类 LegacyTimestampTypeInfo

java.lang.Object

org.apache.flink.api.common.typeinfo.TypeInformation<T>

org.apache.flink.api.common.typeinfo.SqlTimeTypeInfo<Timestamp>

org.apache.flink.table.runtime.typeutils.LegacyTimestampTypeInfo

所有已实现的接口:

Serializable, org.apache.flink.api.common.typeinfo.AtomicType<Timestamp>

public class LegacyTimestampTypeInfo
extends org.apache.flink.api.common.typeinfo.SqlTimeTypeInfo<Timestamp>

TypeInformation for Timestamp.

The difference between Types.SQL_TIMESTAMP is this TypeInformation holds a precision Reminder: Conversion from DateType to TypeInformation (and back) exists in TableSourceUtil.computeIndexMapping, which should be fixed after we remove Legacy TypeInformation TODO: https://issues.apache.org/jira/browse/FLINK-14927
