Открытые методы

Метод	Описание
BeginTransaction ( ) : CqlBatchTransaction	Begins the transaction.
BeginTransaction ( IsolationLevel isolationLevel ) : CqlBatchTransaction	Begins the transaction.
Cancel ( ) : void	Cancels any ongoing open operation.
ChangeDatabase ( string databaseName ) : void	Changes the current database for an open connection.
Close ( ) : void	Closes the connection to the database. This is the preferred method of closing any open connection.
CqlConnection ( CqlConnectionStringBuilder config ) : System	Initializes a new instance of the CqlConnection class.
CqlConnection ( string connectionString ) : System	Initializes a new instance of the CqlConnection class.
CreateCqlCommand ( ) : CqlCommand	Creates and returns a T:CqlSharp.CqlCommand object associated with the current connection.
Open ( ) : void	Opens a database connection with the settings specified by the .
OpenAsync ( CancellationToken cancellationToken ) : Task	This is the asynchronous version of M:System.Data.Common.DbConnection.Open. The cancellation token can optionally be honored.The default implementation invokes the synchronous call and returns a completed task. The default implementation will return a cancelled task if passed an already cancelled cancellationToken. Exceptions thrown by Open will be communicated via the returned Task Exception property.Do not invoke other methods and properties of the DbConnection object until the returned Task is complete.
OpenInternal ( ) : void	Opens the connection with full cancellation support.
SetConnectionTimeout ( int timeout ) : void	Sets the connection timeout.
Shutdown ( string connectionString ) : void	Shutdowns all interaction with the cluster as specified by the connection string. This will close all open connection, and thereby fail all ongoing cql operations.
ShutdownAll ( ) : void	Shutdowns all interactions with all known clusters This will close all open connection, and thereby fail all ongoing cql operations.

Метод	Описание
CompleteOpen ( Logger logger ) : void
CqlConnection ( ) : System	Initializes the CqlConnection class.
GetConnection ( PartitionKey partitionKey = default(PartitionKey) ) : Connection	Requests a connection to be used for a command. Will reuse connection level connection if available

Begins the transaction.

public BeginTransaction ( ) : CqlBatchTransaction
Результат	CqlBatchTransaction

BeginTransaction() публичный Метод

Begins the transaction.

public BeginTransaction ( IsolationLevel isolationLevel ) : CqlBatchTransaction
isolationLevel	IsolationLevel	The isolation level.

ChangeDatabase() публичный Метод

Changes the current database for an open connection.

/// CqlConnection must be open before Database can be changed. /// or /// Changing a database is only supported with a ConnectionStrategy that offers exclusive connections ///

public ChangeDatabase ( string databaseName ) : void
databaseName	string	Specifies the name of the database for the connection to use.
Результат	void

Close() публичный Метод

Closes the connection to the database. This is the preferred method of closing any open connection.

public Close ( ) : void

CqlConnection() публичный Метод

Initializes a new instance of the CqlConnection class.

public CqlConnection ( CqlConnectionStringBuilder config ) : System
config	CqlConnectionStringBuilder	The config.
Результат	System

public CreateCqlCommand ( ) : CqlCommand
Результат	CqlCommand

CreateDbCommand() защищенный Метод

Creates and returns a T:System.Data.Common.DbCommand object associated with the current connection.

protected CreateDbCommand ( ) : DbCommand
Результат	DbCommand

Open() публичный Метод

Opens a database connection with the settings specified by the .

public Open ( ) : void
Результат	void

OpenAsync() публичный Метод

This is the asynchronous version of M:System.Data.Common.DbConnection.Open. The cancellation token can optionally be honored.The default implementation invokes the synchronous call and returns a completed task. The default implementation will return a cancelled task if passed an already cancelled cancellationToken. Exceptions thrown by Open will be communicated via the returned Task Exception property.Do not invoke other methods and properties of the DbConnection object until the returned Task is complete.
