--------------------------------------
Summary: Make RexLiteral member fields accessible by sub-class
Key: CALCITE-3483
URL: https://issues.apache.org/jira/browse/CALCITE-3483
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Haisheng Yuan
RexLiteral may be sub-classed and some methods may be overrode. e.g.
{{printAsJava}}. But currently, RexLiteral fields are private, sub-classes
can't access these fields, which makes methods like {{printAsJava}} unable to
be overrode. We recommend make RexLiteral member fields protected, so that we
can sub-class it, and customize the behavior of methods such as
{{printAsJava}}. Does it make sense?
