Method: Bio::Location#<=>

Defined in:
lib/bio/location.rb

#<=>(other) ⇒ Object

Check where a Bio::Location object is located compared to another Bio::Location object (mainly to facilitate the use of Comparable). A location A is upstream of location B if the start position of location A is smaller than the start position of location B. If they’re the same, the end positions are checked.

Arguments:

  • (required) _other location_: a Bio::Location object

Returns

  • 1 if self < other location

  • -1 if self > other location

  • 0 if both location are the same

  • nil if the argument is not a Bio::Location object
