Haisheng Yuan updated CALCITE-3483:
-----------------------------------
Description: 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}}
meaningless 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? (was: 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?)
