class JsonParser extends ReadStream[JsonEvent] with Handler[Buffer]

A parser class which allows to incrementally parse json elements and emit json parse events instead of parsing a json element fully. This parser is convenient for parsing large json structures.

The parser also parses concatenated json streams or line delimited json streams.

The parser can also parse entire object or array when it is convenient, for instance a very large array of small objects can be parsed efficiently by handling array start/end and object events.

Whenever the parser fails to parse or process the stream, the io.vertx.scala.core.parsetools.JsonParser#exceptionHandler is called with the cause of the failure and the current handling stops. After such event, the parser should not handle data anymore.

    Flip the parser to emit a stream of events for each new json array.

    a reference to this, so the API can be used fluently

  5. def arrayValueMode(): JsonParser

    Flip the parser to emit a single value event for each new json array.

    Flip the parser to emit a single value event for each new json array.

    Json array currently streamed won't be affected.
