Detailed Description

Row for a Gda::DataModelArray object.

The GdaDataModelArray object uses GdaRow to store each row of data. Each GdaRow has the same number of GValue values (equal to the number of columns of the data model).

As a side note, the GdaRow object is also used internally by the implementation of the data models returned when executing a SELECT statement.

Member Function Documentation

static Glib::RefPtr<Row> Gnome::Gda::Row::create ( int  count)
static
int Gnome::Gda::Row::get_length ( )
Returns
The number of columns that the row has.
static GType Gnome::Gda::Row::get_type ( )
static

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

Value Gnome::Gda::Row::get_value ( int  num)

Gets a pointer to a Value stored in a Gda::Row.

This is a pointer to the internal array of values. Don't try to free or modify it (modifying is reserved to database provider's implementations).

Parameters
numField index.
Returns
A pointer to the Value in the position num of row.
GdaRow* Gnome::Gda::Row::gobj ( )
inline

Provides access to the underlying C GObject.

const GdaRow* Gnome::Gda::Row::gobj ( ) const
inline

Provides access to the underlying C GObject.

GdaRow* Gnome::Gda::Row::gobj_copy ( )

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

Friends And Related Function Documentation

Glib::RefPtr< Gnome::Gda::Row > wrap ( GdaRow *  object,
bool  take_copy = false 
)
related

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.
