Detailed Description

Object's parameters is a special Midgard feature which allows to extend object's data by storing object's parameters identified by domain, name and value via midgard_parameter type.

The main purpose of parameters is to assign some values to object without any need to set these values as typical object's properties.

gboolean midgard_object_set_parameter (  MgdObject *  self, const gchar *  domain, const gchar *  name, GValue *  value, gboolean  lang )

Set object's parameter. Parameters: self,MgdObject  instance [in]  domain,parameter's  domain string [in]  name,paramater's  name string [in]  value,a  GValue value which should be set for domain&name pair [in]  lang,boolean  which determines if default language should be forced Returns: TRUE on success, FALSE otherwise Success means that parameter object is created if it doesn't exist, or is updated otherwise.
