bool Gnome::Gda::SqlExpr::empty | ( |  | ) | const

static GType Gnome::Gda::SqlExpr::get_type | ( |  | ) |
| static

Get the GType for this class, for use with the underlying GObject type system.

GdaSqlExpr* Gnome::Gda::SqlExpr::gobj | ( |  | ) |
| inline

Provides access to the underlying C instance.

const GdaSqlExpr* Gnome::Gda::SqlExpr::gobj | ( |  | ) | const
| inline

Provides access to the underlying C instance.

GdaSqlExpr* Gnome::Gda::SqlExpr::gobj_copy | ( |  | ) | const

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

SqlExpr& Gnome::Gda::SqlExpr::operator= | ( | const SqlExpr& | other | ) |

SqlExpr& Gnome::Gda::SqlExpr::operator= | ( | SqlExpr&& | other | ) |
| noexcept

Glib::ustring Gnome::Gda::SqlExpr::serialize | ( |  | ) | const

Creates a new string representing a field.

You need to free the returned string using Glib::free();

Returns
  A new string with the name of the field or "null" in case expr is invalid.

| noexcept

## Friends And Related Function Documentation

void swap | ( | SqlExpr& | lhs,
|  | SqlExpr& | rhs
| ) |  |
| related

Parameters

  lhs | The left-hand side
  rhs | The right-hand side

Gnome::Gda::SqlExpr wrap | ( | GdaSqlExpr * | object,
|  | bool | take_copy = `false`
| ) |  |
| related

A Glib::wrap() method for this object.

Parameters

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns
  A C++ instance that wraps this C instance.
