Hi there,
is the "XNameAccess" interface implied, if a service object defines (and
is defined to have) the interfaces "com.sun.star.container.XIndexAccess"
and/or "com.sun.star.container.XEnumerationAccess"? If so, what would be
the rules to apply?
Reason of this question being, that the service
"com.sun.star.table.TableCharts" (implemented by "ScChartsObj") does not
list "XNameAccess" (nor is it reflected), yet one can use that interface!
If an object O states that it implements service S, and S does not
include a given interface X, O may still implement X. The only
properties that should hold are:
1 If object O states
(XServiceInfo.supportsService/XServiceInfo.getSupportedServiceNames)
that it implements service S, and interface X is non-optionally included
in S, directly or indirectly via the inclusion of sub-services in the
case of old-style services, then O must implement (queryInterace) X, and
O must state (XTypeProvider.getTypes) that it implements X or an
interface Y for which X is a non-optional direct or indirect base.
2 If object O states (XTypeProvider.getTypes) that it implements
interface X, then O must implement (queryInterface) X.
3 If object O implmements (queryInterface) X, and interface Y is a
non-optional direct base of X, then O must implement (queryInterface) Y.
That said, there probably are cases where an interface X that logically
belongs to a service S has erroneously been omitted from S.

Here the service object:
xTableCharts: SERVICE|com.sun.star.table.TableCharts|ScChartsObj
com.sun.star.table.XTableCharts|INTERFACE||com.sun.star.table.TableCharts
com.sun.star.container.XIndexAccess|INTERFACE||com.sun.star.table.TableCharts
com.sun.star.container.XEnumerationAccess|INTERFACE||com.sun.star.table.TableCharts
Here the interfaces explored via reflection:
xTableCharts-interfaces (via reflection):
com.sun.star.table.XTableCharts
com.sun.star.container.XIndexAccess
com.sun.star.container.XEnumerationAccess
