The StringObservable class contains methods that represent operators particular to Observables that deal in string-based sequences and streams. These include:

• byLine( ) — converts an Observable of Strings into an Observable of Lines by treating the source sequence as a stream and splitting it on line-endings
• decode( ) — convert a stream of multibyte characters into an Observable that emits byte arrays that respect character boundaries
• encode( ) — transform an Observable that emits strings into an Observable that emits byte arrays that respect character boundaries of multibyte characters in the original strings
• from( ) — convert a stream of characters or a Reader into an Observable that emits byte arrays or Strings
• join( ) — converts an Observable that emits a sequence of strings into an Observable that emits a single string that concatenates them all, separating them by a specified string
• split( ) — converts an Observable of Strings into an Observable of Strings that treats the source sequence as a stream and splits it on a specified regex boundary
• stringConcat( ) — converts an Observable that emits a sequence of strings into an Observable that emits a single string that concatenates them all
