Interface ISQuery<RESULT>

Type Parameters:

RESULT - the type of the expected results.

All Known Subinterfaces:

All Known Implementing Classes:

AbstractQuery

public interface ISQuery<RESULT>

Defines the minimal behaviour of queries accepted by ISClients: they contain their textual expression and specify a time-to-live for their results.

The definition is parametric with respect to the type of the expected results. This is not required for the interface, though it may be for its implementations. In addition, it allows static typing of the ISClient interface.
