public interface PostPut implements Annotation
Identifies a callback method to be invoked after an Entity of any of the specified kinds
is written to the datastore. If #kinds() is not provided the callback will execute for
all kinds. Methods with this annotation must return
void, must accept a single argument
of type PutContext, must not throw any checked exceptions, must not be static, and must
belong to a class with a no-arg constructor. Neither the method nor the no-arg constructor of the
class to which it belongs are required to be public. Methods with this annotation are free to
throw any unchecked exception they like. Throwing an unchecked exception will prevent callbacks
that have not yet been executed from running, and the exception will propagate to the code that
invoked the datastore operation that resulted in the invocation of the callback. Throwing an
unchecked exception from a callback will not have any impact on the result of the
datastore operation. Methods with this annotation will not be invoked if the datastore operation
