Detailed Description

A single-row write operation to be sent to a Kudu table.

This is the abstract base class from which the particular row operations (KuduInsert, KuduUpdate, etc) are derived. These subclasses are instantiated by KuduTable::NewInsert(), etc.

The row key, as well as the columns to be inserted or updated are set using the embedded KuduPartialRow object accessible via mutable_row().

Typical usage example:

KuduInsert* t = table->NewInsert();
KUDU_CHECK_OK(t->mutable_row()->SetInt32("key", 1234));
KUDU_CHECK_OK(t->mutable_row()->SetStringCopy("foo", "bar"));
KUDU_CHECK_OK(session->Apply(t));

Member Function Documentation

mutable_row()

KuduPartialRow * kudu::client::KuduWriteOperation::mutable_row ( )

inline

Note

To work with a row, use the KuduPartialRow API for field setters, etc.

Returns

Pointer to the corresponding row-like object.

row()

const KuduPartialRow & kudu::client::KuduWriteOperation::row ( ) const

inline

Note

To work with a row, use the KuduPartialRow API for field getters, etc.

Returns

Immutable reference to the corresponding row-like object.

table()

const KuduTable * kudu::client::KuduWriteOperation::table ( ) const

inline

Returns

Raw pointer to KuduTable object representing the table that the write is targeted for.

ToString()

virtual std::string kudu::client::KuduWriteOperation::ToString ( ) const

pure virtual

Returns

String representation of the operation.

Implemented in kudu::client::KuduInsert, kudu::client::KuduInsertIgnore, kudu::client::KuduUpsert, kudu::client::KuduUpsertIgnore, kudu::client::KuduUpdate, kudu::client::KuduUpdateIgnore, kudu::client::KuduDelete, and kudu::client::KuduDeleteIgnore.
