                            IFAState matchedState)

Method Detail

hasFinalState

public boolean hasFinalState()

Specified by:

hasFinalState in interface IStateMatchInfo

Returns:

whether current matched state has a final state

hasOnlyPreciseMatchTransition

public boolean hasOnlyPreciseMatchTransition()

Specified by:

hasOnlyPreciseMatchTransition in interface IStateMatchInfo

Returns:

whether the transitions, current matched states have, are only precise match transition, that only matches specified event rather than batch events

hasNoPreciseMatchTransition

public boolean hasNoPreciseMatchTransition()

Specified by:

hasNoPreciseMatchTransition in interface IStateMatchInfo

Returns:

whether none of the transitions, current matched states have, is precise match transition, that only matches specified event rather than batch events

isSingleFuzzyMatchTransition

public boolean isSingleFuzzyMatchTransition()

Specified by:

isSingleFuzzyMatchTransition in interface IStateMatchInfo

Returns:

whether current match state only have one transition, and it is a fuzzy transition that may match batch events

getOneMatchedState

public IFAState getOneMatchedState()

Specified by:

getOneMatchedState in interface IStateMatchInfo

Returns:

one of the matched state

addMatchedState

public void addMatchedState(IFAState state)

Specified by:

addMatchedState in interface IStateMatchInfo

getMatchedState

public IFAState getMatchedState(int stateOrdinal)

Specified by:

getMatchedState in interface IStateMatchInfo

Parameters:

stateOrdinal - the target state's ordinal of matched order

Returns:

the ordinal(th) matched state

getMatchedStateSize

public int getMatchedStateSize()

Specified by:

getMatchedStateSize in interface IStateMatchInfo

Returns:

size of current matched states

getSourceStateOrdinal

public int getSourceStateOrdinal()

Specified by:

getSourceStateOrdinal in interface IStateMatchInfo

Returns:

the ordinal of the source state in matched order

setSourceStateOrdinal

public void setSourceStateOrdinal(int sourceStateOrdinal)

Specified by:

setSourceStateOrdinal in interface IStateMatchInfo

Parameters:

sourceStateOrdinal - the ordinal of the source state in matched order

getSourceTransitionIterator

public java.util.Iterator<IFATransition> getSourceTransitionIterator()

Specified by:

getSourceTransitionIterator in interface IStateMatchInfo

Returns:

the iterator of current checking source states' transition

setSourceTransitionIterator

public void setSourceTransitionIterator(java.util.Iterator<IFATransition> sourceTransitionIterator)

Specified by:

setSourceTransitionIterator in interface IStateMatchInfo

Parameters:

sourceTransitionIterator - the iterator of current checking source states' transition
