Class RepositoryFileManager

java.lang.Object

net.sf.statsvn.input.RepositoryFileManager

public class RepositoryFileManager
extends java.lang.Object

Manages a checked-out repository and provides access to line number counts for repository files. New in StatSVN: Also provides a central point of access to abstract out calls to the server. Many of the methods here simply redirect to the static util/SvnXXXUtils classes. Therefore, clients don't have to know where the information is located, they can simply invoke this class.

existsInWorkingCopy

public boolean existsInWorkingCopy(java.lang.String relativePath)

Returns true if the file exists in the working copy (according to the svn metadata, and not file system checks).

Parameters:

relativePath - the path

Returns:

true if it exists

getLineCount

protected int getLineCount(java.io.BufferedReader reader)
                    throws java.io.IOException

Counts lines on a BufferedReader

Parameters:

reader - the buffered reader

Returns:

the number of lines read

Throws:

java.io.IOException - error reading from reader

getLineDiff

public int[] getLineDiff(java.lang.String oldRevNr,
                         java.lang.String newRevNr,
                         java.lang.String filename)
                  throws java.io.IOException,
                         BinaryDiffException

Returns line count differences between two revisions of a file.

Parameters:

oldRevNr - old revision number

newRevNr - new revision number

filename - the filename

Returns:

A int[2] array of [lines added, lines removed] is returned.

Throws:

java.io.IOException - problem parsing the stream

Returns line count differences for all files in a particular revision.

Parameters:

newRevNr - new revision number

Returns:

A vector of object[3] array of [filename, int[2](lines added, lines removed), isBinary] is returned.

Throws:

java.io.IOException - problem parsing the stream
