Class Route

io.vertx.reactivex.ext.web.Route

public class Route
extends Object

A route is a holder for a set of criteria which determine whether an HTTP request or failure should be routed to a handler.

Route

public Route(Route delegate)

Route

public Route(Object delegate)

Method Detail

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

getDelegate

public Route getDelegate()

method

public Route method(HttpMethod method)

Add an HTTP method for this route. By default a route will match all HTTP methods. If any are specified then the route will only match any of the specified methods

Parameters:

method - the HTTP method to add

Returns:

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

path

public Route path(String path)

Set the path prefix for this route. If set then this route will only match request URI paths which start with this path prefix. Only a single path or path regex can be set for a route.

Parameters:

path - the path prefix

Returns:

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

pathRegex

public Route pathRegex(String path)

Set the path prefix as a regular expression. If set then this route will only match request URI paths, the beginning of which match the regex. Only a single path or path regex can be set for a route.

Parameters:

path - the path regex

Returns:

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

produces

public Route produces(String contentType)

Add a content type produced by this route. Used for content based routing.

Parameters:

contentType - the content type

Returns:

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

consumes

public Route consumes(String contentType)

Add a content type consumed by this route. Used for content based routing.

Parameters:

contentType - the content type

Returns:

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

order

public Route order(int order)

Specify the order for this route. The router tests routes in that order.

Parameters:

order - the order

Returns:

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

last

public Route last()

Specify this is the last route for the router.

Returns:

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

handler

public Route handler(Handler<RoutingContext> requestHandler)

Append a request handler to the route handlers list. The router routes requests to handlers depending on whether the various criteria such as method, path, etc match. When method, path, etc are the same for different routes, You should add multiple handlers to the same route object rather than creating two different routes objects with one handler for route

Parameters:

requestHandler - the request handler

Returns:

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

blockingHandler

public Route blockingHandler(Handler<RoutingContext> requestHandler)

Like blockingHandler(io.vertx.core.Handler<io.vertx.reactivex.ext.web.RoutingContext>) called with ordered = true

Parameters:

requestHandler -

Returns:

subRouter

public Route subRouter(Router subRouter)

Use a (sub) Router as a handler. There are several requirements to be fulfilled for this to be accepted.

• The route path must end with a wild card
• Parameters are allowed but full regex patterns not
• No other handler can be registered before or after this call (but they can on a new route object for the same path)
• Only 1 router per path object

Parameters:

subRouter - the router to add

Returns:

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

blockingHandler

public Route blockingHandler(Handler<RoutingContext> requestHandler,
                             boolean ordered)

Specify a blocking request handler for the route. This method works just like handler(io.vertx.core.Handler<io.vertx.reactivex.ext.web.RoutingContext>) excepted that it will run the blocking handler on a worker thread so that it won't block the event loop. Note that it's safe to call context.next() from the blocking handler as it will be executed on the event loop context (and not on the worker thread. If the blocking handler is ordered it means that any blocking handlers for the same context are never executed concurrently but always in the order they were called. The default value of ordered is true. If you do not want this behaviour and don't mind if your blocking handlers are executed in parallel you can set ordered to false.

Parameters:

requestHandler - the blocking request handler

ordered - if true handlers are executed in sequence, otherwise are run in parallel

Returns:

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

failureHandler

public Route failureHandler(Handler<RoutingContext> failureHandler)

Append a failure handler to the route failure handlers list. The router routes failures to failurehandlers depending on whether the various criteria such as method, path, etc match. When method, path, etc are the same for different routes, You should add multiple failure handlers to the same route object rather than creating two different routes objects with one failure handler for route

Parameters:

failureHandler - the request handler

Returns:

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

remove

public Route remove()

Remove this route from the router

Returns:

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

disable

public Route disable()

Disable this route. While disabled the router will not route any requests or failures to it.

Returns:

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

enable

public Route enable()

Enable this route.

Returns:

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

useNormalisedPath

public Route useNormalisedPath(boolean useNormalisedPath)

If true then the normalised request path will be used when routing (e.g. removing duplicate /) Default is true

Parameters:

useNormalisedPath - use normalised path for routing?

Returns:

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

getPath

public String getPath()

Returns:

the path prefix (if any) for this route

isRegexPath

public boolean isRegexPath()

Returns true of the path is a regular expression, this includes expression paths.

Returns:

true if backed by a pattern.

methods

public Set<HttpMethod> methods()

Returns:

the http methods accepted by this route

setRegexGroupsNames

public Route setRegexGroupsNames(List<String> groups)

When you add a new route with a regular expression, you can add named capture groups for parameters.
However, if you need more complex parameters names (like "param_name"), you can add parameters names with this function. You have to name capture groups in regex with names: "p0", "p1", "p2", ...

For example: If you declare route with regex \/(?[a-z]*)\/(?[a-z]*) and group names ["param_a", "param-b"] for uri /hello/world you receive inside pathParams() the parameter param_a = "hello"

Parameters:

groups - group names

Returns:

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

newInstance

public static Route newInstance(Route arg)
