Pattern<T,F>	Pattern.optional()	Specifies that this pattern is optional for a final match of the pattern sequence to happen.
Pattern<T,F>	GroupPattern.or(IterativeCondition<F> condition)
Pattern<T,F>	Pattern.or(IterativeCondition<F> condition)	Adds a condition that has to be satisfied by an event in order to be considered a match.

<S extends F> Pattern<T,S>	Pattern.subtype(Class<S> subtypeClass)	Applies a subtype constraint on the current pattern.
Pattern<T,F>	Pattern.times(int times)	Specifies exact number of times that this pattern should be matched.
Pattern<T,F>	Pattern.times(int from, int to)	Specifies that the pattern can occur between from and to times.
Pattern<T,F>	Pattern.times(int from, int to, Duration windowTime)	Specifies that the pattern can occur between from and to times with time interval corresponds to the maximum time gap between previous and current event for each times.
Pattern<T,F>	Pattern.times(int times, Duration windowTime)	Specifies exact number of times that this pattern should be matched and time interval corresponds to the maximum time gap between previous and current event for each times.

Pattern<T,F>	GroupPattern.where(IterativeCondition<F> condition)
Pattern<T,F>	Pattern.where(IterativeCondition<F> condition)	Adds a condition that has to be satisfied by an event in order to be considered a match.
Pattern<T,F>	Pattern.within(Duration windowTime)	Defines the maximum time interval in which a matching pattern has to be completed in order to be considered valid.
Pattern<T,F>	Pattern.within(Duration windowTime, WithinType withinType)	Defines the maximum time interval in which a matching pattern has to be completed in order to be considered valid.
