6.182 WriteStream
- Defined in namespace Smalltalk
- Category: Streams-Collection
- I am the class of writeable streams. I only allow write operations to
my instances; reading is strictly forbidden.
6.182.1 WriteStream class: instance creation
- on: aCollection
- Answer a new instance of the receiver which streams on aCollection. Every item of aCollection is discarded.
- with: aCollection
- Answer a new instance of the receiver which streams from the end of aCollection.
- with: aCollection from: firstIndex to: lastIndex
- Answer a new instance of the receiver which streams from the firstIndex-th item of aCollection to the lastIndex-th. The pointer is moved to the last item in that range.
6.182.2 WriteStream: accessing
- size
- Answer how many objects have been written
6.182.3 WriteStream: accessing-writing
- nextPut: anObject
- Store anObject as the next item in the receiver. Grow the collection if necessary
6.182.4 WriteStream: positioning
- emptyStream
- Extension - Reset the stream
- position: anInteger
- Skip to the anInteger-th item backwards in the stream. Fail if anInteger>self position. The stream is truncated after the pointer
- skip: anInteger
- Skip (anInteger negated) items backwards in the stream. Fail if anInteger>0. The stream is truncated after the pointer
