the values.child() call would also do a bounds check,
but only to rise a error::Invalid "index out of bounds".
So now we generate a clear message to indicate that
actually a runtime-checked type mismatch caused this problem
still TODO: the ability to use immutable types
within the command framework. In theory, this
shouldn't be had to implement, since we're creating
a new opaque value holder within the command registry
anyway, so it should be sufficient to refrain from
re-assigning a new value tuple. This is relevant,
since e.g. our time framework is built on immutable
value types.
...when the Test-Nexus processes a command binding message.
In the real system of course we do not want to log every bind message.
The challenge here is the fact that command binding as such
is opaque, and the types of the data within the bind message
are opaque as well. Finally I settled on the compromise
to log them as strings, but only the DataCap part;
most value types applicable within GenNode
have a string representation to match.
based on the new generic tuple builder, we're now able to
add a new binding function into the command implementation
machinery, alongside the existing one. As it stands, the
latter will be used rather by unit tests, while the new
access path is what will be actually taken within
the application, when receiving argument binding
messages dispatched via the UI-Bus.
based on the previous experiments, this adds a fake operation
and a definition frame to hook this operation as pseudo Proc-Layer command
WIP: the invocation itself is not yet implemented.
We need to build a custom invocation pattern for that,
in order to be able to capture the instance-ID of the command
on invocation
NOTE: also, because of #989, we can not bind a time value for this test
basically this comes down to provide some convenience fixture
within the test::Nexus, which automatically generates and wires
mock commands.
Not sure if this is even possible to the extent envisioned here
- remove unnecessary includes
- expunge all remaining usages of boost::format
- able to leave out the expliti string(elm) in output
- drop various operator<<, since we're now picking up
custom string conversions automatically
- delete diagnostics headers, which are now largely superfluous
- use newer helper functions occasionally
I didn't blindly change any usage of <iostream> though;
sometimes, just using the output streams right away
seems adequate.
this test is intended as counterpart to
AbstractTangible_test::verify_mockManipulation()
It creates a mock element and verifies bidirectional
connnectivity to the UI-Bus
