intersects

public static boolean intersects(List<Span> spans1,
                                 List<Span> spans2)

spansMatch

public static boolean spansMatch(List<Span> spans1,

merge

public static Span merge(Span span1,
                         Span span2)

This method takes two spans that intersect and returns a Span that "merges" the two spans. The start of the returned span is the minimum of span1.getStart and span2.getStart. The end of the returned span is the maximum of span1.getEnd and span2.getEnd

Parameters:

span1 -

span2 -

Returns:

null if the two spans do not intersect

substring

public static String substring(String string,
                               Span span)
