[jira] [Created] (FLINK-24251) Make default constructor of BinaryStringData private

Caizhi Weng created FLINK-24251:
-----------------------------------

             Summary: Make default constructor of BinaryStringData private
                 Key: FLINK-24251
                 URL: https://issues.apache.org/jira/browse/FLINK-24251
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / Runtime
            Reporter: Caizhi Weng


In FLINK-23289 we add a not null checking for {{BinarySection}}. After the change the default constructor of {{BinaryStringData}} will now construct a {{BinaryStringData}} with {{null}} Java object and {{null}} {{BinarySection}}. This is different from the behavior before where the default constructor constructs an empty binary string.

Although {{BinaryStringData}} is an internal class, it might confuse some developers (actually I myself have been confused) if they build their programs around this class. So we should make the default constructor construct an empty binary string again without breaking the not null checking.
