Class DataType (1.0.3)

Indicated the type of data that can be stored in a structured data entity (e.g. a table).

If [type_code][google.cloud.automl.v1beta1.DataType.type_code] == ARRAY, then list_element_type is the type of the elements.

If [type_code][google.cloud.automl.v1beta1.DataType.type_code] == TIMESTAMP then time_format provides the format in which that time field is expressed. The time_format must either be one of: * UNIX_SECONDS * UNIX_MILLISECONDS * UNIX_MICROSECONDS * UNIX_NANOSECONDS (for respectively number of seconds, milliseconds, microseconds and nanoseconds since start of the Unix epoch); or be written in strftime syntax. If time_format is not set, then the default format as described on the type_code is used.

If true, this DataType can also be NULL. In .CSV files NULL value is expressed as an empty string.
