ESourceExtension is an abstract base class for ESource extension objects. An ESourceExtension object basically just maps the keys in a key file group to a set of GObject properties. The name of the key file group doubles as the name of the ESourceExtension object.
ESourceExtension objects are accessed through e_source_get_extension().
struct ESourceExtension;
Contains only private data that should be read and manipulated using the functions below.
Since 3.6
#define E_SOURCE_PARAM_SETTING (1 << G_PARAM_USER_SHIFT)
Extends GParamFlags to indicate the GObject property is associated with a key file value. Use this flag when installing GObject properties in ESourceExtension subclasses.
Since 3.6
ESource *           e_source_extension_ref_source       (ESourceExtension *extension);
Returns the ESource instance to which the extension belongs.
The returned ESource is referenced for thread-safety.  Unreference
the ESource with g_object_unref() when finished with it.

| Returns : | the ESource instance | 
Since 3.8
ESource *           e_source_extension_get_source       (ESourceExtension *extension);
e_source_extension_get_source has been deprecated since version 3.8 and should not be used in newly-written code. Use e_source_extension_ref_source() instead.
Returns the ESource instance to which extension belongs.
Note this function is not thread-safe. The returned ESource could be finalized by another thread while the caller is still using it.
