-/**
- * run/continue a lex. "offset" is an input/output parameter.
- * It should be initialized to zero for a
- * new chunk of target text, and upon subsetquent calls with the same
- * target text should passed with the value of the previous invocation.
- *
- * the client may be interested in the value of offset when an error is
- * returned from the lexer. This allows the client to render useful
-n * error messages.
- *
- * When you pass the next chunk of data, context should be reinitialized
- * to zero.
- *
- * Finally, the output buffer is usually just a pointer into the jsonText,
- * however in cases where the entity being lexed spans multiple chunks,
- * the lexer will buffer the entity and the data returned will be
- * a pointer into that buffer.
- *
- * This behavior is abstracted from client code except for the performance
- * implications which require that the client choose a reasonable chunk
- * size to get adequate performance.
