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.
