### Type Members

1. #### type MacroContext = Analyzer.UnaffiliatedMacroContext { val universe: StdAttachments.this.global.type }

2. #### case class MacroExpanderAttachment(original: Global.Tree, desugared: Global.Tree) extends Product with Serializable

   Scratchpad for the macro expander, which is used to store all intermediate data except the details about the runtime.

3. #### case class MacroExpansionAttachment(expandee: Global.Tree, expanded: Any) extends Product with Serializable

   Is added by the macro engine to originals and results of macro expansions.

4. #### case class MacroRuntimeAttachment(delayed: Boolean, typerContext: Analyzer.Context, macroContext: Option[Analyzer.MacroContext]) extends Product with Serializable

5. #### case class SuperArgsAttachment(argss: List[List[Global.Tree]]) extends Product with Serializable

   After being synthesized by the parser, primary constructors aren't fully baked yet.

6. #### type UnaffiliatedMacroContext = Context

   Carries information necessary to expand the host tree.

   Carries information necessary to expand the host tree. At times we need to store this info, because macro expansion can be delayed until its targs are inferred. After a macro application has been successfully expanded, this attachment is destroyed.

5. #### final def ==(arg0: Any): Boolean

   Definition Classes
     AnyRef → Any

6. #### object DynamicRewriteAttachment extends Product with Serializable

   Since mkInvoke, the applyDynamic/selectDynamic/etc desugarer, is disconnected from typedNamedApply, the applyDynamicNamed argument rewriter, the latter doesn’t know whether it needs to apply the rewriting because the application has just been desugared or it needs to hold on because it’s already performed a desugaring on this tree.

7. #### object MacroImplRefAttachment extends Product with Serializable

8. #### object SuppressMacroExpansionAttachment extends Product with Serializable

   When present, suppresses macro expansion for the host.

19. #### final def getClass(): Class[_]

    Definition Classes
      AnyRef → Any

20. #### def hasMacroExpansionAttachment(any: Any): Boolean

    Determines whether the target is either an original or a result of a macro expansion.

    Determines whether the target is either an original or a result of a macro expansion. The parameter is of type `Any`, because macros can expand both into trees and into annotations.

21. #### def hasSuperArgs(tree: Global.Tree): Boolean

    Determines whether the given tree has an associated SuperArgsAttachment.

22. #### def hashCode(): Int

    Definition Classes
      AnyRef → Any

23. #### def isDynamicRewrite(tree: Global.Tree): Boolean

24. #### final def isInstanceOf[T0]: Boolean

    Definition Classes
      Any

25. #### def isMacroExpansionSuppressed(tree: Global.Tree): Boolean

    Determines whether a tree should not be expanded, because someone has put SuppressMacroExpansionAttachment on it or one of its children.

26. #### def isMacroImplRef(tree: Global.Tree): Boolean

    Determines whether a tree should or should not be adapted, because someone has put MacroImplRefAttachment on it.

27. #### def linkExpandeeAndDesugared(expandee: Global.Tree, desugared: Global.Tree): Unit

    After macro expansion is completed, links the expandee and the expansion result by annotating them both with a `MacroExpansionAttachment`.

28. #### def linkExpandeeAndExpanded(expandee: Global.Tree, expanded: Any): Unit

    After macro expansion is completed, links the expandee and the expansion result by annotating them both with a `MacroExpansionAttachment`.

    After macro expansion is completed, links the expandee and the expansion result by annotating them both with a `MacroExpansionAttachment`. The `expanded` parameter is of type `Any`, because macros can expand both into trees and into annotations.

29. #### def macroExpandee(tree: Global.Tree): Global.Tree

    Returns the original tree of the macro expansion if the argument is a macro expansion or EmptyTree otherwise.

30. #### def macroExpanderAttachment(tree: Global.Tree): Analyzer.MacroExpanderAttachment

    Loads underlying MacroExpanderAttachment from a macro expandee or returns a default value for that attachment.

31. #### def markDynamicRewrite(tree: Global.Tree): Global.Tree

32. #### def markMacroImplRef(tree: Global.Tree): Global.Tree

    Marks the tree as a macro impl reference, which is a naked reference to a method.

    Marks the tree as a macro impl reference, which is a naked reference to a method.

    This is necessary for typechecking macro impl references (see `DefaultMacroCompiler.defaultResolveMacroImpl`), because otherwise typing a naked reference will result in the "follow this method with `_' if you want to treat it as a partially applied function" errors.`

    This mark suppresses adapt except for when the annottee is a macro application.

33. #### final def ne(arg0: AnyRef): Boolean

    Definition Classes
      AnyRef

34. #### final def notify(): Unit

    Definition Classes
      AnyRef

35. #### final def notifyAll(): Unit

      AnyRef

36. #### def superArgs(tree: Global.Tree): Option[List[List[Global.Tree]]]

    Convenience method for `SuperArgsAttachment`.

    Convenience method for `SuperArgsAttachment`. Compared with `MacroRuntimeAttachment` this attachment has different a usage pattern, so it really benefits from a dedicated extractor.

37. #### def suppressMacroExpansion(tree: Global.Tree): Global.Tree

    Suppresses macro expansion of the tree by putting SuppressMacroExpansionAttachment on it.

38. #### final def synchronized[T0](arg0: ⇒ T0): T0

    Definition Classes
      AnyRef

39. #### def toString(): String

    Definition Classes
      AnyRef → Any

40. #### def unmarkDynamicRewrite(tree: Global.Tree): Global.Tree

41. #### def unmarkMacroImplRef(tree: Global.Tree): Global.Tree

    Unmarks the tree as a macro impl reference (see `markMacroImplRef` for more information).

    Unmarks the tree as a macro impl reference (see `markMacroImplRef` for more information).

    This is necessary when a tree that was previously deemed to be a macro impl reference, typechecks to be a macro application. Then we need to unmark it, expand it and try to treat its expansion as a macro impl reference.

42. #### def unsuppressMacroExpansion(tree: Global.Tree): Global.Tree

    Unsuppresses macro expansion of the tree by removing SuppressMacroExpansionAttachment from it and its children.
