FlattenProjections

class FlattenProjections extends Phase

Flatten all Pure node contents into a single StructNode.

After this phase, all Pure nodes produce a StructNode of primitive fields. As a side-effect, nested NominalTypes are eliminated.

    Flatten a projection into a StructNode.

    Flatten a projection into a StructNode.

    collapse

    If set to true, duplicate definitions are combined into a single one. This must not be used in the top-level Bind because the definitions have to match the top-level type (which is used later in createResultSetMapping). Any duplicates there will be eliminated in hoistClientOps. It is also disabled directly under a Union because the columns on both sides have to match up.

  6. def splitPath(n: PathElement, candidates: Set[TypeSymbol]): Option[(PathElement, List[TermSymbol], TypeSymbol)]

    Split a path into the shortest part with a NominalType and the rest on top of it.

    Split a path into the shortest part with a NominalType and the rest on top of it. Returns None if there is no NominalType with one of the candidate TypeSymbols in the path, otherwise returns Some(base, rest, tsym) where tsym is the symbol that was found and base is the Node in the path which has a NominalType of that symbol. rest is a (possibly empty) path of symbols on top of base.
