Abstract Value Members

  1. abstract def bind(in: InType, inputSchema: Seq[Attribute]): InType

    Binds an input expression to a given input schema

    Binds an input expression to a given input schema

    protected
  2. abstract def canonicalize(in: InType): InType

    Canonicalizes an input expression.

    Canonicalizes an input expression. Used to avoid double caching expressions that differ only cosmetically.

  3. abstract def create(in: InType): OutType

    Generates a class for a given input expression.

    Generates a class for a given input expression. Called when there is not cached code already available.
