Detailed Description

template<typename T>
class ucommon::temporary< T >

Manage temporary object stored on the heap.

This is used to create a object on the heap who's scope is controlled by the scope of a member function call. Sometimes we have data types and structures which cannot themselves appear as auto variables. We may also have a limited stack frame size in a thread context, and yet have a dynamic object that we only want to exist during the life of the method call. Using temporary allows any type to be created from the heap but have a lifespan of a method's stack frame.

Member Function Documentation

template<typename T >

T& ucommon::temporary< T >::operator*

(

)

[inline]

Access heap object through our temporary directly.

Returns:

reference to heap resident object.

Definition at line 311 of file generics.h.

template<typename T >

T* ucommon::temporary< T >::operator->

(

)

[inline]

Access members of our heap object through our temporary.

Returns:

member reference of heap object.

Definition at line 318 of file generics.h.

template<typename T >

T& ucommon::temporary< T >::operator=

(

T *

temp

)

[inline]

Assign a temporary object.

This adds a pointer to an existing type to the current temporary pointer. If the temporary was already assigned, then it is deleted.

Parameters:

temp	object to assign.

Definition at line 288 of file generics.h.

template<typename T >

void ucommon::temporary< T >::set

(

T *

temp

)

[inline]

Assign a temporary object.

This adds a pointer to an existing type to the current temporary pointer. If the temporary was already assigned, then it is deleted.

Parameters:

temp	object to assign.
