- /**
- * <p>Assists in implementing {@link Object#equals(Object)} methods.</p>
- *
- * <p> This class provides methods to build a good equals method for any
- * class. It follows rules laid out in
- * <a href="http://java.sun.com/docs/books/effective/index.html">Effective Java</a>
- * , by Joshua Bloch. In particular the rule for comparing <code>doubles</code>,
- * <code>floats</code>, and arrays can be tricky. Also, making sure that
- * <code>equals()</code> and <code>hashCode()</code> are consistent can be
- * difficult.</p>
- *
- * <p>Two Objects that compare as equals must generate the same hash code,
- * but two Objects with the same hash code do not have to be equal.</p>
- *
- * <p>All relevant fields should be included in the calculation of equals.
- * Derived fields may be ignored. In particular, any field used in
- * generating a hash code must be used in the equals method, and vice
- * versa.</p>
- *
- * <p>Typical use for the code is as follows:</p>
- * <pre>
- * public boolean equals(Object o) {
- * if ( !(o instanceof MyClass) ) {
- * return false;
- * }
- * MyClass rhs = (MyClass) o;
- * return new EqualsBuilder()
- * .appendSuper(super.equals(o))
- * .append(field1, rhs.field1)
- * .append(field2, rhs.field2)
- * .append(field3, rhs.field3)
- * .isEquals();
- * }
- * </pre>
- *
- * <p> Alternatively, there is a method that uses reflection to determine
- * the fields to test. Because these fields are usually private, the method,
- * <code>reflectionEquals</code>, uses <code>AccessibleObject.setAccessible</code> to
- * change the visibility of the fields. This will fail under a security
- * manager, unless the appropriate permissions are set up correctly. It is
- * also slower than testing explicitly.</p>
- *
- * <p> A typical invocation for this method would look like:</p>
- * <pre>
- * public boolean equals(Object o) {
- * return EqualsBuilder.reflectionEquals(this, o);
- * }
- * </pre>
