Abstract Value Members

  1. abstract def arity: Int

    Return the arity of product types, should probably only be used implicitly The use case here is to see how many fake field names we need in Cascading to hold an intermediate value for mapReduceMap

    assert that the arity of this setter matches the fields given.

    assert that the arity of this setter matches the fields given. if arity == -1, we can't check, and if Fields is not a definite size, (such as Fields.ALL), we also cannot check, so this should only be considered a weak check.
