Endpoint Properties

Name Type Required Default Description
name string The name value is not used.
appid string APPID ID used to authenticate the user connected to the API Server
headerName string To store the weather result in this header instead of the message body. This is useable if you want to keep current message body as-is.
language object en Language of the response.
mode object JSON The output format of the weather data.
period string If null, the current weather will be returned, else use values of 5, 7, 14 days. Only the numeric value for the forecast period is actually parsed, so spelling, capitalisation of the time period is up to you (its ignored)
units object The units for temperature measurement.
weatherApi object The API to use (current, forecast/3 hour, forecast daily, station)
sendEmptyMessageWhenIdle boolean false If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead.
bridgeErrorHandler boolean false Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions (if possible) occurred while the Camel consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. Important: This is only possible if the 3rd party component allows Camel to be alerted if an exception was thrown. Some components handle this internally only, and therefore bridgeErrorHandler is not possible. In other situations we may improve the Camel component to hook into the 3rd party component and make this possible for future releases. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.
exceptionHandler object To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.
exchangePattern object Sets the exchange pattern when the consumer creates an exchange.
pollStrategy object A pluggable org.apache.camel.PollingConsumerPollingStrategy allowing you to provide your custom implementation to control error handling usually occurred during the poll operation before an Exchange have been created and being routed in Camel.
lazyStartProducer boolean false Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.
geoLocationProvider object A custum geolocation provider to determine the longitude and latitude to use when no location information is set. The default implementaion uses the ipstack API and requires geolocationAccessKey and geolocationRequestHostIP
httpClient object To use an existing configured http client (for example with http proxy)
cnt integer Number of results to be found
ids string List of id's of city/stations. You can separate multiple ids by comma.
lat string Latitude of location. You can use lat and lon options instead of location. For boxed queries this is the bottom latitude.
location string If null Camel will try and determine your current location using the geolocation of your ip address, else specify the city,country. For well known city names, Open Weather Map will determine the best fit, but multiple results may be returned. Hence specifying and country as well will return more accurate data. If you specify current as the location then the component will try to get the current latitude and longitude and use that to get the weather details. You can use lat and lon options instead of location.
lon string Longitude of location. You can use lat and lon options instead of location. For boxed queries this is the left longtitude.
rightLon string For boxed queries this is the right longtitude. Needs to be used in combination with topLat and zoom.
topLat string For boxed queries this is the top latitude. Needs to be used in combination with rightLon and zoom.
zip string Zip-code, e.g. 94040,us
zoom integer For boxed queries this is the zoom. Needs to be used in combination with rightLon and topLat.
backoffErrorThreshold integer The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in.
backoffIdleThreshold integer The number of subsequent idle polls that should happen before the backoffMultipler should kick-in.
backoffMultiplier integer To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again. When this option is in use then backoffIdleThreshold and/or backoffErrorThreshold must also be configured.
delay integer 500 Milliseconds before the next poll.
greedy boolean false If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages.
initialDelay integer 1000 Milliseconds before the first poll starts.
repeatCount integer 0 Specifies a maximum limit of number of fires. So if you set it to 1, the scheduler will only fire once. If you set it to 5, it will only fire five times. A value of zero or negative means fire forever.
runLoggingLevel object TRACE The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that.
scheduledExecutorService object Allows for configuring a custom/shared thread pool to use for the consumer. By default each consumer has its own single threaded thread pool.
scheduler object none To use a cron scheduler from either camel-spring or camel-quartz component. Use value spring or quartz for built in scheduler
schedulerProperties object To configure additional properties when using a custom scheduler or any of the Quartz, Spring based scheduler.
startScheduler boolean true Whether the scheduler should be auto started.
timeUnit object MILLISECONDS Time unit for initialDelay and delay options.
useFixedDelay boolean true Controls if fixed delay or fixed rate is used. See ScheduledExecutorService in JDK for details.
geolocationAccessKey string The geolocation service now needs an accessKey to be used
geolocationRequestHostIP string The geolocation service now needs to specify the IP associated to the accessKey you're using
