------------------------------------------

             Summary: makeLiteral(Arrays.asList(...), structType, allowCast=any) does not work for Enumerable
                 Key: CALCITE-1976
                 URL: https://issues.apache.org/jira/browse/CALCITE-1976
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.13.0
            Reporter: Vladimir Sitnikov
            Assignee: Julian Hyde


org.apache.calcite.adapter.enumerable.RexToLixTranslator#translateLiteral creates ConstantExpression with {{List}} contents, and  org.apache.calcite.linq4j.tree.ConstantExpression#write just misses a case for List/Map, thus it resorts to plain {{toString}} and produces the following code:

{code:java}
            public Object current() {
              final org.eclipse.mat.snapshot.model.IObject v0 = com.github.vlsi.mat.calcite.functions.ISnapshotMethods.getIObject(com.github.vlsi.mat.calcite.SnapshotHo
              return new Object[] {
                  com.github.vlsi.mat.calcite.functions.ISnapshotMethods.toReference(v0),
                  [0, 1], <-- does not compile
                  org.apache.calcite.runtime.SqlFunctions.toFloat(com.github.vlsi.mat.calcite.functions.IObjectMethods.resolveSimpleValue(v0, "loadFactor")),
...
{code}
