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

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

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.
void Gnome::Gda::SqlExpr::swap ( SqlExpr other)
noexcept

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

Parameters
objectThe C instance.
take_copyFalse 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.
