| AssignableDataSource<T>::const_reference_t rvalue | ( | ) | const [inline, virtual] |
Get a const reference (or null) to the value of this DataSource.
Getting a reference to an internal data structure is not thread-safe. DataSources which wish to protect their data from concurrent access may return the null reference with this method. All calls to rvalue() must first check whether they do not return null.

| virtual AssignableDataSource<T>::reference_t set | ( | ) | [inline, virtual] |
Get a reference (or null) to the value of this DataSource.
Getting a reference to an internal data structure is not thread-safe. DataSources which wish to protect their data from concurrent access may return the null reference with this method. All calls to set() must first check whether they do not return null.

| virtual AssignableDataSource<T>* clone | ( | ) | const [inline, virtual] |
Return a shallow clone of this DataSource.
This method returns a duplicate of this instance which re-uses the DataSources this DataSource holds reference to. The clone() function is thus a non-deep copy.
Implements AssignableDataSource.
Definition at line 291 of file CORBAExpression.hpp.
| virtual AssignableDataSource<T>* copy | ( | std::map< const DataSourceBase *, DataSourceBase * > & | alreadyCloned | ) | const [inline, virtual] |
Create a deep copy of this DataSource, unless it is already cloned.
Places the association (parent, clone) in alreadyCloned. If the DataSource is non-copyable (for example it represents the Property of a Task ), this may be returned.
Implements AssignableDataSource.

| virtual int serverProtocol | ( | ) | const [inline, virtual] |
Inspect if this DataSource is a proxy for a remote server object.

| bool update | ( | DataSourceBase * | other | ) | [inline, virtual, inherited] |
Update the value of this DataSource with the value of an other DataSource.
Update does a full update of the value, adding extra information if necessary.

| DataSourceBase * | other | |||
| ) | [virtual, inherited] |
Update part of the value of this DataSource with the value of an other DataSource.
Update does a partial update of the value, according to part, which is most likely an index or hash value of some type.

oro_atomic_t refcount [mutable, protected, inherited] |
We keep the refcount ourselves.
We aren't using boost::shared_ptr, because boost::intrusive_ptr is better, exactly because it can be used with refcounts that are stored in the class itself. Advantages are that the shared_ptr's for derived classes use the same refcount, which is of course very much desired, and that refcounting happens in an efficient way, which is also nice :)
