In addition to the synchronous proxy method, slice2matlab generates the following asynchronous proxy method:
| Code Block | ||||
|---|---|---|---|---|
| ||||
classdef EmployeesPrx < Ice.ObjectPrx
methods
function result = getName(obj, number, varargin) % Synchronous method
...
end
function future = getNameAsync(obj, number, varargin) % Asynchronous method
...
end
end
...
end |
...
Here's an example that calls getNameAsync:
| Code Block | ||||
|---|---|---|---|---|
| ||||
e = ...; % Get EmployeesPrx proxy future = e.getNameAsync(99); % Continue to do other things here... name = f.fetchOutputs(); |
...
The generated code looks like this:
| Code Block | ||||
|---|---|---|---|---|
| ||||
classdef ExamplePrx < Ice.ObjectPrx
methods
function future = opAsync(obj, inp1, inp2, varargin)
...
end
...
end
...
end |
Now let's call fetchOutputs to demonstrate how to retrieve the results when the invocation completes:
| Code Block | ||||
|---|---|---|---|---|
| ||||
e = ...; % Get EmployeesPrx proxy future = e.opAsync(5, 'demo'); ... [r, outp1, outp2] = future.fetchOutputs(); |
...
The Future object that is returned by asynchronous proxy methods has an API that resembles MATLAB's parallel.Future class:
| Code Block | ||||
|---|---|---|---|---|
| ||||
classdef Future < ...
methods
function ok = wait(obj)
function varargout = fetchOutputs(obj)
function cancel(obj)
end
properties(SetAccess=private) % Read only properties
ID
NumOutputArguments
Operation
Read
State
end
