Thanks Ross (with apologies if that isn’t the right name!)
I’m painfully aware that the scripting language isn’t Java and that it appears to be within the confines of a class definition of sub-dialect of Xtend.
I did try fully qualifying the two-argument Procedure (it’s not a Function as it doesn’t have a return value) and didn’t get any different results.
(Note that the $ syntax has changed since Xtend 2.4.1 according to both https://www.eclipse.org/xtend/documentation/203_xtend_expressions.html#xtend-expressions-literals and the corrections done by Designer)
import org.eclipse.xtext.xbase.lib.Procedures
import org.eclipse.xtext.xbase.lib.Procedures.Procedure2
val org.eclipse.xtext.xbase.lib.Procedures.Procedure2<GroupItem, LinkedHashMap<String, Number>> dimmer_group_set_to_preset = [ GroupItem dimmer_group, LinkedHashMap<String, Number> preset_map |
The Procedure2 import is flagged by Designer as unused.
Trying to define it as a Function (and adding a return value) has the same behavior
val Functions.Function2<GroupItem, LinkedHashMap<String, Number>, void> dimmer_group_set_to_preset = [ GroupItem dimmer_group, LinkedHashMap<String, Number> preset_map |
(Designer collapses the full path to Functions)
