/**
* @brief The DataSetBase class manages a set of locally checked out variables.
* @details
* This class manages a list, where a set of local variables (or pool variables)
* are registered. They are checked-out (i.e. their values are looked
* up and copied) with the read call. After the user finishes working with the
* pool variables, he can write back all variable values to the pool with
* the commit call. The data set manages locking and freeing the data pool,
* to ensure that all values are read and written back at once.
*
* An internal state manages usage of this class. Variables may only be
* registered before the read call is made, and the commit call only
* after the read call.
*
* If pool variables are writable and not committed until destruction
* of the set, the DataSet class automatically sets the valid flag in the
* data pool to invalid (without) changing the variable's value.
*
* The base class lockDataPool und unlockDataPool implementation are empty
* and should be implemented to protect the underlying pool type.
