Detailed Description

Base class for nodes of a data storage tree.

This class as well as its descendants is meant for internal usage only as part of the implementation of the input interface.

The leave nodes of the data storage tree can be of types StorageBool, StorageInt, StorageDouble, and StorageNull. The branching nodes of the tree are of type StorageArray. The data storage tree serves to store data with structure described by Input::Type classes. Therefore it provides no way to ask for the type of stored data and an exception ExcStorageTypeMismatch is thrown if you use getter that do not match actual type of the node. Moreover, the tree can be only created using bottom-up approach and than can not be modified ( this can change if we want to use same storage for buffered reading of large data). However, we provide a method for deep copy of any subtree.
