Object_info — Struct representing a GObject
Object_info represents a GObject. This doesn't represent a specific instance of a GObject, instead this represent the object type (eg class). A GObject has methods, fields, properties, signals, interfaces, constants and virtual functions.
val objectinfo : t Ctypes.structure Ctypes.typval get_abstract : t Ctypes.structure Ctypes.ptr -> boolObtain if the object type is an abstract type, eg if it cannot be instantiated
val get_fundamental : t Ctypes.structure Ctypes.ptr -> boolObtain if the object type is of a fundamental type which is not G_TYPE_OBJECT. This is mostly for supporting GstMiniObject.
val get_parent :
t Ctypes.structure Ctypes.ptr ->
Base_info.t Ctypes.structure Ctypes.ptrObtain the parent of the object type.
val get_type_name : t Ctypes.structure Ctypes.ptr -> stringObtain the name of the objects class/type.
val get_type_init : t Ctypes.structure Ctypes.ptr -> stringObtain the function which when called will return the GType function for which this object type is registered.
val get_n_constants : t Ctypes.structure Ctypes.ptr -> intObtain the number of constants that this object type has.
val get_constant :
t Ctypes.structure Ctypes.ptr ->
int ->
Constant_info.t Ctypes.structure Ctypes.ptrObtain an object type constant at index n .
val get_n_fields : t Ctypes.structure Ctypes.ptr -> intObtain the number of fields that this object type has.
val get_field :
t Ctypes.structure Ctypes.ptr ->
int ->
Field_info.t Ctypes.structure Ctypes.ptrObtain an object type field at index n .
val get_n_interfaces : t Ctypes.structure Ctypes.ptr -> intObtain the number of interfaces that this object type has.
val get_interface :
t Ctypes.structure Ctypes.ptr ->
int ->
Interface_info.t Ctypes.structure Ctypes.ptrObtain an object type interface at index n .
val get_n_methods : t Ctypes.structure Ctypes.ptr -> intObtain the number of methods that this object type has.
val get_method :
t Ctypes.structure Ctypes.ptr ->
int ->
Function_info.t Ctypes.structure Ctypes.ptrObtain an object type method at index n .
val find_method :
t Ctypes.structure Ctypes.ptr ->
string ->
Function_info.t Ctypes.structure Ctypes.ptr optionObtain a method of the object type given a name . None will be returned if there's no method available with that name.
val get_n_properties : t Ctypes.structure Ctypes.ptr -> intObtain the number of properties that this object type has.
val get_property :
t Ctypes.structure Ctypes.ptr ->
int ->
Property_info.t Ctypes.structure Ctypes.ptrObtain an object type property at index n .
val get_n_signals : t Ctypes.structure Ctypes.ptr -> intObtain the number of signals that this object type has.
val get_signal :
t Ctypes.structure Ctypes.ptr ->
int ->
Signal_info.t Ctypes.structure Ctypes.ptrObtain an object type signal at index n .
val find_signal :
t Ctypes.structure Ctypes.ptr ->
string ->
Signal_info.t Ctypes.structure Ctypes.ptr optionFind a signal with a name.
val get_n_vfuncs : t Ctypes.structure Ctypes.ptr -> intObtain the number of virtual functions that this object type has.
val get_vfunc :
t Ctypes.structure Ctypes.ptr ->
int ->
VFunc_info.t Ctypes.structure Ctypes.ptrObtain an object type virtual function at index n .
val find_vfunc :
t Ctypes.structure Ctypes.ptr ->
string ->
VFunc_info.t Ctypes.structure Ctypes.ptr optionLocate a virtual function slot with name name . Note that the namespace for virtuals is distinct from that of methods; there may or may not be a concrete method associated for a virtual. If there is one, it may be retrieved using VFunc_info.get_invoker, otherwise None will be returned. See the documentation for VFunc_info.get_invoker for more information on invoking virtuals.
val get_class_struct :
t Ctypes.structure Ctypes.ptr ->
Struct_info.t Ctypes.structure Ctypes.ptr optionEvery GObject has two structures; an instance structure and a class structure. This function returns the metadata for the class structure. It returns a Struct_info.t or None.
val find_method_using_interfaces :
t Ctypes.structure Ctypes.ptr ->
string ->
Function_info.t Ctypes.structure Ctypes.ptr option
* t Ctypes.structure Ctypes.ptr optionObtain a method of the object given a name , searching both the object info and any interfaces it implements. None will be returned if there's no method available with that name. Note that this function does *not* search parent classes; you will have to chain up if that's desired.
val get_ref_function : t Ctypes.structure Ctypes.ptr -> string optionObtain the symbol name of the function that should be called to ref this object type. It's mainly used fundamental types. The type signature for the symbol is Object_infoRefFunction, to fetch the function pointer see Object_info.get_ref_function.
val get_unref_function : t Ctypes.structure Ctypes.ptr -> string optionObtain the symbol name of the function that should be called to unref this object type. It's mainly used fundamental types. The type signature for the symbol is Object_infoUnrefFunction, to fetch the function pointer see Object_info.get_unref_function.
val get_set_value_function : t Ctypes.structure Ctypes.ptr -> string optionObtain the symbol name of the function that should be called to convert set a GValue giving an object instance pointer of this object type. I's mainly used fundamental types. The type signature for the symbol is Object_infoSetValueFunction, to fetch the function pointer see Object_info.get_set_value_function.
val get_get_value_function : t Ctypes.structure Ctypes.ptr -> string optionObtain the symbol name of the function that should be called to convert an object instance pointer of this object type to a GValue. I's mainly used fundamental types. The type signature for the symbol is Object_infoGetValueFunction, to fetch the function pointer see Object_info.get_get_value_function.
val find_vfunc_using_interfaces :
t Ctypes.structure Ctypes.ptr ->
string ->
VFunc_info.t Ctypes.structure Ctypes.ptr option
* t Ctypes.structure Ctypes.ptr optionLocate a virtual function slot with name name , searching both the object info and any interfaces it implements. Note that the namespace for virtuals is distinct from that of methods; there may or may not be a concrete method associated for a virtual. If there is one, it may be retrieved using g_vfunc_info_get_invoker(), otherwise None will be returned. Note that this function does *not* search parent classes; you will have to chain up if that's desired.
