Detailed Description

Representation of the column schema.

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.

kudu::client::KuduColumnSchema::KuduColumnSchema ( const KuduColumnSchema & other )

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 )

Make this object an identical copy of the other one.

Parameters

[in] other The reference object to copy from.

static std::string kudu::client::KuduColumnSchema::DataTypeToString ( DataType type )

static

Parameters

[in] type Column data type.

Returns: String representation of the column data type.

bool kudu::client::KuduColumnSchema::Equals ( const KuduColumnSchema & other ) const

Check whether the object is identical to the other one.

Parameters

[in] other The reference object to compare with.

Returns: true iff the object is identical to the specified one.

bool kudu::client::KuduColumnSchema::is_nullable ( ) const

Returns: true iff the column schema has the nullable attribute set.

KuduColumnSchema& kudu::client::KuduColumnSchema::operator= ( const KuduColumnSchema & other )

The assignment operator.

Parameters

[in] other The reference object to assign from.

Returns: The updated object.

DataType kudu::client::KuduColumnSchema::type ( ) const

Returns: Type of the column schema.
