Virtual Method
GeglMetadataStore_declare
Declaration [src]
void
_declare (
  GeglMetadataStore* self,
  GParamSpec* pspec,
  gboolean shadow
)
Description [src]
The _declare virtual method creates a metadata variable in the
underlying data store. It implements gegl_metadata_store_declare(). A
GParamSpec is used to describe the variable.  If the metadata shadows an
object property, shadow should be TRUE, otherwise FALSE.  It is acceptable
for a subclass to provide additional variables which are implicitly
declared, that is, they need not be declared using
gegl_metadata_store_declare(), however the pspec method must still retrieve a GParamSpec describing such variables.  This method MUST be provided by
the subclass.
Parameters

            Type: GParamSpecNo description available. The data is owned by the caller of the method.
