ( ) const

inline

Smart pointer operator

函数调用图:

operator->()

template<typename T , typename D = DefaultDeleter<T>>

pointer operator-> ( ) const

inline

Smart pointer operator overload

函数调用图:

release()

template<typename T , typename D = DefaultDeleter<T>>

pointer release ( )

inline

Returns the held pointer without performing the delete action.

reset()

template<typename T , typename D = DefaultDeleter<T>>

void reset ( pointer p = pointer() )

inline

Deletes the owned object, if any, and takes ownership of a new object, if one is passed.

这是这个函数的调用关系图:

swap()

template<typename T , typename D = DefaultDeleter<T>>

void swap ( type & other )

inline

Swap pointers with another OwningPtr of the same type.

valid()

template<typename T , typename D = DefaultDeleter<T>>

bool valid ( ) const

inline

Checks pointer validity
