Detailed Description

template<typename T>
class OpenDDS::DCPS::DurabilityArray< T >

Array class that provides a means to reset the underlying ACE_Allocator.

This class only exists to provide a means to reset the allocator used by the ACE_Array_Base base class. It has a specific use case, namely to correctly support instances created by a persistent allocator. The allocator address may change between process runs, meaning the allocator address stored in the persistent ACE_Array_Base instance will be invalid. Use the set_allocator() method to reset the allocator address before performing any operations that will require use of the allocator (e.g. increasing the size of the array).
