Method Detail

findNonOverlapping

public java.util.List<SequenceMatchResult<T>> findNonOverlapping(java.util.List<? extends T> elements)

Given a sequence, applies our patterns over the sequence and returns all non overlapping matches. When multiple patterns overlaps, matched patterns are selected by the highest priority/score is selected, then the longest pattern, then the starting offset, then the original order

Parameters:

elements - input sequence to match against

Returns:

list of match results that are non-overlapping

findNonOverlapping

public java.util.List<SequenceMatchResult<T>> findNonOverlapping(java.util.List<? extends T> elements,
                                                                 java.util.Comparator<? super SequenceMatchResult> cmp)

Given a sequence, applies our patterns over the sequence and returns all non overlapping matches. When multiple patterns overlaps, matched patterns are selected by order specified by the comparator

Parameters:

elements - input sequence to match against

cmp - comparator indicating order that overlapped sequences should be selected.

Returns:

list of match results that are non-overlapping

findAllNonOverlappingMatchesPerPattern

public java.lang.Iterable<SequenceMatchResult<T>> findAllNonOverlappingMatchesPerPattern(java.util.List<? extends T> elements)

Given a sequence, applies each of our patterns over the sequence and returns all non overlapping matches for each of the patterns. Unlike #findAllNonOverlapping, overlapping matches from different patterns are kept

Parameters:

elements - input sequence to match against

Returns:

iterable of match results that are non-overlapping

getTriggeredPatterns

public java.util.Collection<SequencePattern<T>> getTriggeredPatterns(java.util.List<? extends T> elements)
