public class ComplexOutput<K,V,T> extends CommandOutput<K,V,T>
CommandOutput that is used in combination with a given ComplexDataParser to produce
a domain object from the data extracted from the server. Since there already are implementations of the CommandOutput
interface for most simple types, this implementation is better suited to parse complex, often nested, data structures, for
example a map containing other maps, arrays or sets as values for one or more of its keys.
The implementation of the ComplexDataParser is responsible for mapping the data from the result to meaningful
properties that the user of the LEttuce driver could then use in a statically typed manner.
