## Class ObjectView

- java.lang.Object
- - javax.swing.text.View
  - - javax.swing.text.ComponentView
    - - javax.swing.text.html.ObjectView

- All Implemented Interfaces:
    SwingConstants

      public class ObjectView
      extends ComponentView

  Component decorator that implements the view interface for <object> elements.

  This view will try to load the class specified by the `classid` attribute. If possible, the Classloader used to load the associated Document is used. This would typically be the same as the ClassLoader used to load the EditorKit. If the document's ClassLoader is null, `Class.forName` is used.

  If the class can successfully be loaded, an attempt will be made to create an instance of it by calling `Class.newInstance`. An attempt will be made to narrow the instance to type `java.awt.Component` to display the object.

  This view can also manage a set of parameters with limitations. The parameters to the <object> element are expected to be present on the associated elements attribute set as simple strings. Each bean property will be queried as a key on the AttributeSet, with the expectation that a non-null value (of type String) will be present if there was a parameter specification for the property. Reflection is used to set the parameter. Currently, this is limited to a very simple single parameter of type String.

  A simple example HTML invocation is:

            <object classid="javax.swing.JLabel">
            <param name="text" value="sample text">
            </object>
