svn commit: r1804639 - in
/ofbiz/ofbiz-framework/trunk/framework/base/src/main/java/org/apache/ofbiz/base/config:
MainResourceHandler.java ResourceLoader.java
Author: jleroux
Date: Thu Aug 10 07:52:16 2017
New Revision: 1804639
URL: http://svn.apache.org/viewvc?rev=1804639&view=rev
Log:
Improved: [FB] Package org.apache.ofbiz.base.config
(OFBIZ-9566)
MainResourceHandler
The protected fields were set to private since the class is not extended
anywhere. If they need to be accessed in the future, getter that return an
unmodifiable version should be implemented (Collections.unmodifiableXXX).
Refactor:
Uses multi exceptions catch (explicitly to not catch, hence somehow swallow,
RuntimeException)
Uses return instead of else when appropriate
Extracts a getLoader() handy method
Removes an useless thrown exception in invalidateDocument()
Removes an useless Document cast
Removes an useless ResourceLoader null initialisation
