Class SQOOTBridge<I,O>

java.lang.Object

de.learnlib.algorithms.adt.util.SQOOTBridge<I,O>

Type Parameters:

I - input alphabet type

O - output alphabet type

All Implemented Interfaces:

MembershipOracle<I,net.automatalib.words.Word<O>>, QueryAnswerer<I,net.automatalib.words.Word<O>>, SymbolQueryOracle<I,O>

@ParametersAreNonnullByDefault
public class SQOOTBridge<I,O>
extends Object
implements SymbolQueryOracle<I,O>

A utility class that links an observation tree with a symbol query oracle, meaning that all queries to the symbol query oracle will be stored in the observation tree. Additionally, if a query can be answered by the observation tree (and caching is enabled) the delegated symbol query oracle will not be queried.
