Package Summary Overview Summary

### class:JSeparator [NONE]
- All Implemented Interfaces: ImageObserver, MenuContainer, Serializable, Accessible, SwingConstants Direct Known Subclasses: JPopupMenu.Separator, JToolBar.Separator
      public class JSeparator
      extends JComponent
      implements SwingConstants, Accessible
`JSeparator` provides a general purpose component for implementing divider lines - most commonly used as a divider between menu items that breaks them up into logical groupings. Instead of using `JSeparator` directly, you can use the `JMenu` or `JPopupMenu` `addSeparator` method to create and add a separator. `JSeparator`s may also be used elsewhere in a GUI wherever a visual divider is useful. For more information and examples see How to Use Menus , a section in The Java Tutorial. Warning: Swing is not thread safe. For more information see Swing's Threading Policy . Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the `java.beans` package. Please see `XMLEncoder`. Since: 1.2

### constructor:JSeparator() [NONE]

Creates a new horizontal separator.

### constructor:JSeparator(int) [NONE]
- #### JSeparator
      public JSeparator(int orientation)
Creates a new separator with the specified horizontal or vertical orientation. Parameters: `orientation` - an integer specifying `SwingConstants.HORIZONTAL` or `SwingConstants.VERTICAL` Throws: `IllegalArgumentException` - if `orientation` is neither `SwingConstants.HORIZONTAL` nor `SwingConstants.VERTICAL`

### method:getUI() [NONE]
- #### getUI
      public SeparatorUI getUI()
Returns the L&F object that renders this component. Returns: the SeparatorUI object that renders this component

### method:setUI(javax.swing.plaf.SeparatorUI) [NONE]
- #### setUI
      public void setUI(SeparatorUI ui)
Sets the L&F object that renders this component. Parameters: `ui` - the SeparatorUI L&F object See Also: `UIDefaults.getUI(javax.swing.JComponent)`

### method:updateUI() [NONE]
- #### updateUI
      public void updateUI()
Resets the UI property to a value from the current look and feel. Overrides: `updateUI` in class `JComponent` See Also: `JComponent.updateUI()`

### method:getUIClassID() [NONE]
- #### getUIClassID
      public String getUIClassID()
Returns the name of the L&F class that renders this component. Overrides: `getUIClassID` in class `JComponent` Returns: the string "SeparatorUI" See Also: `JComponent.getUIClassID()`, `UIDefaults.getUI(javax.swing.JComponent)`

### method:getOrientation() [NONE]
- #### getOrientation
      public int getOrientation()
Returns the orientation of this separator. Returns: The value of the orientation property, one of the following constants defined in `SwingConstants`: `VERTICAL`, or `HORIZONTAL`. See Also: `SwingConstants`, `setOrientation(int)`

### method:setOrientation(int) [NONE]
- #### setOrientation
      public void setOrientation(int orientation)
Sets the orientation of the separator. The default value of this property is HORIZONTAL. Parameters: `orientation` - either `SwingConstants.HORIZONTAL` or `SwingConstants.VERTICAL` Throws: `IllegalArgumentException` - if `orientation` is neither `SwingConstants.HORIZONTAL` nor `SwingConstants.VERTICAL` See Also: `SwingConstants`, `getOrientation()`

### method:paramString() [NONE]
- #### paramString
      protected String paramString()
Returns a string representation of this `JSeparator`. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be `null`. Overrides: `paramString` in class `JComponent` Returns: a string representation of this `JSeparator`

### method:getAccessibleContext() [NONE]
- #### getAccessibleContext
      public AccessibleContext getAccessibleContext()
Gets the AccessibleContext associated with this JSeparator. For separators, the AccessibleContext takes the form of an AccessibleJSeparator. A new AccessibleJSeparator instance is created if necessary. Specified by: `getAccessibleContext` in interface `Accessible` Overrides: `getAccessibleContext` in class `Component` Returns: an AccessibleJSeparator that serves as the AccessibleContext of this JSeparator
