abstract class ImportExtractor extends AnyRef
An extractor class to create and pattern match with syntax Import(expr, selectors)
.
This AST node corresponds to the following Scala code:
import expr.{selectors}
Selectors are a list of ImportSelectors, which conceptually are pairs of names (from, to). The last (and maybe only name) may be a nme.WILDCARD. For instance:
import qual.{x, y => z, _}
Would be represented as:
Import(qual, List(("x", "x"), ("y", "z"), (WILDCARD, null)))
The symbol of an Import
is an import symbol @see Symbol.newImport.
It's used primarily as a marker to check that the import has been typechecked.
