# JsonParser

`open class JsonParser : ReadStream<JsonEvent>, 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.reactivex.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. NOTE: This class has been automatically generated from the io.vertx.core.parsetools.JsonParser non RX-ified interface using Vert.x codegen.

### Constructors

<init> | `JsonParser(delegate: JsonParser)`

### Properties

__TYPE_ARG | `static val __TYPE_ARG: TypeArg<JsonParser>`

### Functions

arrayEventMode | `open fun arrayEventMode(): JsonParser` Flip the parser to emit a stream of events for each new json array.
arrayValueMode | `open fun arrayValueMode(): JsonParser` Flip the parser to emit a single value event for each new json array. Json array currently streamed won't be affected.
end | `open fun end(): Unit` End the stream, this must be called after all the json stream has been processed.
endHandler | `open fun endHandler(endHandler: Handler<Void>): JsonParser`
equals | `open fun equals(other: Any?): Boolean`
exceptionHandler | `open fun exceptionHandler(handler: Handler<Throwable>): JsonParser`
getDelegate | `open fun getDelegate(): JsonParser`
handle | `open fun handle(event: Buffer): Unit` Something has happened, so handle it.
handler | `open fun handler(handler: Handler<JsonEvent>): JsonParser`
hashCode | `open fun hashCode(): Int`
newInstance | `open static fun newInstance(arg: JsonParser): JsonParser`
newParser | `open static fun newParser(): JsonParser` `open static fun newParser(stream: ReadStream<Buffer>): JsonParser` `open static fun newParser(stream: Flowable<Buffer>): JsonParser` `open static fun newParser(stream: Observable<Buffer>): JsonParser` Create a new `JsonParser` instance.
objectEventMode | `open fun objectEventMode(): JsonParser` Flip the parser to emit a stream of events for each new json object.
objectValueMode | `open fun objectValueMode(): JsonParser` Flip the parser to emit a single value event for each new json object. Json object currently streamed won't be affected.
pause | `open fun pause(): JsonParser`
resume | `open fun resume(): JsonParser`
toFlowable | `open fun toFlowable(): Flowable<JsonEvent>`
toObservable | `open fun toObservable(): Observable<JsonEvent>`
toString | `open fun toString(): String`
write | `open fun write(buffer: Buffer): JsonParser` Handle a `Buffer`, pretty much like calling io.vertx.reactivex.core.Handler#handle.
