Translates an unblamed region into one or more blamed regions, using the fully blamed data from cache.

Blamed and unblamed regions are not symmetrical: An unblamed region is just a range of lines over the file. A blamed region is a Candidate (with the commit info) with a region inside (the range blamed).

pack-priv static Region

Returns:

a new region with the intersection.
intersectRegions(Region
a region from the blame generator
unblamed, CacheRegion
a cached region
cached)

Calculate the intersection between a Region and a CacheRegion, adjusting the start if needed.

pack-priv Candidate

Returns:

A linked list of Candidates with their blamed regions, null if there was any error.
mergeCandidate(Candidate
a candidate with a list of unblamed regions
candidate)

Return one or more candidates blaming all the regions of the "unblamed" incoming candidate.

pack-priv List<CacheRegion> findOverlaps(Region unblamed)
intersectRegionsback to summary
pack-priv static Region intersectRegions(Region unblamed, CacheRegion cached)

Calculate the intersection between a Region and a CacheRegion, adjusting the start if needed.

This should be called only if there is an overlap (filtering the cached regions with findOverlaps(Region)), otherwise the result is meaningless.

Parameters
unblamed:Region

a region from the blame generator

cached:CacheRegion

a cached region

Returns:Region

a new region with the intersection.

mergeCandidateback to summary
pack-priv Candidate mergeCandidate(Candidate candidate)

Return one or more candidates blaming all the regions of the "unblamed" incoming candidate.

Parameters
candidate:Candidate

a candidate with a list of unblamed regions

Returns:Candidate

A linked list of Candidates with their blamed regions, null if there was any error.
