Detailed Description

template<class TYPE>
class ACE_Managed_Object< TYPE >

Wrapper for interface to allocate an object managed by the ACE_Object_Manager.

This template class wraps an interface that is used to allocate and access an object that is managed by the ACE_Object_Manager. Because static template member functions are not supported by some compilers, it is a separate (template) class. This interface is typically used to replace a static object with one that is dynamically allocated. It helps to avoid problems with order of static object construction/destruction. Managed objects won't be allocated until needed, but should be allocated when first needed. And they are destroyed in the reverse order of construction. <get_preallocated_object> accesses a "preallocated" object, i.e., one that is identified by a value in the ACE_Object_Manager:: Preallocated_Object enum. These objects are used internally by the ACE library. Hooks are provided for the application to preallocate objects via the same mechanism. ACE_APPLICATION_PREALLOCATED_OBJECT_DECLARATIONS can be used to define enum values; ACE_APPLICATION_PREALLOCATED_OBJECT_DEFINITIONS can be used to define the corresponding objects. The format of the ACE internal library definitions should be followed. And similarly, ACE_APPLICATION_PREALLOCATED_ARRAY_DECLARATIONS and ACE_APPLICATION_PREALLOCATED_ARRAY_DEFINITIONS can be used to preallocate arrays. By default, preallocation uses dynamic allocation. The preallocated objects and arrays are allocated off the heap in the ACE_Object_Manager constructor. To statically place the preallocated objects in program global data instead of on the heap, define ACE_HAS_STATIC_PREALLOCATION prior to building the ACE library.
