All Implemented Interfaces:

MacroExpander<QueryTargetsAndOutputsMacro,QueryMacroExpander.QueryResults>

public class QueryTargetsAndOutputsMacroExpander
extends QueryMacroExpander<QueryTargetsAndOutputsMacro>

Used to expand the macro $(query_targets_and_outputs "some(query(:expression))") to the full target names and the set of the outputs of the targets matching the query separated by a space. Example queries

   '$(query_targets_and_outputs "deps(:foo)")'
   '$(query_targets_and_outputs "filter(bar, classpath(:bar))")'
   '$(query_targets_and_outputs "attrfilter(annotation_processors, com.foo.Processor, deps(:app))")'
 

Example output:

 $(query_targets_and_outputs "deps(:foo)") ->
   "//:bar1 /tmp/project/buck-out/gen/bar1/out_file //:bar2 /tmp/project/buck-out/gen/bar2/out_file"
