Struct GIRepository.BaseInfo

Import line:	GIRepository = imports.gi.GIRepository;
GIR File:	GIRepository-2.0.gir
C documentation:	GIRepository
Struct :	BaseInfo

GIBaseInfo is the common base struct of all other *Info structs
accessible through the GIRepository API.
All other structs can be casted to a GIBaseInfo, for instance:

Casting a <b>GIFunctionInfo</b> to <b>GIBaseInfo</b>

GIFunctionInfo *function_info = ...;
GIBaseInfo *info = (GIBaseInfo*)function_info;

Most GIRepository APIs returning a GIBaseInfo is actually creating a new struct, in other
words, g_base_info_unref() has to be called when done accessing the data.
GIBaseInfos are normally accessed by calling either
g_irepository_find_by_name(), g_irepository_find_by_gtype() or g_irepository_get_info().

Getting the Button of the Gtk typelib

GIBaseInfo *button_info = g_irepository_find_by_name(NULL, "Gtk", "Button");
... use button_info ...
g_base_info_unref(button_info);

Methods / Constructors
Method / Constructor		Defined By
	equal (BaseInfo *info2) : gboolean Compare two GIBaseInfo. Compare two GIBaseInfo. Using pointer comparison is not practical since many functions return different instances of GIBaseInfo* that refers to the same part of the TypeLib; use this function instead to do GIBaseInfo comparisons. Parameters: GIRepository.BaseInfo info2 Required (not null) a GIBaseInfo Returns: gboolean TRUE if and only if info1 equals info2.	GIRepository.BaseInfo
	get_attribute (String *name) : String Retrieve an arbitrary attribute associated with this node. Retrieve an arbitrary attribute associated with this node. Parameters: String name* Required (not null) a freeform string naming an attribute Returns: String The value of the attribute, or NULL if no such attribute exists	GIRepository.BaseInfo
	get_container () : GIRepository.BaseInfo Obtain the container of the info. Obtain the container of the info. The container is the parent GIBaseInfo. For instance, the parent of a GIFunctionInfo is an GIObjectInfo or GIInterfaceInfo. Returns: GIRepository.BaseInfo the container	GIRepository.BaseInfo
	get_name () : String Obtain the name of the info. Obtain the name of the info. What the name represents depends on the GIInfoType of the info. For instance for GIFunctionInfo it is the name of the function. Returns: String the name of info or NULL if it lacks a name.	GIRepository.BaseInfo
	get_namespace () : String Obtain the namespace of info. Obtain the namespace of info. Returns: String the namespace	GIRepository.BaseInfo
	get_typelib () : GIRepository.Typelib Obtain the typelib this info belongs to Obtain the typelib this info belongs to Returns: GIRepository.Typelib the typelib.	GIRepository.BaseInfo
	is_deprecated () : gboolean Obtain whether the info is represents a metadata which is deprecated or not. Obtain whether the info is represents a metadata which is deprecated or not. Returns: gboolean TRUE if deprecated	GIRepository.BaseInfo
	iterate_attributes (AttributeIter *iterator, Object out_values) : gboolean Iterate over all attributes associated with this node. Iterate over all attributes associated with this node. The iterator structure is typically stack allocated, and must have its first member initialized to NULL. Both the name* and value should be treated as constants and must not be freed. Iterating over attributes void print_attributes (GIBaseInfo info) { GIAttributeIter iter = { 0, }; char name; char value; while (g_base_info_iterate_attributes (info, &iter, &name, &value)) { } } Parameters: GIRepository.AttributeIter iterator* Required (not null) a GIAttributeIter structure, must be initialized; see below Object out_values String name String value Returns: gboolean TRUE if there are more attributes	GIRepository.BaseInfo
