question: public void rewindToWS ( ) { if ( nextOffset == 0 ) { return ; } nextOffset -- ; while ( nextOffset > 0 && ! Character . isWhitespace ( s . charAt ( nextOffset ) ) ) { nextOffset -- ; } this . offset = nextOffset - 1 ; }
target:  Sets next offset to the next preceeding WS -- this method must not be called during parsing of JSDoc, but only for completion hint!
