Member Enumeration Documentation

enum kudu::client::KuduColumnSchema::DataType

Supported data types for columns.

Enumerator:

TIMESTAMP

deprecated, use UNIXTIME_MICROS

Constructor & Destructor Documentation

kudu::client::KuduColumnSchema::KuduColumnSchema	(	const std::string &	name,
		DataType	type,
		bool	is_nullable = false,
		const void *	default_value = NULL,
		KuduColumnStorageAttributes	attributes = KuduColumnStorageAttributes()
	)

Deprecated:

Use KuduSchemaBuilder instead.

Todo:

KUDU-809: make this hard-to-use constructor private. Clients should use the Builder API. Currently only the Python API uses this old API.

Parameters:

[in]	name	The name of the column.
[in]	type	The type of the column.
[in]	is_nullable	Whether the column is nullable.
[in]	default_value	Default value for the column.
[in]	attributes	Column storage attributes.

)

Construct KuduColumnSchema object as a copy of another object.

Parameters:

[in]

other

The reference object to copy from.

Member Function Documentation

void kudu::client::KuduColumnSchema::CopyFrom

(

const KuduColumnSchema &

other

)

Parameters:

[in]

other

The reference object to copy from.

static std::string kudu::client::KuduColumnSchema::DataTypeToString

(

DataType

type

)

[static]
