Hello,
I am dealing with the following problem. A REST resource returns an
(DTO) object called statistics (of type Statistics) holding various
properties. With string template, each property can be inserted into
an XML file, like
<A>$statistics.propertyA$</A>
where the corresponding method on the Statistics object is
getPropertyA().
One of the properties requires an argument of type String, where the
actual method signature is getNumberFor(String name). It returns an
int. The name is obtained from a list of names obtained from the
statistics objects as well. The idea is to iterate through the list of
names and return a number (int) for each name.
Thus, the XML code that I try to complete looks like:
<socials>
$statistics.names: { name |
<social>
<name>$name$</name>
<number>$statistics.numberFor(name)$</tribc:number>
</social>
}$
</socials>
The Statistics object holds among other things a Map<String, Integer>
with the requested numbers.
The line $statistics.numberFor(name)$ is however erroneous. I cannot
pass the current value of name to the method in question.
My question is now: How to pass a argument to a given method on an
object using string template. The string template website did not give
a clear answer, so maybe it is not even possible, or maybe I just
completely overlooked it.
Any help is appreciated.
Hi André.
I am not an ST expert at all, but I really think there is no support for
generic method invocation on ST expressions: the only methods supported
seem to ne related to properties, "à la JavaBean".
Yeah, that's what I thought.
For your use case, I'd change a bit the application logic by providing a
C3 REST controller that would act as a "data conversion proxy" between
the sitemap and the actual REST resource you are currently dealing with.
In this way you could query the external REST resource from the C3 REST
controller body and prepare the data in a format that's suitable for ST.
OK, I'll have a look at this. Alternatively, I may simply add a method
to the DTO that returns an XML representation of the DTO. With ST, one
would use then $statistics.asXml$ or something, but it appears that all
> and < symbols are replaced with < and > which is not what I
want of course.
Thanks,
Andre
