+/**
+ ** BeanInfo can be implemented in order to provide explicit information to the Introspector.
+ **
+ ** When you write a BeanInfo class, you implement this interface
+ ** and provide explicit information by returning a non-null
+ ** value from the appropriate method.  If you wish the
+ ** Introspector to determine certain information in the normal
+ ** way, just return null (or in the case of int methods, return
+ ** -1).  There is a class called SimpleBeanInfo which returns
+ ** null from all methods, which you may extend and only
+ ** override the methods you wish to override.<P>
+ **
+ ** When you have written the class, give it the name
+ ** <CODE>&lt;Bean Class Name&gt;BeanInfo</CODE> and place it in
+ ** the same package as the Bean, or in the bean info search path
+ ** (see Introspector for information on search paths).<P>
+ **
+ ** A simple note about the way the Introspector interacts with
+ ** BeanInfo.  Introspectors look at a Bean class and determine
+ ** if there is a BeanInfo class with it.  If there is not a
+ ** BeanInfo class, it will behave as if the BeanInfo class
+ ** provided was a SimpleBeanInfo class (i.e. it will determine
+ ** all information automatically).<P>If there is a BeanInfo
+ ** class, then any methods that do *not* return null are
+ ** regarded as providing definitive information about the class
+ ** and all of its superclasses for those information types.
+ ** Even if a parent BeanInfo class explicitly returns that
+ ** information, it will not be used.

+   *

+   * a no-argument method on a given instance for <strong>each</strong>
+   * method of the listener interface.</p>
+   * 
+   * <p>Note: The <code>action</code> is interpreted as a method name. If your target object

+   * real method here is wrong and will throw an <code>ArrayIndexOutOfBoundsException</code>
+   * whenever one of the listener methods is called.<p/>
+   *
+   * <p>The <code>EventHandler</code> will automatically convert primitives

+   * and applies it to the target's property or method. This first argument
+   * of the listener is usually an event object but any other object is
+   * valid, too.</p>
+   * 
+   * <p>You can set the value of <code>eventPropertyName</code> to "prop"

+   * object. In case that no such property exists the <code>EventHandler</code>
+   * will try to find a method with that name.</p>
+   * 
+   * <p>If you set <code>eventPropertyName</code> to a value like this "a.b.c"
+   * <code>EventHandler</code> will recursively evaluate the properties "a", "b"
+   * and "c". Again if no property can be found the <code>EventHandler</code>
+   * tries a method name instead. This allows mixing the names, too: "a.toString"
+   * will retrieve the property "a" from the event object and will then call
+   * the method "toString" on it.</p>
+   * 
+   * <p>An exception thrown in any of these methods will provoke a
+   * <code>RuntimeException</code> to be thrown which contains an
+   * <code>InvocationTargetException</code> containing the triggering exception.</p>
+   * 
+   * <p>If you set <code>eventPropertyName</code> to a non-null value the
+   * <code>action</code> parameter will be interpreted as a property name
+   * or a method name of the target object.</p>
+   *   
+   * <p>Any object retrieved from the event object and applied to the
+   * target will converted from primitives to their wrapper class or
+   * vice versa or applied to a method that accepts a superclass
+   * of the object.</p>
+   *
+   * <p>Examples:</p>
+   * <p>The following code:</p><code>

+   *            textField.setText((String) o);
+   *        }
+   *    });
+   * </code>
+   * 
+   * <p>Can be expressed using the <code>EventHandler</code> like this:</p>
+   * <p>
+   * <code>button.addActionListener((ActionListener)
+   *    EventHandler.create(ActionListener.class, textField, "text", "source.class.name");
+   * <code>
+   * </p>
+   * 
+   * <p>As said above you can specify the target as a method, too:</p>
+   * <p>
+   * <code>button.addActionListener((ActionListener)
+   *    EventHandler.create(ActionListener.class, textField, "setText", "source.class.name");
+   * <code>
+   * </p>
+   * 
+   * <p>Furthermore you can use method names in the property:</p>
+   * <p>
+   * <code>button.addActionListener((ActionListener)
+   *    EventHandler.create(ActionListener.class, textField, "setText", "getSource.getClass.getName");
+   * <code>
+   * </p>

+ **
+ ** The methods have these constraints on them:<P>

+ ** parameters and exceptions are allowed.  May be public, protected or
+ ** package-protected. (Don't ask me why that is, I'm just following the spec.
+ ** The only place it is even mentioned is in the Java Beans white paper, and
+ ** there it is only implied.)</LI>
+ ** <LI>add listener method: must have <CODE>void</CODE> return value.  Must
+ ** take exactly one argument, of the listener class's type.  May fire either
+ ** zero exceptions, or one exception of type <CODE>java.util.TooManyListenersException</CODE>.
+ ** Must be public.</LI>

+ ** Must take exactly one argument, of the listener class's type.  May not
+ ** fire any exceptions.  Must be public.</LI>

+/**
+ * Introspector is the class that does the bulk of the
+ * design-time work in Java Beans.  Every class must have
+ * a BeanInfo in order for an RAD tool to use it; but, as
+ * promised, you don't have to write the BeanInfo class
+ * yourself if you don't want to.  All you have to do is
+ * call getBeanInfo() in the Introspector and it will use
+ * standard JavaBeans-defined method signatures to
+ * determine the information about your class.<P>
+ *
+ * Don't worry about it too much, though: you can provide
+ * JavaBeans with as much customized information as you
+ * want, or as little as you want, using the BeanInfo
+ * interface (see BeanInfo for details).<P>
+ *
+ * <STRONG>Order of Operations</STRONG><P>
+ *
+ * When you call getBeanInfo(class c), the Introspector
+ * first searches for BeanInfo class to see if you
+ * provided any explicit information.  It searches for a
+ * class named &lt;bean class name&gt;BeanInfo in different
+ * packages, first searching the bean class's package
+ * and then moving on to search the beanInfoSearchPath.<P>
+ *
+ * If it does not find a BeanInfo class, it acts as though
+ * it had found a BeanInfo class returning null from all
+ * methods (meaning it should discover everything through
+ * Introspection).  If it does, then it takes the
+ * information it finds in the BeanInfo class to be
+ * canonical (that is, the information speaks for its
+ * class as well as all superclasses).<P>
+ *
+ * When it has introspected the class, calls
+ * getBeanInfo(c.getSuperclass) and adds that information
+ * to the information it has, not adding to any information
+ * it already has that is canonical.<P>
+ *
+ * <STRONG>Introspection Design Patterns</STRONG><P>
+ *
+ * When the Introspector goes in to read the class, it
+ * follows a well-defined order in order to not leave any
+ * methods unaccounted for.  Its job is to step over all
+ * of the public methods in a class and determine whether
+ * they are part of a property, an event, or a method (in
+ * that order).
+ *
+ *
+ * <STRONG>Properties:</STRONG><P>
+ * 
+ * <OL>
+ * <LI>If there is a <CODE>public boolean isXXX()</CODE>
+ *     method, then XXX is a read-only boolean property.
+ *     <CODE>boolean getXXX()</CODE> may be supplied in
+ *     addition to this method, although isXXX() is the
+ *     one that will be used in this case and getXXX()
+ *     will be ignored.  If there is a
+ *     <CODE>public void setXXX(boolean)</CODE> method,
+ *     it is part of this group and makes it a read-write
+ *     property.</LI>
+ * <LI>If there is a
+ *     <CODE>public &lt;type&gt; getXXX(int)</CODE>
+ *     method, then XXX is a read-only indexed property of

+ *     <CODE>public void setXXX(int,&lt;type&gt;)</CODE>
+ *     method, then it is a read-write indexed property of
+ *     type &lt;type&gt;.  There may also be a
+ *     <CODE>public &lt;type&gt;[] getXXX()</CODE> and a
+ *     <CODE>public void setXXX(&lt;type&gt;)</CODE>
+ *     method as well.</LI>

+ *     &lt;type&gt;.  If there is a
+ *     <CODE>public void setXXX(&lt;type&gt;)</CODE>
+ *     method, then it will be used for the property and
+ *     the property will be considered read-write.</LI>
+ * <LI>If there is a
+ *     <CODE>public void setXXX(&lt;type&gt;)</CODE>
+ *     method, then as long as XXX is not already used as
+ *     the name of a property, XXX is assumed to be a
+ *     write-only property of type &lt;type&gt;.</LI>
+ * <LI>In all of the above cases, if the setXXX() method
+ *     throws <CODE>PropertyVetoException</CODE>, then the
+ *     property in question is assumed to be constrained.
+ *     No properties are ever assumed to be bound
+ *     (<STRONG>Spec Note:</STRONG> this is not in the
+ *     spec, it just makes sense).  See PropertyDescriptor
+ *     for a description of bound and constrained
+ *     properties.</LI>

+ * methods imply that this Bean will fire events to
+ * listeners of type &lt;type&gt;.<P>
+ *

+/**
+ ** PropertyEditors are custom GUI editors for specific types of values.
+ **
+ ** A PropertyEditor can be used, for example, if you are editing a type of value
+ ** that can be more easily represented graphically, such as a Point, or one that
+ ** can be more easily represented by a list, such as a boolean (true/false).<P>
+ **
+ ** A PropertyEditor must be able to display its contents when asked to and
+ ** be able to allow the user to change its underlying field value.  However, it
+ ** is not the PropertyEditor's responsibility to make the change to the
+ ** underlying Object; in fact, the PropertyEditor does not even know about the
+ ** Object it is actually editing--only about the property it is currently
+ ** editing.  When a change is made to the property, the PropertyEditor must
+ ** simply fire a PropertyChangeEvent and allow the RAD tool to actually set
+ ** the property in the underlying Bean.<P>
+ **
+ ** PropertyEditors should not change the Objects they are given by setValue().
+ ** These Objects may or may not be the actual Objects which are properties of
+ ** the Bean being edited.  Instead, PropertyEditors should create a new Object
+ ** and fire a PropertyChangeEvent with the old and new values.<P>
+ **
+ ** PropertyEditors also must support the ability to return a Java
+ ** initialization string.  See the getJavaInitializationString() method for
+ ** details.<P>
+ **
+ ** There are several different ways a PropertyEditor may display and control
+ ** editing of its value.  When multiple types of input and display are
+ ** given by a single PropertyEditor, the RAD tool may decide which of the call
+ ** to support.  Some RAD tools may even be text-only, so even if you support
+ ** a graphical set and get, it may choose the text set and get whenever it can.
+ ** <OL>
+ **   <LI>Every PropertyEditor must support getValue() and setValue().  For
+ **       setValue(), the component must only support it when the argument is
+ **       the same type that the PropertyEditor supports.</LI>
+ **   <LI>Every PropertyEditor must support getJavaInitializationString().</LI>
+ **   <LI>You may support painting the value yourself if you wish.  To do this,
+ **       have isPaintable() return true and implement the paintValue() method.
+ **       This method does not determine in any way how the value is edited;
+ **       merely how it is displayed.</LI>
+ **   <LI>Let the caller of the PropertyEditor give the user a text input.  Do
+ **       this by returning a non-null String from getAsText().  If you support
+ **       text input, you *must* support setAsText().</LI>
+ **   <LI>Give the caller a set of possible values, such as "true"/"false", that
+ **       the user must select from.  To do this, return the list of Strings
+ **       from the getTags() method.  The RAD tool may choose to implement the
+ **       user input any way it wishes, and only guarantees that setAsText() will
+ **       only be called with one of the Strings returned from getTags().</LI>
+ **   <LI>You may support a whole custom editing control by supporting
+ **       getCustomEditor().  To do this, return true from supportsCustomEditor()
+ **       and return a Component that does the job.  It is the component's job,
+ **       or the PropertyEditor's job, to make sure that when the editor changes
+ **       its value, the PropertyChangeEvent is thrown.</LI>
+ ** </OL>
+ **
+ ** The PropertyEditor for a particular Bean can be found using the
+ ** PropertyEditorManager class, which goes through a series of different
+ ** checks to find the appropriate class.<P>
+ **
+ ** A PropertyChangeEvent should be thrown from the PropertyEditor whenever a
+ ** bound  property (a property PropertyDescriptor.isBound() set to true)
+ ** changes.  When this happens, the editor itself should *not* change the value
+ ** itself, but rather allow the RAD tool to call setValue() or setAsText().

+ * The XMLDecoder reads XML data that is structured according to

+ * and creates objects according to the content. Usually such data is generated using the
+ * {@link XMLEncoder} class.
+ * <p>
+ * An example XML document might look like this:
+ * <code>
+ * &lt;java&gt;
+ * 	&lt;string&gt;Hello World&lt;/string&gt;
+ * 	&lt;int&gt;200&lt;/int&gt;
+ * &lt;/java&gt;
+ * </code>
+ * <p>To read the <code>String</code> and the <code>Integer</code> instance the following can be used (assume
+ * the XML data can be obtained from the InputStream):</p>
+ * <code>
+ * XMLDecoder decoder = new XMLDecoder(inputStreamContainingXMLData);
+ * String message = (String) decoder.readObject();
+ * Integer number = (Integer) decoder.readObject();
+ * </code>
+ * <p>Besides this basic functionality the <code>XMLDecoder</code> has some more features that might come
+ * handy in certain situations:</p>
+ * <p>An owner object can be set using the <code>setOwner</code> method which can then be accessed when
+ * decoding. This feature is only useful if the XML data is aware of the owner object. Such data may
+ * look like this (assume that the owner object is a JFrame instance):</p>
+ * <code> 
+ * &lt;java&gt;
+ * 	&lt;void method="getOwner"&gt;
+ * 		&lt;void method="setVisible"&gt;
+ * 			&lt;boolean&gt;true&lt;boolean&gt;
+ * 		&lt;/void&gt;
+ *  &lt;/void&gt;
+ * &lt;/java&gt;
+ * </code>
+ * This accesses the <code>JFrame</code> and makes it visible using the <code>setVisible</code> method.
+ * <p>Please note that changing the owner <b>after</b> the having read the first object has no effect,
+ * because all object have been decoded then.</p>
+ * <p>If the <code>XMLDecoder</code> is created with no {@link ExceptionListener} instance a default one
+ * is used that prints an error message to <code>System.err</code> whenever a recoverable exception
+ * is thrown. Recovarable exceptions occur when the XML data cannot be interpreted correctly (e.g
+ * unknown classes or methods, invocation on null, ...). In general be very careful when the
+ * <code>XMLDecoder</code> provoked such exceptions because the resulting object(s) may be in an
+ * undesirable state.</p>
+ * <p>Note that changing the ExceptionListener instance after <code>readObject</code> has been called
+ * once has no effect because the decoding is completed then.</p>
+ * <p>At last one can provide a specific <code>ClassLoader</code> which is then used when <code>Class</code>
+ * objects are accessed. See {@link java.lang.Class#forName(String, boolean, ClassLoader)} for details
+ * on this.</p>
+ * <p>Note: If the <code>InputStream</code> instance given to any of the constructors is <code>null</code>
+ * the resulting <code>XMLDecoder</code> will be silently (without any exception) useless. Each call
+ * to <code>readObject</code> will return <code>null</code> and never throws an
+ * <code>ArrayIndexOutOfBoundsException</code>.</p>
