Assists in implementing {@link Object#toString()} methods.

+ * + *

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

+ * + * + *

To use this class write code as follows:

+ * + * 
+ * public class Person {
+ *   String name;
+ *   int age;
+ *   boolean smoker;
+ *
+ *   ...
+ *
+ *   public String toString() {
+ *     return new ToStringBuilder(this).
+ *       append("name", name).
+ *       append("age", age).
+ *       append("smoker", smoker).
+ *       toString();
+ *   }
+ * }
+ *
+ * + *

This will produce a toString of the format: + * Person@7f54[name=Stephen,age=29,smoker=false]

+ * + *

To add the superclass toString, use {@link #appendSuper}. + * To append the toString from an object that is delegated + * to (or any other object), use {@link #appendToString}.

+ * + *

Alternatively, there is a method that uses reflection to determine + * the fields to test. Because these fields are usually private, the method, + * reflectionToString, uses AccessibleObject.setAccessible 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.

+ * + *

A typical invocation for this method would look like:

+ * + * 
+ * public String toString() {
+ *   return ToStringBuilder.reflectionToString(this);
+ * }
+ *
+ * + *

You can also use the builder to debug 3rd party objects:

+ * + * 
+ * System.out.println("An object: " + ToStringBuilder.reflectionToString(anObject));
+ *
+ * + *

The exact format of the toString is determined by + * the {@link ToStringStyle} passed into the constructor.

+ * + * @since 1.0 + * @version $Id: ToStringBuilder.java 1088899 2011-04-05 05:31:27Z bayard $ + */ +public class ToStringBuilder implements Builder { + + /** + * The default style of output to use, not null. + */ + private static volatile ToStringStyle defaultStyle = ToStringStyle.DEFAULT_STYLE; + + //---------------------------------------------------------------------------- + + /** + *
