[jira] Updated: (TUSCANY-1341) Callback over WS Binding is not
functioning various issues
[ https://issues.apache.org/jira/browse/TUSCANY-1341?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Simon Nash updated TUSCANY-1341:
--------------------------------
Attachment: jira1341-patch1
Because my patch for supporting callbacks across the Web Service binding is quite large, I am splitting it into a series of smaller patches to make it easier to apply.
The first of these patches adds some methods to ReferenceBindingProvider and ServiceBinding Provider. At present I have have placed default implementations of the new methods in all the affected places. These will be replaced by fully implemented versions later. The code to call these new methods will be added in the next stages of this multi-part patch.
I have rebuilt the trunk with this patch and everything seems OK. Since the new code isn't being called yet, there should be no effect (either good or bad) at this stage.
Here is a brief description of the new methods:
ReferenceBindingProvider.createInvoker(Operation) is a replacement for the current method of the same name that also has a boolean isCallback parameter. This second parameter is no longer needed because binding callback invokers will be created using the new method ServiceBindingProvider.createCallbackInvoker(Operation) instead.
The supportsAsyncOneWayInvocation() method on ReferenceBindingProvider indicates whether the provider supports non-blocking semantics for one-way forward invocations.
The supportsAsyncOneWayInvocation() method on ServiceBindingProvider indicates whether the provider supports non-blocking semantics for one-way callback invocations.
The ServiceBindingProvider.createCallbackInvoker(Operation) method creates a callback invoker for the binding.
