```
public interface PlcQuery
```
Base type for all query types. Typically, every driver provides an implementation of this interface in order to be able to describe the queries of a browse request. As this is completely tied to the implemented protocol, this base interface makes absolutely no assumption to any information it should provide. In order to stay platform and protocol independent every driver connection implementation provides a prepareQuery(String) method that is able to parse a string representation of a resource into it's individual query type. Manually constructing PlcQuery objects manually makes the solution less dependent on the protocol, but might be faster.
