6.166 TokenStream

Defined in namespace Smalltalk

Category: Streams-Collections

I am not a typical part of the Smalltalk kernel class hierarchy. I operate on a stream of characters and return distinct whitespace-delimited groups of characters; I am used to parse the parameters of class-creation methods.

Basically, I parse off whitespace separated tokens as substrings and return them (next). If the entire contents of the string are requested, I return them as an Array containing the individual strings.
