StaticdeserializeDeserializes a Tsparql.Resource previously serialized with Resource.serialize. It is implied that both ends use a common NamespaceManager.
StaticnewCreates a binding between source_property on source and target_property
on target.
Whenever the source_property is changed the target_property is
updated using the same value. For instance:
g_object_bind_property (action, "active", widget, "sensitive", 0);
Will result in the "sensitive" property of the widget GObject.Object instance to be updated with the same value of the "active" property of the action GObject.Object instance.
If flags contains GObject.BindingFlags.BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well.
The binding will automatically be removed when either the source or the
target instances are finalized. To remove the binding without affecting the
source and the target you can just call g_object_unref() on the returned
GObject.Binding instance.
Removing the binding by calling g_object_unref() on it must only be done if
the binding, source and target are only used from a single thread and it
is clear that both source and target outlive the binding. Especially it
is not safe to rely on this if the binding, source or target can be
finalized from different threads. Keep another reference to the binding and
use g_binding_unbind() instead to be on the safe side.
A GObject.Object can have multiple bindings.

Complete version of g_object_bind_property().
Creates a binding between source_property on source and target_property
on target, allowing you to set the transformation functions to be used by
the binding.
If flags contains GObject.BindingFlags.BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well. The transform_from function is only used in case
of bidirectional bindings, otherwise it will be ignored
The binding will automatically be removed when either the source or the
target instances are finalized. This will release the reference that is
being held on the GObject.Binding instance; if you want to hold on to the
GObject.Binding instance, you will need to hold a reference to it.
To remove the binding, call g_binding_unbind().
A GObject.Object can have multiple bindings.
The same user_data parameter will be used for both transform_to
and transform_from transformation functions; the notify function will
be called once, when the binding is removed. If you need different data
for each transformation function, please use
g_object_bind_property_with_closures() instead.

This function is intended for GObject.Object implementations to re-enforce
a [floating][floating-ref] object reference. Doing this is seldom
required: all GInitiallyUnowneds are created with a floating reference
which usually just needs to be sunken by calling g_object_ref_sink().
Increases the freeze count on object. If the freeze count is
non-zero, the emission of "notify" signals on object is
stopped. The signals are queued until the freeze count is decreased
to zero. Duplicate notifications are squashed so that at most one
GObject.Object::notify signal is emitted for each property modified while the
object is frozen.
This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.

In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling GObject.Value.unset.

Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class
that registered the property, you should use g_object_notify_by_pspec()
instead.
Note that emission of the notify signal may be blocked with
g_object_freeze_notify(). In this case, the signal emissions are queued
and will be emitted (in reverse order) when g_object_thaw_notify() is
called.
the name of a property installed on the class of object.
Emits a "notify" signal for the property specified by pspec on object.
This function omits the property name lookup, hence it is faster than
g_object_notify().
One way to avoid using g_object_notify() from within the
class that registered the properties, and using g_object_notify_by_pspec()
instead, is to store the GParamSpec used with
g_object_class_install_property() inside a static array, e.g.:
typedef enum
{
PROP_FOO = 1,
PROP_LAST
} MyObjectProperty;
static GParamSpec *properties[PROP_LAST];
static void
my_object_class_init (MyObjectClass *klass)
{
properties[PROP_FOO] = g_param_spec_int ("foo", NULL, NULL,
0, 100,
50,
G_PARAM_READWRITE | G_PARAM_STATIC_STRINGS);
g_object_class_install_property (gobject_class,
PROP_FOO,
properties[PROP_FOO]);
}
and then notify a change on the "foo" property with:
g_object_notify_by_pspec (self, properties[PROP_FOO]);
the GObject.ParamSpec of a property installed on the class of object.
Increases the reference count of object.
Since GLib 2.56, if GLIB_VERSION_MAX_ALLOWED is 2.56 or greater, the type
of object will be propagated to the return type (using the GCC typeof()
extension), so any casting the caller needs to do on the return type must be
explicit.
the same object
Increase the reference count of object, and possibly remove the
[floating][floating-ref] reference, if object has a floating reference.
In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.
Since GLib 2.56, the type of object will be propagated to the return type
under the same conditions as for g_object_ref().
object
Releases all references to other objects. This can be used to break reference cycles.
This function should only be called from object system implementations.
Sets multiple properties of an object at once. The properties argument should be a dictionary mapping property names to values.
Object containing the properties to set
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
If the object already had an association with that name, the old association will be destroyed.
Internally, the key is converted to a GLib.Quark using g_quark_from_string().
This means a copy of key is kept permanently (even after object has been
finalized) — so it is recommended to only use a small, bounded set of values
for key in your program, to avoid the GLib.Quark storage growing unbounded.

the data if found, or null if no such data exists.
This function gets back user data pointers stored via
g_object_set_qdata() and removes the data from object
without invoking its destroy() function (if any was
set).
Usually, calling this function is only required to update
user data pointers with a destroy notifier, for example:
void
object_add_to_user_list (GObject *object,
const gchar *new_string)
{
// the quark, naming the object data
GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
// retrieve the old string list
GList *list = g_object_steal_qdata (object, quark_string_list);
// prepend new string
list = g_list_prepend (list, g_strdup (new_string));
// this changed 'list', so we need to set it again
g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
}
static void
free_string_list (gpointer data)
{
GList *node, *list = data;
for (node = list; node; node = node->next)
g_free (node->data);
g_list_free (list);
}
Using g_object_get_qdata() in the above example, instead of
g_object_steal_qdata() would have left the destroy function set,
and thus the partial string list would have been freed upon
g_object_set_qdata_full().

and when it reaches zero, queued "notify" signals are emitted.
Duplicate notifications for each property are squashed so that at most one GObject.Object::notify signal is emitted for each property, in the reverse order in which they have been queued.
It is an error to call this function when the freeze count is zero.

Decreases the reference count of object. When its reference count
drops to 0, the object is finalized (i.e. its memory is freed).
If the pointer to the GObject.Object may be reused in future (for example, if it is
an instance variable of another object), it is recommended to clear the
pointer to null rather than retain a dangling pointer to a potentially
invalid GObject.Object instance. Use g_clear_object() for this.
Virtualvfunc_the constructed function is called by g_object_new() as the
final step of the object creation process. At the point of the call, all
construction properties have been set on the object. The purpose of this
call is to allow for object initialisation steps that can only be performed
after construction properties have been set. constructed implementors
should chain up to the constructed call of their parent class to allow it
to complete its initialisation.
Virtualvfunc_Virtualvfunc_the dispose function is supposed to drop all references to other
objects, but keep the instance otherwise intact, so that client method
invocations still work. It may be run multiple times (due to reference
loops). Before returning, dispose should chain up to the dispose method
of the parent class.
Virtualvfunc_instance finalization function, should finish the finalization of
the instance begun in dispose and chain up to the finalize method of the
parent class.
Virtualvfunc_Virtualvfunc_Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class
that registered the property, you should use g_object_notify_by_pspec()
instead.
Note that emission of the notify signal may be blocked with
g_object_freeze_notify(). In this case, the signal emissions are queued
and will be emitted (in reverse order) when g_object_thaw_notify() is
called.
Virtualvfunc_the generic setter for all properties of this type. Should be
overridden for every type with properties. If implementations of
set_property don't emit property change notification explicitly, this will
be done implicitly by the type system. However, if the notify signal is
emitted explicitly, the type system will not emit it a second time.
This function essentially limits the life time of the closure to
the life time of the object. That is, when the object is finalized,
the closure is invalidated by calling g_closure_invalidate() on
it, in order to prevent invocations of the closure with a finalized
(nonexisting) object. Also, g_object_ref() and g_object_unref() are
added as marshal guards to the closure, to ensure that an extra
reference count is held on object during invocation of the
closure. Usually, this function will be called on closures that
use this object as closure data.

Tsparql.Resource is an in-memory representation of RDF data about a given resource.
This object keeps track of a set of properties for a given resource, and can also link to other Tsparql.Resource objects to form trees or graphs of RDF data. See Resource.set_relation and Resource.set_uri on how to link a Tsparql.Resource to other RDF data.
Tsparql.Resource may also hold data about literal values, added through the specialized Resource.set_int64, Resource.set_string, etc family of functions, or the generic Resource.set_gvalue method.
Since RDF properties may be multi-valued, for every
setcall there exists anotheraddcall (e.g. Resource.add_int64, Resource.add_string and so on). Thesetmethods do also reset any previously value the property might hold for the given resource.Resources may have an IRI set at creation through Resource.new, or set afterwards through Resource.set_identifier. Resources without a name will represent a blank node, and will be dealt with as such during database insertions.
Tsparql.Resource performs no validation on the data being coherent as per any ontology. Errors will be found out at the time of using the TrackerResource for e.g. database updates.
Once the RDF data is built in memory, the (tree of) Tsparql.Resource may be converted to a RDF format through Resource.print_rdf, or directly inserted into a database through Batch.add_resource or SparqlConnection.update_resource.
