| OrderedMap | | public class OrderedMap extends MethodProc implements CanInline,Inlineable(Code) | | A procedure used to represent a FLWOR expression with
an
order by clause.
(
gnu.kawa.functions.ValuesMap is used for FLWOR expression
that don't have an
order by clause.)
As returned by the parser:
for $x1 in exp1, $x2 in exp2 where cond order by comparator1 ... return body
is represented as
ordered-map(tuple-sequence, body-function,
comparator-function1, flags1, collation1, ...)
Here tuple-sequence is an expression that returns a sequence of tuples,
which are currently implemnted as Java Object[] arrays.
After inlining we get:
ordered-map(tuple-sequence.
OrderedTuples.make$V(body-function,
new Object[]{comparator-function1, flags1, collation1, ...}))
A future optimization would be to create an instance of a new sub-class
of OrderedTuples. Then the body-function and comparator-functions
could be compiled as methods to that class. That wins especially
if it saves us having to create extra frame classes.
