public void post()

Specified by:

post in interface SUL<I,O>

step

createCacheConsistencyTest

public EquivalenceOracle.MealyEquivalenceOracle<I,O> createCacheConsistencyTest()

Description copied from interface: LearningCache

Creates a cache consistency test. A cache consistency test is an equivalence oracle which checks a given hypothesis against the current contents of the cache. Hence, no queries are posed to the underlying system.

The created cache consistency test is backed by the cache contents. This method does not need to be invoked repeatedly when the cache contents change.

Specified by:

createCacheConsistencyTest in interface LearningCache<I,O,C extends de.learnlib.filter.cache.sul.AbstractSULCache.SULCacheState<I,O>>

Returns:

a cache consistency test for the contents of this cache

addAlphabetSymbol

public void addAlphabetSymbol(I symbol)

Specified by:

addAlphabetSymbol in interface net.automatalib.alphabet.SupportsGrowingAlphabet<I>

suspend

public C suspend()

Specified by:

suspend in interface Resumable<I>

resume

public void resume(C state)

Specified by:

resume in interface Resumable<I>

size

public int size()
