boolean intersects(Span r)

isSubspan

boolean isSubspan(Span r)

Returns an integer index identifying the start of this span. Beware that in some cases (e.g., for images), this may not correspond directly to a sequence index.

getEndIdx

int getEndIdx()

Returns an integer index identifying the end of this span. Beware that in some cases (e.g., for images), this may not correspond directly to a sequence index.
