## Constructor & Destructor Documentation

virtual Gnome::Gda::Config::~Config | ( | ) | `[virtual]`

Gnome::Gda::Config::Config | ( | ) | `[protected]`

## Member Function Documentation

static bool Gnome::Gda::Config::can_modify_system_config | ( | ) | `[static]`

Tells if the global (system) configuration can be modified (considering system permissions and settings)

Returns:
  `true` if system-wide configuration can be modified.

static bool Gnome::Gda::Config::dsn_needs_authentication | ( | const Glib::ustring & | dsn_name ) | `[static]`

Tells if the data source identified as dsn_name needs any authentication.

If a <username> and optionally a <password> are specified, they are ignored.

Parameters:

  dsn_name | The name of a DSN, in the "[<username>[:<password>]@]<DSN>" format.

Returns:
  `true` if an authentication is needed.

static Glib::RefPtr<Config> Gnome::Gda::Config::get | ( | ) | `[static]`

Get a pointer to the global GdaConfig object.

Returns:
  A non `0` pointer to a Gda::Config.

static GdaDsnInfo* Gnome::Gda::Config::get_dsn_info | ( | const Glib::ustring & | dsn_name ) | `[static]`

Get information about the DSN named dsn_name.

dsn_name's format is "[<username>[:<password>]@]<DSN>" (if <username> and optionally <password> are provided, they are ignored). Also see the gda_dsn_split() utility function.

Parameters:

  dsn_name | The name of the DSN to look for.

Returns:
  A pointer to read-only Gda::DsnInfo structure, or `0` if not found.

static int Gnome::Gda::Config::get_nb_dsn | ( | ) | `[static]`

Get the number of defined DSN.

Returns:
  The number of defined DSN.

static Glib::RefPtr<ServerProvider> Gnome::Gda::Config::get_provider | ( | const Glib::ustring & | provider_name ) | `[static]`

Get a pointer to the session-wide Gda::ServerProvider for the provider named provider_name.

The caller must not call Glib::object_unref() on the returned object.

This method may fail with a Gda::CONFIG_ERROR domain error (see the Gda::ConfigError error codes).

Parameters:

  provider_name | A database provider.

Returns:
  A pointer to the Gda::ServerProvider, or `0` if an error occurred.

const GdaConfig* Gnome::Gda::Config::gobj | ( | ) | const`[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::ObjectBase.

GdaConfig* Gnome::Gda::Config::gobj | ( | ) | `[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::ObjectBase.

GdaConfig* Gnome::Gda::Config::gobj_copy | ( | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

static Glib::RefPtr<DataModel> Gnome::Gda::Config::list_dsn | ( | ) | `[static]`

Get a Gda::DataModel representing all the configured DSN, and keeping itself up to date with the changes in the declared DSN.

The returned data model is composed of the following columns: <itemizedlist> <listitem>

DSN name

</listitem> <listitem>

Provider name

</listitem> <listitem>

Description

</listitem> <listitem>

Connection string

</listitem> <listitem>

Username if it exists

static Glib::RefPtr<DataModel> Gnome::Gda::Config::list_providers | ( | ) | `[static]`

Get a Gda::DataModel representing all the installed database providers.

The returned data model is composed of the following columns: <itemizedlist> <listitem>

Provider name

</listitem> <listitem>

Description

</listitem> <listitem>

DSN parameters

</listitem> <listitem>

Authentication parameters

</listitem> <listitem>

File name of the plugin

</listitem> </itemizedlist>

Returns:
  A new Gda::DataModel.

Glib::PropertyProxy<Glib::ustring> Gnome::Gda::Config::property_system_filename | ( | ) |

File to use for system-wide DSN list.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly<Glib::ustring> Gnome::Gda::Config::property_system_filename | ( | ) | const

File to use for system-wide DSN list.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly<Glib::ustring> Gnome::Gda::Config::property_user_filename | ( | ) | const

File to use for per-user DSN list.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy<Glib::ustring> Gnome::Gda::Config::property_user_filename | ( | ) |

File to use for per-user DSN list.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
