FileUtil

class FileUtil extends AnyRef

This class serves two main purposes:

It might make sense to split these two purposes out into separate classes, but that's not a big deal to me right now, so they will stay as they are. There's also some overlap - if this were two classes, the one that does file manipulation would need to call the file system interface.

    The file is assumed to be a series of lines, one string per line.

    The file is assumed to be a series of lines, one string per line. If the provided dictionary is null, we parse the string to an integer before adding it to a list. Otherwise, we look up the string in the dictionary to convert the string to an integer.

    Reads a tab-separated file and puts the contents into a map.

    Reads a tab-separated file and puts the contents into a map.

    We give a few options: - You can set the index for the key to the map. If the key is not zero, we only add the first column as a value to this map (and so setting overwrite to true in this case doesn't make a whole lot of sense - just use readMapFromTsv instead). - If overwrite is true, we don't bother checking to see if the key is already in the map. This will speed up the processing if you know that your file only has one line per unique key. - You can provide a LineFilter object that wlil be called with each line to determine if it should be skipped.
