Detailed Description

template<typename T>
class openPMD::DynamicMemoryView< T >

A view into a buffer that might be reallocated at some points and thus has changing base pointers over time.

Reasoning: ADIOS2's span-based Engine::Put() API returns spans whose base pointers might change after internal reallocations. Hence, the concrete pointer needs to be acquired right before writing to it. Otherwise, a use after free might occur.
