[CLASS]org.apache.commons.lang.builder.ToStringBuilder

http://commons.apache.org/lang/api-2.5/org/apache/commons/lang/builder/ToStringBuilder.html

This class enables a good and consistent toString() to be built for any class or object. This class aims to simplify the process by:

• allowing field names
• handling all types consistently
• handling nulls consistently
• outputting arrays and multi-dimensional arrays
• enabling the detail level to be controlled for Object and Collections
• handling class hierarchies

Method Summary

• reflectionToString(Object object)

Uses reflectionToString to generate a toString with the specified object; 

• reflectionToString(Object object, ToStringStyle style)

Uses reflectionToString to generate a toString with the specified object;
