-------------------------------------
Labels: beginner (was: )
> Remove argType parameter from FNZeroArgExpr and derived classes
> ---------------------------------------------------------------

> Key: DAFFODIL-2331

> Project: Daffodil
> Issue Type: Improvement
> Components: Clean Ups
> Reporter: John Interrante
> Priority: Minor
> Labels: beginner
>
> Expression.scala uses FNZeroArgExpr to implement fn:local-name,
> fn:namespace-uri, dfdlx:outputTypeCalcNextSibling, dfdlx:repTypeValue, and
> dfdlx:logicalTypeValue functions. It has to pass NodeInfo.XXX for the
> argType parameter, even though the argType parameter shouldn't be needed if
> there are zero arguments. Should we remove this parameter? It looks like
> argType is used only in targetTypeForSubexpression, which should never be
> called in FNZeroArgExpr since there are zero arguments.
> If we remove the argType parameter, we also shouldn't need to pass argType to
> the constructor for FNNamespaceURI0 and similar classes in FNFunctions.scala.
> People who can answer questions about this issue are Steve Lawrence and
> myself (although Steve can answer questions better).
