      • setProperties

        public static void setProperties​(Object bean,
                                 Map<String,​String> properties)
        Sets the properties of a Java Bean based on the String name/value pairs in the specifieed Map. Because this method has to know how to convert a String value into the correct type for the bean, only a few bean property types are supported. They are: String, boolean, int, long, float, double, Color, and Class.

        If key/value pairs exist in the Map that don't correspond to properties of the bean, they will be ignored.

        Parameters:
        bean - the JavaBean to set properties on.
        properties - String name/value pairs of the properties to set.

      • setProperties

        public static void setProperties​(Object bean,
                                 javax.servlet.http.HttpServletRequest request)
        Sets the properties of a Java Bean based on the request's properties. Because this method has to know how to convert a String value into the correct type for the bean, only a few bean property types are supported. They are: String, boolean, int, long, float, double, Color, and Class.

        If key/value pairs exist in the Map that don't correspond to properties of the bean, they will be ignored.

        Parameters:
        bean - the JavaBean to set properties on.
        request - the HTTP request.

      • getProperties

        public static Map<String,​String> getProperties​(Object bean)
        Gets the properties from a Java Bean and returns them in a Map of String name/value pairs. Because this method has to know how to convert a bean property into a String value, only a few bean property types are supported. They are: String, boolean, int, long, float, double, Color, and Class.
        Parameters:
        bean - a Java Bean to get properties from.
        Returns:
        a Map of all properties as String name/value pairs.

      • getPropertyDescriptors

        public static PropertyDescriptor[] getPropertyDescriptors​(Class beanClass)
                                                   throws IntrospectionException
        Returns the PropertyDescriptor array for the specified Java Bean Class. The method also does a special check to see of the bean has a BeanInfo class that extends the JiveBeanInfo class. If yes, we load the PropertyDescriptor array directly from that BeanInfo class rather than through the Introspector in order to preserve the desired ordering of properties.
        Parameters:
        beanClass - the Class of the JavaBean.
        Returns:
        the PropertyDescriptor array for the specified Java Bean Class.
        Throws:
        IntrospectionException - if there were problems accessing the descriptor
