Description:


there is only one instance of this class: EOF,
representing an EOF token.

This is mainly present for stream-pipe processing,
and may be used to signal the end of a stream.

Smalltalk code does not normally use it.


Class protocol:

class initialization
o  initialize
(comment from inherited method)
called only once - initialize signals

instance creation
o  basicNew
EOFObject basicNew
EOFObject new


Instance protocol:

printing & storing
o  printOn: aStream
(comment from inherited method)
append a user printed representation of the receiver to aStream.
The format is suitable for a human - not meant to be read back.

The default here is to output the receiver's class name.
BUT: this method is heavily redefined for objects which
can print prettier.
