类 PropertySources

java.lang.Object
cn.taketoday.core.env.PropertySources
所有已实现的接口:
Iterable<PropertySource<?>>
public class PropertySources extends Object implements Iterable<PropertySource<?>>
Holder containing one or more PropertySource objects.

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(cn.taketoday.core.env.PropertySource<?>) and addLast(cn.taketoday.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.
