RoutingContext (Vert.x Stack - Docs 4.5.11 API)

java.lang.Object
- io.vertx.reactivex.ext.web.RoutingContext

```
public class RoutingContext
extends Object
```
Represents the context for the handling of a request in Vert.x-Web.
A new instance is created for each HTTP request that is received in the Handler of the router.
The same instance is passed to any matching request or failure handlers during the routing of the request or failure.
The context provides access to the and and allows you to maintain arbitrary data that lives for the lifetime of the context. Contexts are discarded once they have been routed to the handler for the request.
The context also provides access to the Session, cookies and body for the request, given the correct handlers in the application.
If you use the internal error handler
NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.

```
public HttpServerResponse response()
```
    Returns:
    
    the HTTP response object
  - next
```
public void next()
```
    Tell the router to route this context to the next matching route (if any). This method, if called, does not need to be called during the execution of the handler, it can be called some arbitrary time later, if required.
    If next is not called for a handler then the handler should make sure it ends the response or no response will be sent.
  - fail
```
public void fail(int statusCode)
```
    Fail the context with the specified status code.
    This will cause the router to route the context to any matching failure handlers for the request. If no failure handlers match It will trigger the error handler matching the status code. You can define such error handler with Router.errorHandler(int, io.vertx.core.Handler<io.vertx.reactivex.ext.web.RoutingContext>). If no error handler is not defined, It will send a default failure response with provided status code.
    
    Parameters:
    
    statusCode - the HTTP status code
  - fail
```
public void fail(Throwable throwable)
```
    Fail the context with the specified throwable and 500 status code.
    This will cause the router to route the context to any matching failure handlers for the request. If no failure handlers match It will trigger the error handler matching the status code. You can define such error handler with Router.errorHandler(int, io.vertx.core.Handler<io.vertx.reactivex.ext.web.RoutingContext>). If no error handler is not defined, It will send a default failure response with 500 status code.
    
    Parameters:
    
    throwable - a throwable representing the failure
  - fail
```
public void fail(int statusCode,
                 Throwable throwable)
```
    Fail the context with the specified throwable and the specified the status code.
    This will cause the router to route the context to any matching failure handlers for the request. If no failure handlers match It will trigger the error handler matching the status code. You can define such error handler with Router.errorHandler(int, io.vertx.core.Handler<io.vertx.reactivex.ext.web.RoutingContext>). If no error handler is not defined, It will send a default failure response with provided status code.
    
    Parameters:

    the data
  - get
```
public <T> T get(String key,
                 T defaultValue)

    Parameters:
    
    key - the key for the data
    
    defaultValue - when the underlying data doesn't contain the key this will be the return value.
    
    Returns:
    
    the data
  - remove
```
public <T> T remove(String key)
```
    Remove some data from the context. The data is available in any handlers that receive the context.

  - mountPoint
```
public String mountPoint()

    Returns:
    
    the mount point for this router. It will be null for a top level router. For a sub-router it will be the path at which the subrouter was mounted.

```
public Route currentRoute()
```
    Returns:
    
    the current route this context is being routed through.
  - normalisedPath

    Returns:

```
public String normalizedPath()
```
    Return the normalized path for the request.
    The normalized path is where the URI path has been decoded, i.e. any unicode or other illegal URL characters that were encoded in the original URL with `%` will be returned to their original form. E.g. `%20` will revert to a space. Also `+` reverts to a space in a query.
    The normalized path will also not contain any `..` character sequences to prevent resources being accessed outside of the permitted area.
    It's recommended to always use the normalized path as opposed to if accessing server resources requested by a client.

    Parameters:
    
    handler - the handler
    
    Returns:
    
    the id of the handler. This can be used if you later want to remove the handler.

  - addBodyEndHandler
```
public int addBodyEndHandler(Handler<Void> handler)
```
    Provides a handler that will be called after the last part of the body is written to the wire. The handler is called asynchronously of when the response has been received by the client. This provides a hook allowing you to do more operations once the request has been sent over the wire. Do not use this for resource cleanup as this handler might never get called (e.g. if the connection is reset).
    
    Parameters:
    
    handler - the handler
    
    Returns:
    
    the id of the handler. This can be used if you later want to remove the handler.

    Remove a body end handler
    
    Parameters:
    
    handlerID - the id as returned from addBodyEndHandler(io.vertx.core.Handler<java.lang.Void>).
    
    Returns:
    
    true if the handler existed and was removed, false otherwise
  - addEndHandler
```
public int addEndHandler(Handler<AsyncResult<Void>> handler)
```
    Add an end handler for the request/response context. This will be called when the response is disposed or an exception has been encountered to allow consistent cleanup. The handler is called asynchronously of when the response has been received by the client.
    
    Parameters:
    
    handler - the handler that will be called with either a success or failure result.
    
    Returns:
    
    the id of the handler. This can be used if you later want to remove the handler.
  - removeEndHandler

    Restarts the current router with a new method and path. All path parameters are then parsed and available on the params list. Query params will also be allowed and available.
    
    Parameters:
    
    method - the new http request
    
    path - the new http path.
  - acceptableLanguages
```
public List<LanguageHeader> acceptableLanguages()
```
    Returns the languages for the current request. The languages are determined from the Accept-Language header and sorted on quality. When 2 or more entries have the same quality then the order used to return the best match is based on the lowest index on the original list. For example if a user has en-US and en-GB with same quality and this order the best match will be en-US because it was declared as first entry by the client.
    
    Returns:
    
    The best matched language for the request
  - preferredLanguage
```
public LanguageHeader preferredLanguage()
```

  - queryParams
```
public MultiMap queryParams()

```
public MultiMap queryParams(Charset encoding)
```
    Always decode the current query string with the given encoding. The decode result is never cached. Callers to this method are expected to cache the result if needed. Usually users should use queryParams(). This method is only useful when the requests without content type (GET requests as an example) expect that query params are in the ASCII format ISO-5559-1.
    
    Parameters:
    
    encoding - a non null character set.
    
    Returns:
    
    the multimap of query parameters
