  • trait DestructureTypes extends AnyRef

    A generic means of breaking down types into their subcomponents.

    A generic means of breaking down types into their subcomponents. Types are decomposed top down, and recognizable substructure is dispatched via self-apparently named methods. Those methods can be overridden for custom behavior, but only the abstract methods require implementations, each of which must create some unknown "Node" type from its inputs.

    • wrapProduct create Node from a product of Nodes
    • wrapSequence create Node from a sequence of Nodes
    • wrapAtom create Node from an arbitrary value

    This is a work in progress.

    This imposes additional structure beyond that which is visible in the case class hierarchy.

    This imposes additional structure beyond that which is visible in the case class hierarchy. In particular, (too) many different constructs are encoded in TypeRefs; here they are partitioned somewhat before being dispatched.

    For example, a typical type parameter is encoded as TypeRef(NoPrefix, sym, Nil) with its upper and lower bounds stored in the info of the symbol. Viewing the TypeRef naively we are treated to both too much information (useless prefix, usually empty args) and too little (bounds hidden behind indirection.) So drop the prefix and promote the bounds.
