Public Instance Methods

collect() click to toggle source

Waits for the operation to finish and returns both its completion status and, if applicable, its return value(s)

Existing completion status are

Orocos::SEND_SUCCESS
Orocos::SEND_NOT_READY
Orocos::SEND_FAILURE

# File lib/orocos/operations.rb, line 16
def collect
    CORBA.refine_exceptions(self) do
        status = do_operation_collect(orocos_return_types, return_values)
        if return_values.empty?
            return status
        else
            return [status, *return_values]
        end
    end
end

collect_if_done() click to toggle source

Returns the current status for the operation

If the operation is finished, and if it has a return value, then it returns

Orocos::SEND_SUCCESS, return_value1, return_value2, ...

Otherwise, returns either Orocos::SEND_NOT_READY (not yet processed) or Orocos::SEND_FAILURE (operation failed to be processed on the remote task)
