Method Detail

init

public void init()

enableResourceLogging

public void enableResourceLogging(boolean resourceLoggingEnabled)

Specified by:

enableResourceLogging in interface org.swisspush.gateleen.core.logging.LoggableResource

handle

public boolean handle(io.vertx.core.http.HttpServerRequest request)

Handles requests, which are either listener or route related. Takes on:

• hook un-/registration
• enqueueing a request for the registred listeners
• forwarding a request to the reistred listeners
• creating a self request for the original request (if necessary)

Parameters:

request - request

Returns:

true if a request is processed by the handler, otherwise false

isRequestAlreadyHooked

public boolean isRequestAlreadyHooked(io.vertx.core.http.HttpServerRequest request)

Checks if the original Request was already hooked. Eg. After a request is processed by the hook handler (register), the handler creates a self request with a copy of the original request. Therefore it's necessary to mark the request as already hooked.

Parameters:

request - request

Returns:

true if the original request was already hooked.

getUniqueListenerId

protected java.lang.String getUniqueListenerId(java.lang.String requestUrl)

Creates a listener id, which is unique for the given service, and the monitored url.

Parameters:

requestUrl - requestUrl

Returns:

String
