BufferStream

Comment in Com46:
- is-a ReadWriteStream on a String
- like a queue
  removeNext:/nextPutAll: protocol

Class protocol:

 on: aString

Instance protocol:

 contents

return contents, non-destructive

 match: aString

 next

return the next character

 next: anInteger

return next anInteger characters

 nextPutAll: aString

(comment from inherited method)
put all elements of the argument, aCollection onto the receiver.
Answer the receiver.
This is only allowed, if the receiver supports writing.

 peek

return the next character without consuming it

 size

(comment from inherited method)
return the number of elements in the streamed collection.

 upTo: aChar

return String up to aChar, but not including

 upToAll: aString

return a string before the occurence of aString, if any

 upToEnd

return buffer contents,
consume all my buffer

 on: aString

 reset

hack

 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.

 includes: aChar

answer whether buffer includes aChar within bounds

 includesAll: aString

answer whether the buffer contains aString

 isEmpty

(comment from inherited method)
return true, if the contents of the stream is empty
