case class ExtractorTreeMaker(extractor: Global.Tree, extraCond: Option[Global.Tree], nextBinder: Global.Symbol)(subPatBinders: List[Global.Symbol], subPatRefs: List[Global.Tree], potentiallyMutableBinders: Set[Global.Symbol], extractorReturnsBoolean: Boolean, checkedLength: Option[Int], prevBinder: Global.Symbol, ignoredSubPatBinders: Set[Global.Symbol]) extends FunTreeMaker with PreserveSubPatBinders with Product with Serializable
Make a TreeMaker that will result in an extractor call specified by extractor
the next TreeMaker (here, we don't know which it'll be) is chained after this one by flatMap'ing
a function with binder nextBinder
over our extractor's result
the function's body is determined by the next TreeMaker
(furthermore, the interpretation of flatMap
depends on the codegen instance we're using).
The values for the subpatterns, as computed by the extractor call in extractor
,
are stored in local variables that re-use the symbols in subPatBinders
.
This makes extractor patterns more debuggable (scala/bug#5739).

The substitution that specifies the trees that compute the values of the subpattern binders.
The substitution that specifies the trees that compute the values of the subpattern binders.
We pretend to replace the subpattern binders by subpattern refs (Even though we don't do so anymore -- see scala/bug#5158, scala/bug#5739 and scala/bug#6070.)
