isOpen

public boolean isOpen()

Description copied from interface: DictionaryFile

Return true if the file is open

Specified by:

isOpen in interface DictionaryFile

close

public void close()

Description copied from interface: DictionaryFile

Close the file

Specified by:

close in interface DictionaryFile

openStreams

                         ClassNotFoundException

Description copied from interface: ObjectDictionaryFile

Read and deserialize an object from the file

Specified by:

readObject in interface ObjectDictionaryFile

Throws:

IOException

ClassNotFoundException

writeObject

public void writeObject(Object obj)
                 throws IOException

Description copied from interface: ObjectDictionaryFile

Serialize and write an object ot the file.

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:

IOException
