# 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>
