JanaComponent

typedef struct _JanaComponent JanaComponent;

The JanaComponent struct contains only private data.

enum JanaComponentType

typedef enum {
	JANA_COMPONENT_NULL,
	JANA_COMPONENT_EVENT,
	JANA_COMPONENT_NOTE,
	JANA_COMPONENT_TASK,
} JanaComponentType;

Enum values for different types of component.

jana_component_get_component_type ()

JanaComponentType   jana_component_get_component_type   (JanaComponent *self);

Get the JanaComponentType of self. The component type will tell you if the component can be cast to a more specific type.

jana_component_is_fully_represented ()

gboolean            jana_component_is_fully_represented (JanaComponent *self);

Determines whether the underlying data of self is fully represented by the libjana interface. If it isn't, there may be data in the component that is not reachable via libjana and modifying the object may destroy this data.

jana_component_get_uid ()

gchar*              jana_component_get_uid              (JanaComponent *self);

Get a unique identifying string for self. This can be used as the key in a hash table and does not change when modifying the component. A JanaComponent that is not a part of a JanaStore may not have a uid.

This function returns a newly allocated string. To avoid this allocation please use jana_component_peek_uid().

jana_component_get_categories ()

gchar**             jana_component_get_categories       (JanaComponent *self);

Retrieves the list of categories this component is filed under. See jana_component_set_categories().

jana_component_set_categories ()

void                jana_component_set_categories       (JanaComponent *self,
                                                         const gchar **categories);

Sets or clears the component's category list, overriding any previous set. list. categories should be an array of NULL-terminated UTF-8 strings, and the final member of the array should be NULL.

jana_component_supports_custom_props ()

gboolean            jana_component_supports_custom_props
                                                        (JanaComponent *self);

Determines whether self supports the setting and retrieval of custom properties.

jana_component_get_custom_props_list ()

GList*              jana_component_get_custom_props_list
                                                        (JanaComponent *self);

Get a GList of properties set on self. The data component of each list element contains an array of two strings. The first string is the property name, the second the value. This list can be freed using jana_component_props_list_free().

jana_component_get_custom_prop ()

gchar*              jana_component_get_custom_prop      (JanaComponent *self,
                                                         const gchar *name);

Retrieve a custom property set on self.

jana_component_set_custom_prop ()

gboolean            jana_component_set_custom_prop      (JanaComponent *self,
                                                         const gchar *name,
                                                         const gchar *value);

Set a property on self. If the property has been set previously, the value will be overwritten. Implementations of JanaComponent may require that property names conform to a particular specification.

jana_component_props_list_free ()

void                jana_component_props_list_free      (GList *props);

Frees a JanaComponent property list, returned by jana_component_get_custom_props_list().
