Detailed Description

template<class T>
class mongo::OwnedPointerVector< T >

An std::vector wrapper that deletes pointers within a vector on destruction.

The objects referenced by the vector's pointers are 'owned' by an object of this class. NOTE that an OwnedPointerVector<T> wraps an std::vector<T*>.

Constructor & Destructor Documentation

OwnedPointerVector()

template<class T >

mongo::OwnedPointerVector< T >::OwnedPointerVector ( std::vector< T * >  other )

inline

Takes ownership of all pointers contained in 'other'.

NOTE: argument is intentionally taken by value.

Member Function Documentation

operator=()

template<class T >

OwnedPointerVector & mongo::OwnedPointerVector< T >::operator= ( std::vector< T * >  other )

inline

Takes ownership of all pointers contained in 'other'.

NOTE: argument is intentionally taken by value.

release()

template<class T >

std::vector< T * > mongo::OwnedPointerVector< T >::release ( )

inline

Releases the entire vector to allow you to transfer ownership.

Leaves the OwnedPointerVector empty. Named after the similar method and pattern in std::auto_ptr.

releaseAt()

template<class T >

T * mongo::OwnedPointerVector< T >::releaseAt ( size_t  i )

inline

Releases ownership of a single element.

Sets that element to NULL and does not change size().
