Class FileBuilder
- java.lang.Object
-
- net.sf.statcvs.input.FileBuilder
-
public class FileBuilder extends java.lang.Object
Builds a
VersionedFile
withRevision
s from logging data. This class is responsible for deciding if a file or revisions will be included in the report, for translating from CVS logfile data structures to the data structures in the net.sf.statcvs.model package, and for calculating the LOC history for the file.A main goal of this class is to delay the creation of the VersionedFile object until all revisions of the file have been collected from the log. We could simply create VersionedFile and Revisions on the fly as we parse through the log, but this creates a problem if we decide not to include the file after reading several revisions. The creation of a VersionedFile or Revision can cause many more objects to be created (Author, Directory, Commit), and it would be very hard to get rid of them if we don't want the file. This problem is solved by first collecting all information about one file in this class, and then, with all information present, deciding if we want to create the model instances or not.

addRevisionData
public void addRevisionData(RevisionData data)

beginOfLogDate
- the date of the begin of the log- Returns:
- a VersionedFile representation of the file.
