Examples of org.apache.commons.lang3.builder.CompareToBuilder

org.apache.commons.lang3.reflect.testbed.PubliclyShadowedChild
Assists in implementing {@link java.lang.Comparable#compareTo(Object)} methods.It is consistent with equals(Object) and hashcode() built with {@link EqualsBuilder} and{@link HashCodeBuilder}.

Two Objects that compare equal using equals(Object) should normally also compare equal using compareTo(Object).

All relevant fields should be included in the calculation of the comparison. Derived fields may be ignored. The same fields, in the same order, should be used in both compareTo(Object) and equals(Object).

To use this class write code as follows:
```
 public class MyClass { String field1; int field2; boolean field3; ... public int compareTo(Object o) { MyClass myClass = (MyClass) o; return new CompareToBuilder() .appendSuper(super.compareTo(o) .append(this.field1, myClass.field1) .append(this.field2, myClass.field2) .append(this.field3, myClass.field3) .toComparison(); } } 
```
Alternatively, there are {@link #reflectionCompare(Object,Object) reflectionCompare} methods that usereflection to determine the fields to append. Because fields can be private, reflectionCompare uses {@link java.lang.reflect.AccessibleObject#setAccessible(boolean)} tobypass normal access control checks. This will fail under a security manager, unless the appropriate permissions are set up correctly. It is also slower than appending explicitly.

A typical implementation of compareTo(Object) using reflectionCompare looks like:
```
 public int compareTo(Object o) { return CompareToBuilder.reflectionCompare(this, o); } 
```
