public class MutablePropertySources extends Object implements PropertySources
PropertySources
interface.
Allows manipulation of contained property sources and provides a constructor
for copying an existing PropertySources
instance.
Where precedence is mentioned in methods such as addFirst(org.springframework.core.env.PropertySource<?>)
and addLast(org.springframework.core.env.PropertySource<?>)
, this is with regard to the order in which property sources
will be searched when resolving a given property with a PropertyResolver
.
