Detailed Description

template<typename ptrT>
class madness::ScopedArray< ptrT >

Scoped array.

Holds a pointer to an array until it goes out of scope, then automatically deletes it. A scoped array pointer should be used to wrap pointers where the lifetime of the array pointer should be limited to a specific scope. The pointer cannot be copied. The pointer will be deleted with the delete operator.

Template Parameters

ptrT	The pointer type

Note

A pointer to type ptrT must be a complete type

This class is based on Boost scoped_array.

Member Typedef Documentation

template<typename ptrT>

typedef ptrT madness::ScopedArray< ptrT >::element_type

the pointer type

Constructor & Destructor Documentation

template<typename ptrT>

madness::ScopedArray< ptrT >::ScopedArray ( ptrT *  p = NULL )

inlineexplicit

Construct a scoped pointer.

Parameters

p	The pointer to hold [default = NULL]

Exceptions

nothing

template<typename ptrT>

madness::ScopedArray< ptrT >::~ScopedArray ( )

inline

Destructor.

Calls delete[] operator

Member Function Documentation

template<typename ptrT>

ptrT* madness::ScopedArray< ptrT >::get ( ) const

inline

Pointer accessor.

Returns

The pointer

Exceptions

nothing

template<typename ptrT>

madness::ScopedArray< ptrT >::operator bool ( ) const

inline

bool conversion operator

Returns

pointer != NULL

Exceptions

nothing

template<typename ptrT>

bool madness::ScopedArray< ptrT >::operator! ( ) const

inline

Not operator.

Returns

pointer == NULL

Exceptions

nothing

template<typename ptrT>

ptrT& madness::ScopedArray< ptrT >::operator[] ( std::size_t  i ) const

inline

Array element accessor.

Returns

The pointer

Exceptions

madness::MadnessException

If the pointer is NULL

template<typename ptrT>

void madness::ScopedArray< ptrT >::reset ( ptrT *  p = NULL )

inline

Reset the current pointer.

This will destroy the current pointer. If an new pointer is provided this pointer will be set to that value.

Parameters

p	The array pointer that will replace this pointer after deletion

Exceptions

madness::MadnessException

If p is the same as this pointer, except when this pointer is NULL.

template<typename ptrT>

void madness::ScopedArray< ptrT >::swap ( ScopedArray< ptrT > &  other )

inline

Swap the pointers.

Parameters

other

The pointer to swap with this pointer

Exceptions

nothing
