hi All,
Can someone point me to some documentation on fragments and how
they are
used within SCA?
There is some coverage in the 0.9 assembly model spec available here:
http://www.osoa.org/display/Main/SCA+-+Previously+Published
+Specifications
Since then though, fragments have be replaced with the concept of
recursive composition which is described in the 0.95 level spec:
http://www.osoa.org/display/Main/Service+Component+Architecture
+Specifications
and
http://www.osoa.org/display/Main/Recursive+Assembly+Model
Fragments are now just composites that are used by other composites
in one of two ways:
* as implementatation, where a component in a composite is
implemented by a composite. This has benefits in terms of encapsulation.
* by inclusion, where a composite includes services, references and
properties from another which is really a way of just partitioning up
the definition (think #include)
