Class OgnlRouter<InputType>

java.lang.Object

org.chenile.owiz.impl.CommandBase<InputType>

org.chenile.owiz.impl.Router<InputType>

org.chenile.owiz.impl.ognl.OgnlRouter<InputType>

Type Parameters:

InputType - .

All Implemented Interfaces:

AttachableCommand<InputType>, BypassableCommand<InputType>, Command<InputType>, OrchestrationAware<InputType>

public class OgnlRouter<InputType>
extends Router<InputType>

Avoids creation of multiple routers by allowing an expression that can be utilized on the context to obtain the route.

Sample: <router id='xxx' componentName='yyy' expression='a.b'> --- </router>

In the above example, context.getA().getB() would be evaluated to obtain the route. The object obtained from the evaluation is then converted to a string and returned as a routing string which is then used to compute the correct command that can be used.
