Description

The class of streams over strings.

The contents: init-keyword is used as the input for an input stream, and as the initial storage for an output stream.

The start: init-keyword specifies the start position of the string to be streamed over.

The class supports the same init-keywords as <sequence-stream>.

The start: and end: init-keywords specify the portion of the string to create the stream over: start: is inclusive and end: is exclusive. The default is to stream over the entire string.
