against
- the Quantifier EnumeratedAttribute to use.
-
setWhen
Set the comparison to be used. Default "equal".- Parameters:
when
- the Comparison EnumeratedAttribute to use.
-
createControl
Create the nested control element. These are the resources to compare against.- Returns:
- ResourceCollection.
-
isSelected
Return true if this Resource is selected.- Specified by:
isSelected
in interfaceResourceSelector
- Parameters:
r
- the Resource to check.- Returns:
- whether the Resource was selected.
-
