Package de.learnlib.oracle.membership

Class AbstractSULOmegaOracle<S,I,O,Q>

java.lang.Object

de.learnlib.oracle.membership.AbstractSULOmegaOracle<S,I,O,Q>

Type Parameters:

S - the state type of the ObservableSUL

I - the input type

O - the output type

Q - the state information type that is used to answer OmegaQuerys

All Implemented Interfaces:

OmegaMembershipOracle<Q,I,Word<O>>, OmegaMembershipOracle.MealyOmegaMembershipOracle<Q,I,O>, OmegaQueryAnswerer<Q,I,Word<O>>, BatchProcessor<OmegaQuery<I,Word<O>>>

public abstract class AbstractSULOmegaOracle<S,I,O,Q>
extends Object
implements OmegaMembershipOracle.MealyOmegaMembershipOracle<Q,I,O>

An omega membership oracle for an ObservableSUL.

The behavior is similar to a SULOracle, except that this class answers OmegaQuerys.

After some symbols (i.e. after OmegaQuery.getPrefix(), and after each OmegaQuery.getLoop()) the state of the ObservableSUL is retrieved, and used to answer the query.

This class is not thread-safe.
