protected Expression |
makeCurriedFunction(int offset,
StructuredQName name,
Expression[] args,
IntSet placeMarkers)

Parse a function argument. |
ItemType |
parseFunctionItemType()
Parse the item type used for function items (XQuery 3.0 higher order functions) Syntax (changed by WG decision on 2009-09-22): function '(' '*' ') | function '(' (SeqType (',' SeqType)*)? ')' 'as' SeqType The "function(" has already been read |
