+/**
+ * Generates getters for all fields, a useful toString method, and hashCode and equals implementations that check
+ * all non-transient fields. Will also generate setters for all non-final fields, as well as a constructor.
+ * 
+ * If any method to be generated already exists (in name - the return type or parameters are not relevant), then
+ * that method will not be generated by the Data annotation.
+ * 
+ * <code>toString</code>, <code>equals</code>, and <code>hashCode</code> use the deepX variants in the
+ * <code>java.util.Arrays</code> utility class. Therefore, if your class has arrays that contain themselves,
+ * these methods will just loop endlessly until the inevitable <code>StackOverflowError</code>. This behaviour
+ * is no different from <code>java.util.ArrayList</code>, though.
