```
public class JsonParser
extends Object
implements ReadStream<JsonEvent>, io.vertx.core.Handler<Buffer>, Consumer<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 exceptionHandler(java.util.function.Consumer<java.lang.Throwable>) 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 original non Mutiny-ified interface using Vert.x codegen.

    Specified by:
    
    handle in interface io.vertx.core.Handler<Buffer>
    
    Parameters:
    
    event - the event to handle
  - pipe
```
public Pipe<JsonEvent> pipe()
```
    Specified by:
    
    pipe in interface ReadStream<JsonEvent>
    
    Returns:
    
    a pipe
  - pipeTo
```
@CheckReturnValue
public io.smallrye.mutiny.Uni<Void> pipeTo(WriteStream<JsonEvent> dst)
```
    Pipe this ReadStream to the WriteStream.
    Elements emitted by this stream will be written to the write stream until this stream ends or fails.
    Once this stream has ended or failed, the write stream will be ended and the handler will be called with the result.
    Unlike the bare Vert.x variant, this method returns a Uni. Don't forget to subscribe on it to trigger the operation.
    
    Specified by:
    
    pipeTo in interface ReadStream<JsonEvent>
    
    Parameters:
    
    dst - the destination write stream
    
    Returns:
    
    the uni firing the result of the operation when completed, or a failure if the operation failed.
  - pipeToAndAwait
```
public Void pipeToAndAwait(WriteStream<JsonEvent> dst)
```
    Blocking variant of ReadStream.pipeTo(io.vertx.mutiny.core.streams.WriteStream).
    This method waits for the completion of the underlying asynchronous operation. If the operation completes successfully, the result is returned, otherwise the failure is thrown (potentially wrapped in a RuntimeException).
    
    Specified by:
    
    pipeToAndAwait in interface ReadStream<JsonEvent>
    
    Parameters:
    
    dst - the destination write stream
    
    Returns:
    
    the Void instance produced by the operation.
  - pipeToAndForget
```
public void pipeToAndForget(WriteStream<JsonEvent> dst)
```
    Variant of ReadStream.pipeTo(io.vertx.mutiny.core.streams.WriteStream) that ignores the result of the operation.
    This method subscribes on the result of ReadStream.pipeTo(io.vertx.mutiny.core.streams.WriteStream), but discards the outcome (item or failure). This method is useful to trigger the asynchronous operation from ReadStream.pipeTo(io.vertx.mutiny.core.streams.WriteStream) but you don't need to compose it with other operations.
    
    Specified by:
    
    pipeToAndForget in interface ReadStream<JsonEvent>
    
    Parameters:
    
    dst - the destination write stream
