/**

|
* @brief This is a helper class implements the Attorney-Client idiom for access to
|
|
* LocalDataPoolManager internals
|
|
* @details
|
|
* This helper class provides better control over which classes are allowed to access
|
|
* LocalDataPoolManager internals in a granular and encapsulated way when compared to
|
|
* other methods like direct friend declarations. It allows these classes to use
|
|
* an explicit subset of the pool manager private/protected functions.
|
|
* See: https://en.wikibooks.org/wiki/More_C%2B%2B_Idioms/Friendship_and_the_Attorney-Client
