All known Subclasses:   org.apache.beehive.netui.tags.databinding.invoke .CallPageFlow,
CallMethod
public class CallMethod extends AbstractCallMethod (Code)

An abstract base class for tags that are capable of reflectively invoking methods. Specializations of this tag provide method implementations that locate the object on which to invoke the method and that handle any return value from the invoked method.

The CallMethod tag can have child tags of type MethodParameter ; these tags must be in the same order as the parameter list in the method signature of the method that will be invoked. To invoke an overloaded method, the MethodParameter.setType(String) property must be set to the String name of the type to pass to the method. If the type attribute values on nested MethodParameter tags do not match any method signature, an error will be reported in the page.
