Accessing properties from the Code Template Editor

[mrks]

Hi,

I want to read the property "Direction" of an assoziation between two classes from the Code Template Editor - there is no field substitution macro available to access it directly, so I tried %connectorTag:"Direction"%, %connectorSourceTag:"Direction"%, ... without success.

Any idea how to do this? (EA9.1.910)

Cheers,
mrks

At a guess, you're not in the connector template.

... I cannot find any connector templates in the code template editor - do you mean the templates in the transformation editor? I want to access the properties from the Linked Attribute Template.

I have tried adding a custom template of type Connector, but I still cannot access the properties I need.

Is there a difference between the available field substitution macros and the template I use? - Aren't these always the same?

Any help is welcome  8-)

The connector templates aren't used by default in the code generation tempates, but you can still add one in and use it. You will of course have to add a list over the connectors before it will be used.

Simon, I do not understand how to add a list over the connectors. I added a custom template of type connector, named "Assoziation" and placed it at the position where I want to use the connector property 'Direction'.

Code: [Select]

...
%if linkCard != ""%
$direction=%list="Connector__Assoziation" @separator="\n"%
@system.annotation.LinkDirection (
            direction="$direction"
)
%endIf%
...

the code above results in:

Code: [Select]

...
@system.annotation.LinkDirection (
            direction="connectorDirection=Source -> Destination
connectorDirection=Source -> Destination
connectorDirection=Bi-Directional
connectorDirection=Source -> Destination
connectorDirection=Source -> Destination
connectorDirection=Source -> Destination"
)
public java.util.Set<SessionStatus> sessionStatus;
...

where the "Connector__Assoziation" template is:

Code: [Select]

connectorDirection=%connectorDirection%

and the following is what I need:

Code: [Select]

...
@system.annotation.LinkDirection (
            direction="connectorDirection=Source -> Destination"
)
public java.util.Set<SessionStatus> sessionStatus;
...

What am I doing wrong?

a) You're listing over all connectors from the class.

Code: [Select]

%list="Connector__Assoziation" @indent="\t" @separator="\n" connectorGUID=linkGUID%
I also added an indent to match your expected indent.

b)Your connector template isn't coded to give what you want.

Code: [Select]

direction=%qt%connectorDirection=%connectorDirection%%qt%
Note, I have not executed this or touched the templates for some time so the specifics might need to be corrected.

Hi Simon, thanks a lot, that's it!  

I corrected the syntax to:

Code: [Select]

"%list="Connector__Assoziation" connectorGUID==linkGUID%"

... I do not even need the separator, there can always only be one link direction for each linked attribute.

cheers!
