openFile

protected void openFile(java.io.File path)

Here we try to be intelligent about opening streams. If the file does not already exist, we assume that we are going to be creating it and writing to it, otherwise we assume that we are going to be reading from it. If you want the other stream open, you must do it explicitly by calling openStreams.

Specified by:

openFile in class AbstractDictionaryFile

Throws:

java.io.IOException
