Caizhi Weng updated FLINK-24251:
--------------------------------
Summary: Make default constructor of BinaryStringData construct empty
binary string again (was: Make default constructor of BinaryStringData private)
> Make default constructor of BinaryStringData construct empty binary string
> again
> --------------------------------------------------------------------------------
>
> Key: FLINK-24251
> URL: https://issues.apache.org/jira/browse/FLINK-24251
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Runtime
> Reporter: Caizhi Weng
> Priority: Minor
>
> 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.
