Matthew T. Adams updated JDO-638:
---------------------------------
Attachment: InstanceCallbackAnnotations-3.patch
The following proposes the ordering of annotated methods. I've added an order
property to each of the annotations with javadoc as follows:
/**
* The order of execution of this method relative to other annotated
* callback methods. A lower order value means that the annotated
method has
* a higher precedence among annotated methods, and a higher order, a
lower
* precedence. Order values need not be contiguous among annotated
methods.
* Methods that are implementations of the corresponding callback
interface
* method are always called first. The order value {...@link
Integer#MAX_VALUE}
* , the default, signifies that the order is undefined among annotated
* methods. If other annotated methods define an order, those methods
will
* be called before annotated methods with an undefined order. If other
* annotated methods define equal order values, then methods annotated
with
* lower order values will be called before them, the methods with equal
* order values will be called in an undefined order, and then any
methods
* with higher order values will be called after the methods with equal
* order values have been called. If a method that represents an
* implementation of the corresponding interface method carries this
* annotation, the annotation and its order are ignored, and the
interface
* method is called first. If a subclass annotates a method with the
same
* order as an annotated method in its superclass hierarchy, then the
* subclass's method is called first, otherwise the order values among
all
* annotated methods in the class and its superclass hierarchy determine
* call order.

int order() default Integer.MAX_VALUE;
