Timer Component

The timer: component is used to generate message exchanges when a timer fires You can only consume events from this endpoint.

timer:name?options

Where options is a query string that can specify any of the following parameters:

Name	Default Value	Description
name	null	The name of the Timer object which is created and shared across endpoints. So if you use the same name for all your timer endpoints then only one Timer object & thread will be used
time		The date/time that the (first) event should be generated.
period	-1	If set to greater than 0, then generate periodic events every period milliseconds
delay	-1	The number of milliseconds to wait before the first event is generated. Should not be used in conjunction with the time parameter.
fixedRate	false	Events take place at approximately regular intervals, separated by the specified period.
daemon	true	Should the thread associated with the timer endpoint be run as a daemon.

When the timer is fired it adds the following information as properties to the Exchange.

Name	Type	Description
org.apache.camel.timer.name	String	the name option
org.apache.camel.timer.time	Date	the time option
org.apache.camel.timer.period	long	the period option
org.apache.camel.timer.firedtime	Date	Camel 1.5: the current time when the consumer fired

To setup a route that generates an event every 60 seconds:

from("timer://foo?fixedRate=true&delay=0&period=60000").to("bean:myBean?methodName=someMethodName");

The above route will generate an event then invoke the someMethodName on the bean called myBean in the Registry such as JNDI or Spring.
