Detailed Description

A template-less SendHandle manager.

It is created using a SendHandle data source, obtained from a OperationFactoryPart::produceSend(), the part itself and any arguments that must be provided to collect the results.

It is used by OperationCallerC to pass on responsibility to collect results to a separate object.

Definition at line 61 of file SendHandleC.hpp.


Constructor & Destructor Documentation

The default constructor.

Make a copy from another SendHandleC object in order to make it usable.

The constructor from a SendHandle data source and an operation part.

The SendHandle is obtained after a send.


Member Function Documentation

Add a datasource argument to the SendHandle.

Parameters:
aA DataSource which contents are filled in in case of collect() or collectIfDone()
template<class ArgT >
SendHandleC& RTT::internal::SendHandleC::arg ( ArgT &  a) [inline]

Add an argument by reference to the OperationCaller.

Parameters:
aA value of which the reference is used and re-read each time the method is called. Thus if the contents of the source of a changes, call() will use the new contents.

Definition at line 115 of file SendHandleC.hpp.

Checks if this handle is ready for collecting, will throw if not so.

Otherwise, does nothing.

Exceptions:
invalid_handle_exception
wrong_number_of_args_exception
wrong_types_of_args_exception

When set to 'on', the destruction of this SendHandleC will cause a call to collect() before all data in data sources is destroyed.

This is required for in-process operation calls, since destruction of the data sources would lead to memory corruption of the operation's arguments. When set to 'off', no such collection is done, which is useful in remote/inter-process communication, in which the data lives in a copy in the other process anyway. Since RTT uses this same class for both situations, we need a flag to distinguish.

Defaults to 'on', which is the safe default if unspecified.
