    Cleans the flag set of the given modifiers.

    Cleans the flag set of the given modifiers.

    The type-checking process annotates definitions with various flags. Some of them can also be inserted by user-code or even have a corresponding Scala language construct, but others are only used by the type-checker. Certain flags can interfere with type-checking and cause it to fail. Those flags can be safely removed and will be re-inserted during type-checking when needed.

    This method eliminates some problematic cases.

    Creates an AST representing the given type.

    Creates an AST representing the given type.

    The type-checking process creates synthetic type trees and it is possible to insert trees with type information, but it is not easily possible to create an AST for a given type.

    This method attempts to create such an AST, which is persistent across type-checking and un-type-checking.

    Re-type-checks the given tree, i.e., first un-type-checks it and then type-checks it again using untypecheck and typecheck, respectively.

    Re-type-checks the given tree resetting all symbols using the org.scalamacros.resetallattrs library, i.e., first un-type-checks it and then type-checks it again using untypecheckAll and typecheck, respectively.

  22. def typecheck(tree: scala.reflect.macros.Universe.Tree): scala.reflect.macros.Universe.Tree

    Permalink

    Type-checks the given tree.

    Type-checks the given tree. If type-checking fails, aborts the macro expansion issuing the type-checking error.

    The type-checking process distorts certain ASTs (such as representations of extractors, lazy values or case classes) in a way that they cannot be type-checked again. The issue is described in SI-5464.

    Permalink

    Un-type-checks the given tree.

    Un-type-checks the given tree.

    The type-checking process distorts certain ASTs (such as representations of extractors, lazy values or case classes) in a way that they cannot be type-checked again. The issue is described in SI-5464.

    This method tries to restore the AST to a form, which can be type-checked again.
