Class CdiSpiDecorator

  • All Implemented Interfaces:
    Decorator
    public class CdiSpiDecorator
extends java.lang.Object
implements Decorator
    A Decorator that invokes the CDI provider within a webapp to decorate objects created by the contexts DecoratedObjectFactory (typically Listeners, Filters and Servlets). The CDI provider is invoked using MethodHandles to avoid any CDI instance or dependencies within the server scope. The code invoked is equivalent to: 
     public <T> T decorate(T o)
 {
   BeanManager manager = CDI.current().getBeanManager();
   manager.createInjectionTarget(manager.createAnnotatedType((Class<T>)o.getClass()))
     .inject(o,manager.createCreationalContext(null));
   return o;
 }

    • Method Detail

      • isDecoratable

        protected boolean isDecoratable​(java.lang.Class<?> clazz)
        Test if a class can be decorated. The default implementation checks the set from getUndecoratable() on the class and all it's super classes.
        Parameters:
        clazz - The class to check
        Returns:
        True if the class and all it's super classes can be decorated

      • getUndecoratable

        public java.util.Set<java.lang.String> getUndecoratable()
        Get the set of classes that will not be decorated. The default set includes the listener from Weld that will itself setup decoration.
        Returns:
        The modifiable set of class names that will not be decorated (ie isDecoratable(Class) will return false.
        See Also:
        isDecoratable(Class)

      • setUndecoratable

        public void setUndecoratable​(java.util.Set<java.lang.String> classnames)
        Parameters:
        classnames - The set of class names that will not be decorated.
        See Also:
        isDecoratable(Class)

      • addUndecoratable

        public void addUndecoratable​(java.lang.String... classname)
        Parameters:
        classname - A class name that will be added to the undecoratable classes set.
        See Also:
        getUndecoratable(), isDecoratable(Class)
