RexBuilder.makeRangeReference介绍

[英]Creates a reference to all the fields in the row. That is, the whole row as a single record object.
[中]创建对行中所有字段的引用。也就是说，将整行作为单个记录对象。

/**
 * Creates an expression with which to reference the expression whose
 * offset in its from-list is {@code offset}.

 return rexBuilder.makeRangeReference(
   pair.left.getRowType(),
   pair.right,
   false);
