[jira] [Created] (ORC-999) [C++] Add PredicateDataType in PredicateLeaf::toString() and Literal::toString()

Quanlong Huang created ORC-999:
----------------------------------

             Summary: [C++] Add PredicateDataType in PredicateLeaf::toString() and Literal::toString()
                 Key: ORC-999
                 URL: https://issues.apache.org/jira/browse/ORC-999
             Project: ORC
          Issue Type: Improvement
          Components: C++
    Affects Versions: 1.7.0
            Reporter: Quanlong Huang
            Assignee: Quanlong Huang


Currently, the output of PredicateLeaf::toString() looks like
{code}
leaf-0 = (column(id=7) <= 132842), expr = (not leaf-0)
{code}
While debugging an issue, I realize that PredicateDataType of PredicateLeaf and Literal can be different (due to a mistake). It'd be helpful if we show the data type in toString() outputs, or introducing a toDebugString() method to provide more detailed info.
