Member Function Documentation

isPasswordNeeded()

bool KDbConnectionData::isPasswordNeeded

(

)

const

Returns

true if password is needed for performing connection. The password has to be provided by the user.

Note

This method needs information about driver ID; it returns false if driverId() does not return a valid ID.

<

Todo

temp.: change this if there are file-based drivers requiring a password

Definition at line 52 of file KDbConnectionData.cpp.

toUserVisibleString()

QString KDbConnectionData::toUserVisibleString

(

UserVisibleStringOptions

options = UserVisibleStringOption::AddUser

)

const

Returns

A user-visible string for the connection data driverId() is used to know if driver handles server connections. If it's not possible to check the driver, defaults to "file" connection.

Example strings:

• "myhost.org:12345" if a host and port is specified;
• "localhost:12345" if only a port and server-based driver is specified;
• "user@myhost.org:12345" if user is specified too
• "<file>" if a file-based driver is specified but no filename in the databaseName attribute
• "file: pathto/mydb.kexi" if a file-based driver is specified and filename is specified in the databaseName attribute
• "<file>" if the driver is unknown or not specified and no databaseName is specified

User name is added if (options & UserVisibleStringOption::AddUser) is true (the default).

Member Data Documentation

caption

QString KDbConnectionData::caption

@getter

Returns

caption of the connection Captions are optional for identyfying given connection by name eg. for users. @setter Sets caption of the connection

Definition at line 64 of file KDbConnectionData.shared.h.

databaseName

QString KDbConnectionData::databaseName

@getter

Returns

database name

Optional attribute explicitly providing database name. If not empty, the database driver will attempt to use the database (e.g. with "USE DATABASE" SQL statement).

For file-based database engines like SQLite, the database name is equal to filename (absolute or relative) that should be open. In this case hostName and port is unused.

Can be empty, in which case if database name is required by the connection, after connecting KDbConnection::useDatabase() should be called. @setter Explicitly sets database name.

Definition at line 55 of file KDbConnectionData.shared.h.

description

QString KDbConnectionData::description

@getter

Returns

additional description for the connection @setter Sets additional description for the connection

Definition at line 72 of file KDbConnectionData.shared.h.

driverId

QString KDbConnectionData::driverId

@getter

Returns

identifier of the driver. ID (unique, not i18n-ed) of driver that is used (or should be used) to create a connection. If you pass this KDbConnectionData object to KDbDriver::createConnection() to create connection, the driverId member will be updated with a valid KDb driver ID. In other situations the driverId member may be used to store information what driver should be used to perform connection, before we get an appropriate driver object from KDbDriverManager. @setter Sets identifier of the driver to use

Definition at line 87 of file KDbConnectionData.shared.h.

hostName

QString KDbConnectionData::hostName

@getter

Returns

host name used for creating remote connections Can be IP number. Can be empty if the connection is not remote. If empty, "localhost" is used. @setter Sets host name used for creating remote connections

Definition at line 106 of file KDbConnectionData.shared.h.

localSocketFileName

QString KDbConnectionData::localSocketFileName

@getter

Returns

name of local (named) socket file.

For local connections only. If empty, it's driver will try to locate existing local socket file. Empty by default. @setter Sets name of local (named) socket file

Definition at line 140 of file KDbConnectionData.shared.h.

password

QString KDbConnectionData::password

@getter

Returns

password used for creating connections

Can be empty string (QString("")) or null (QString()). If it is empty, empty password is passed to the connection. If it is null, no password is saved and thereform no password is passed to the connection. In the latter case, applications that KDb should ask for the password before performing connection if password is required by the connection. @setter Sets password used for creating connections

Definition at line 153 of file KDbConnectionData.shared.h.

port

int KDbConnectionData::port

@getter port used for creating remote connections The default is 0, what means using the database engine's default port. @setter Sets port used for creating remote connections

Definition at line 114 of file KDbConnectionData.shared.h.

savePassword

bool KDbConnectionData::savePassword

@getter

Returns

true if the connection's password should be stored in a configuration file for later use. False by default, in most cases can be set to true when non-null password is known. For instance, this flag can be then shown for a user as a checkbox in the graphical interface. @setter Sets password-saving flag used to decide if the connection's password should be stored in a configuration file for later use

Definition at line 164 of file KDbConnectionData.shared.h.

useLocalSocketFile

bool KDbConnectionData::useLocalSocketFile

@getter

Returns

true if local socket file should be used instead of TCP/IP port.

Only meaningful for connections with localhost as server. True by default, so local communication can be optimized, and users can avoid problems with TCP/IP connections disabled by firewalls.

If true, hostName and port will be ignored and localSocketFileName() will be used. On MS Windows this option is usually ignored and TCP/IP connection to the localhost is performed. @setter Sets flag for usage of local socket file.

userName

QString KDbConnectionData::userName

@getter

Returns

username used for creating connections Can be empty. @setter Sets username used for creating connections
