Examples of org.apache.openejb.jee.InterceptorBinding

org.apache.openejb.jee.InterceptorBinding
The interceptor-bindingType element describes the binding of interceptor classes to beans within the ejb-jar. It consists of :
- An optional description. - The name of an ejb within the ejb-jar or the wildcard value "*", which is used to define interceptors that are bound to all beans in the ejb-jar. - A list of interceptor classes that are bound to the contents of the ejb-name element or a specification of the total ordering over the interceptors defined for the given level and above. - An optional exclude-default-interceptors element. If set to true, specifies that default interceptors are not to be applied to a bean-class and/or business method. - An optional exclude-class-interceptors element. If set to true, specifies that class interceptors are not to be applied to a business method. - An optional set of method elements for describing the name/params of a method-level interceptor.
Interceptors bound to all classes using the wildcard syntax "*" are default interceptors for the components in the ejb-jar. In addition, interceptors may be bound at the level of the bean class (class-level interceptors) or business methods (method-level interceptors ).
The binding of interceptors to classes is additive. If interceptors are bound at the class-level and/or default-level as well as the method-level, both class-level and/or default-level as well as method-level will apply.
There are four possible styles of the interceptor element syntax :
1. * INTERCEPTOR
Specifying the ejb-name as the wildcard value "*" designates default interceptors (interceptors that apply to all session and message-driven beans contained in the ejb-jar).
2. EJBNAME INTERCEPTOR
This style is used to refer to interceptors associated with the specified enterprise bean(class-level interceptors).
3. EJBNAME INTERCEPTOR METHOD
This style is used to associate a method-level interceptor with the specified enterprise bean. If there are multiple methods with the same overloaded name, the element of this style refers to all the methods with the overloaded name. Method-level interceptors can only be associated with business methods of the bean class. Note that the wildcard value "*" cannot be used to specify method-level interceptors.
4. EJBNAME INTERCEPTOR METHOD PARAM-1 PARAM-2 ... PARAM-N
... This style is used to associate a method-level interceptor with the specified method of the specified enterprise bean. This style is used to refer to a single method within a set of methods with an overloaded name. The values PARAM-1 through PARAM-N are the fully-qualified Java types of the method's input parameters (if the method has no input arguments, the method-params element contains no method-param elements). Arrays are specified by the array element's type, followed by one or more pair of square brackets (e.g. int[][]).
