public class CqlConnection : DbConnection, ICloneable
The CqlConnection type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | CqlConnection |
Initializes a CqlConnection.
|
| CqlConnection(String) |
Initializes a CqlConnection.
|
Methods| Name | Description | |
|---|---|---|
| BeginTransaction | Starts a database transaction. (Inherited from DbConnection.) |
| BeginTransaction(IsolationLevel) | Starts a database transaction with the specified isolation level. (Inherited from DbConnection.) |
| ChangeDatabase | Changes the current database for an open connection. (Overrides DbConnectionChangeDatabase(String).) |
| Clone | |
| Close | Closes the connection to the database. This is the preferred method of closing any open connection. (Overrides DbConnectionClose.) |
| CreateCommand | Creates and returns a DbCommand object associated with the current connection. (Inherited from DbConnection.) |
| CreateObjRef | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.) |
| Dispose | Releases all resources used by the Component. (Inherited from Component.) |
| EnlistTransaction | Enlists in the specified transaction. (Inherited from DbConnection.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetLifetimeService | Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| GetSchema | Returns schema information for the data source of this DbConnection. (Inherited from DbConnection.) |
| GetSchema(String) | Returns schema information for the data source of this DbConnection using the specified string for the schema name. (Inherited from DbConnection.) |
| GetSchema(String, String) | Returns schema information for the data source of this DbConnection using the specified string for the schema name and the specified string array for the restriction values. (Inherited from DbConnection.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| InitializeLifetimeService | Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| Open | Opens a database connection with the settings specified by the ConnectionString. (Overrides DbConnectionOpen.) |
| OpenAsync | An asynchronous version of Open, which opens a database connection with the settings specified by the ConnectionString. This method invokes the virtual method OpenAsync(CancellationToken) with CancellationToken.None. (Inherited from DbConnection.) |
| OpenAsync(CancellationToken) | This is the asynchronous version of Open. Providers should override with an appropriate implementation. The cancellation token can optionally be honored.The default implementation invokes the synchronous Open 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. (Inherited from DbConnection.) |
| ToString | Returns a String containing the name of the Component, if any. This method should not be overridden. (Inherited from Component.) |
Properties| Name | Description | |
|---|---|---|
 | ConnectionString | Gets or sets the string used to open the connection. (Overrides DbConnectionConnectionString.) |
| ConnectionTimeout | Gets the time to wait while establishing a connection before terminating the attempt and generating an error. (Inherited from DbConnection.) |
| Container | Gets the IContainer that contains the Component. (Inherited from Component.) |
| Database |
Returns the Keyspace
(Overrides DbConnectionDatabase.) |
| DataSource | Gets the name of the database server to which to connect. (Overrides DbConnectionDataSource.) |
| ServerVersion | Gets a string that represents the version of the server to which the object is connected. (Overrides DbConnectionServerVersion.) |
| Site | Gets or sets the ISite of the Component. (Inherited from Component.) |
| State | Gets a string that describes the state of the connection. (Overrides DbConnectionState.) |
Events| Name | Description | |
|---|---|---|
 | Disposed | Occurs when the component is disposed by a call to the Dispose method. (Inherited from Component.) |
| StateChange | Occurs when the state of the event changes. (Inherited from DbConnection.) |
