Parameters:: filePath - Path to the file to parse.
Returns:: A list of DependencyInfo objects.
Throws:: IOException - Thrown if the file could not be read.

parseFile

public List<DependencyInfo> parseFile(String filePath,
                                      String fileContents)

Parses the given file and returns a list of dependency information that it contained. It uses the passed in fileContents instead of reading the file.

Parameters:: filePath - Path to the file to parse.; fileContents - The contents to parse.
Returns:: A list of DependencyInfo objects.

parseFileReader

public List<DependencyInfo> parseFileReader(String filePath,
                                            Reader reader)

Parses the file from the given reader and returns a list of dependency information that it contained.

Parameters:: filePath - Path to the file to parse.; reader - A reader for the file.
Returns:: A list of DependencyInfo objects.

parseLine

protected boolean parseLine(String line)
                     throws com.google.javascript.jscomp.deps.JsFileLineParser.ParseException

Parameters:: line - The line to parse.
Returns:: true to keep going, false otherwise.
Throws:: ParseException - Thrown if the given line has a malformed goog.addDependency().; com.google.javascript.jscomp.deps.JsFileLineParser.ParseException
