Getting Metadata

From the manipulation metadata, you can query manipulation information by using following methods:

...

You often need to invoke method on the POJO objects. iPOJO provides an helper class, named Callback, allow you to manage this invocation easily. You can obtain a Callback object from the Method Metadata. By this way, you are sure that the method exists in the implementation. To create the callback, use the following code:

    ManipulationMetadata manip = new ManipulationMetadata(metadata);
    MethodMetadata method = manip.getMethod("your_method_name");
    Callback cb = new Callback(method, im);

Then you can directly invoke your method:

    ...
	    Object[] args = ...;   // Build your argument array
	    cb.call(args);
	    ...
