Efficient lookup of query positions in a collection of target sequence
locations where positions and locations are associated with specific
sequence names. This is an extension of
LocMap to use locations and
positions on named sequences as in
Location lookup maps for named sequences
A data structure for efficiently finding target sequence
SeqLoc.Loc) that overlap query positions or locations.
Each target location can be associated with an arbitrary additional
value in the lookup map.
SeqLocMap from a list of target locations and their
Modifying location lookup maps
Inserts a new target location and associated object into the location lookup map.
Searching for target locations
Find the (possibly empty) list of target locations and associated
objects that contain a sequence position, in the sense of
