Constructor & Destructor Documentation

AnyPtr ( )

Default constructor builds a NULL AnyPtr.

AnyPtr ( T * ptr ) [explicit]

Constructor taking a generic (raw) pointer type.

Parameters:

	T	: (`template` parameter) Defines the input pointer type.
	ptr	: The input pointer.

AnyPtr ( shared_ptr< T > ptr ) [explicit]

Constructor taking a shared_ptr<T>.

Parameters:

	T	: (`template` parameter) Defines the input pointer type.
	ptr	: The input pointer.

operator shared_ptr< T > ( ) const

Automatic cast to shared_ptr<T>.

Parameters:

T : (template parameter) Defines the output type.

Returns:: If this pointer points to an object of type T, then this method returns this pointer cast to shared_ptr<T>. Otherwise, it returns a null shared_ptr<T>.

operator bool ( ) const

Automatic conversion to bool.

Returns:: This function returns true if the pointer is non NULL and false otherwise.

void swap ( AnyPtr & other )

Non throwing swap.

Parameters:

other

: The other AnyPtr to be swapped.

void thrower ( ) const [private]

The thrower function.
