/**

|
* @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.
|
||
|
