## Class Builder

- java.lang.Object
- - net.sf.statcvs.input.Builder

All Implemented Interfaces:
  CvsLogBuilder

    public class Builder
    extends java.lang.Object
    implements CvsLogBuilder

Helps building the `Repository` from a CVS log. The `Builder` is fed by some CVS history data source, for example a CVS log parser. The `Repository` can be retrieved using the `createCvsContent()` method.

The class also takes care of the creation of `Author` and Directory objects and makes sure that there's only one of these for each author name and path. It also provides LOC count services.

### Constructor Detail

#### Builder

    public Builder(RepositoryFileManager repositoryFileManager,
           FilePatternMatcher includePattern,
           FilePatternMatcher excludePattern,
           java.util.regex.Pattern tagsPattern)

Creates a new `Builder`

Parameters:
  `repositoryFileManager` - the `RepositoryFileManager` that can be used to retrieve LOC counts for the files that this builder will create
  `includePattern` - a list of Ant-style wildcard patterns, seperated by : or ;
  `excludePattern` - a list of Ant-style wildcard patterns, seperated by : or ;
  `tagsPattern` - A regular expression; matching symbolic names are recorded

### Method Detail

#### clean

    public void clean()

#### buildModule

    public void buildModule(java.lang.String moduleName)

Starts building the module.

Specified by:
  `buildModule` in interface `CvsLogBuilder`
Parameters:
  `moduleName` - name of the module

#### buildFile

    public void buildFile(java.lang.String filename,
                 boolean isBinary,
                 boolean isInAttic,
                 java.util.Map revBySymnames)

Starts building a new file. The files are not expected to be created in any particular order.

Specified by:
  `buildFile` in interface `CvsLogBuilder`
Parameters:
  `filename` - the file's name with path, for example "path/file.txt"
  `isBinary` - `true` if it's a binary file
  `isInAttic` - `true` if the file is dead on the main branch
  `revBySymnames` - maps revision (string) by symbolic name (string)

#### buildRevision

    public void buildRevision(RevisionData data)

Adds a revision to the current file. The revisions must be added in CVS logfile order, that is starting with the most recent one.

Specified by:
  `buildRevision` in interface `CvsLogBuilder`
Parameters:
  `data` - the revision

#### createCvsContent

    public Repository createCvsContent()

Returns a Repository object of all files.

Returns:
  Repository a Repository object

#### getProjectName

    public java.lang.String getProjectName()

#### getAtticFileNames

    public java.util.Set getAtticFileNames()

Returns the `Set` of filenames that are "in the attic".

Returns:
  a `Set` of `String`s

#### allRejectedByExcludePattern

    public boolean allRejectedByExcludePattern()

Returns:
  `true` if there was an exclude pattern, and it rejected all files

#### allRejectedByIncludePattern

    public boolean allRejectedByIncludePattern()

Returns:
  `true` if there was an include pattern, and it rejected all files

#### isLogAndLocalFilesOutOfSync

    public boolean isLogAndLocalFilesOutOfSync()

Returns `true` if the local working copy is out of sync with the log. The current implementation spots if local files have been deleted and not yet committed, or if the log file was generated before the latest commit.

#### isLocalFilesNotFound

    public boolean isLocalFilesNotFound()

Returns `true` if no local copy was found for the majority of files in the log. This is a strong indication that the log is not for the specified local working copy.

#### hasLocalCVSMetadata

    public boolean hasLocalCVSMetadata()

Returns `true` if at least some local files have matching entries in local CVS metada directories. If this is not the case, then the local copy is probably just an export, not a checkout, and we can't check if the log and working copy are in sync.

#### getAuthor

    public Author getAuthor(java.lang.String name)

returns the `Author` of the given name or creates it if it does not yet exist. Author names are handled as case-insensitive.

Parameters:
  `name` - the author's name
Returns:
  a corresponding `Author` object

#### getDirectory

    public Directory getDirectory(java.lang.String filename)

Returns the `Directory` of the given filename or creates it if it does not yet exist.

Parameters:
  `filename` - the name and path of a file, for example "src/Main.java"
Returns:
  a corresponding `Directory` object

#### getSymbolicName

    public SymbolicName getSymbolicName(java.lang.String name)

Returns the `SymbolicName` with the given name or creates it if it does not yet exist.

Parameters:
  `name` - the symbolic name's name
Returns:
  the corresponding symbolic name object

#### getLOC

    public int getLOC(java.lang.String filename)
               throws NoLineCountException

Throws:
  `NoLineCountException`

#### getRevision

    public java.lang.String getRevision(java.lang.String filename)
                                 throws java.io.IOException

Throws:
  `java.io.IOException`
See Also:
  `RepositoryFileManager.getRevision(String)`

#### matchesPatterns

    public boolean matchesPatterns(java.lang.String filename)

Matches a filename against the include and exclude patterns. If no include pattern was specified, all files will be included. If no exclude pattern was specified, no files will be excluded.

Parameters:
  `filename` - a filename
Returns:
  `true` if the filename matches one of the include patterns and does not match any of the exclude patterns. If it matches an include and an exclude pattern, `false` will be returned.
