Interface ConfigStorage

All Known Implementing Classes:

FileConfigStorage, NullConfigStorage

Config storage implementations are used to store a set of properties to a certain key.

A valid configuration path does not contain dots, semicolons or colons.

A valid path obeys to the same rules as java identifiers ..
