singleMessagesFile - the messages file if there is only one, otherwise: null

Method Detail

addKeyOccurrence

public void addKeyOccurrence(KeyOccurrence occ)

Add a key occurrence to the list of occurrences. The list is kept sorted on key and message package. If the key already exists, we increment the number of occurrences.

Parameters:

occ - The key occurrence to add

crawl

public void crawl()
           throws Exception

Throws:

Exception

crawlSourceDirectories

public void crawlSourceDirectories()
                            throws Exception

Throws:

Exception

crawlXmlFolders

protected void crawlXmlFolders()

                              throws IOException

Look for occurrences of keys in the specified file.

Parameters:

sourceFolder - The folder the java file and messages files live in

javaFile - The java source file to examine

Throws:

IOException - In case there is a problem accessing the specified source file.
