Examples of org.eigenbase.rex.RexNode.accept()

org.eigenbase.rex.RexNode.accept()
Accepts a visitor, dispatching to the right overloaded {@link RexVisitor#visitInputRef visitXxx} method.
Also see {@link RexProgram#apply(RexVisitor,java.util.List,RexNode)}, which applies a visitor to several expressions simultaneously.

          final RexNode left = call.getOperands().get(0);
          final RexLiteral literal = (RexLiteral) call.getOperands().get(1);
          final String field = (String) literal.getValue2();
//          buf.append('\'');
          final int length = buf.length();
          left.accept(this);
          if (buf.length() > length) {
            // check before generating empty LHS if inputName is null
            buf.append('.');
          }
          buf.append(field);
