Hi everyone,
i have a questions on how to create a nested output strategy.
As an example following code from the LatLngToGeo Controller [1].
Here I created a simple output strategy:
.outputStrategy(OutputStrategies.append(EpProperties.stringEp(
Labels.from(
"point_wkt",
"wkt",
"wkt point from long lat values"),
WKT,
SO.Text))
)
I see there are some options for EpProperties methods like
.outputStrategy(OutputStrategies.append(EpProperties.listNestedEp(
or
.outputStrategy(OutputStrategies.append(EpProperties.nestedEp(
that seems to support nested values. What are the difference between the
different listNestedEP methods and nestedEP method and how should the output
strategy looks like in the end?
My goal is to have an output event something like an array with point WKT on
position 0 and EPSG Code value on the position 1 (created in this source [2]).
Thanks
Florian
