Method Summary

Modifier and Type	Method and Description
static Optional<DataType>	fromClassToDataType(Class<?> clazz)
static LogicalType	fromDataToLogicalType(DataType dataType)
static LogicalType[]	fromDataToLogicalType(DataType[] dataTypes)
static org.apache.flink.api.common.typeinfo.TypeInformation<?>	fromDataTypeToLegacyInfo(DataType dataType) Deprecated. Please don't use this method anymore. It will be removed soon and we should not make the removal more painful. Sources and sinks should use the method available in context to convert, within the planner you should use either InternalTypeInfo or ExternalTypeInfo depending on the use case.

It will be removed soon and we should not make the removal more painful. Sources and sinks should use the method available in context to convert, within the planner you should use either InternalTypeInfo or ExternalTypeInfo depending on the use case.
static DataType	fromLegacyInfoToDataType(org.apache.flink.api.common.typeinfo.TypeInformation<?> typeInfo) Deprecated. Please don't use this method anymore. It will be removed soon and we should not make the removal more painful.
