## Class KillRing

- java.lang.Object
- - org.gjt.sp.jedit.buffer.KillRing

- All Implemented Interfaces:
    javax.swing.ListModel, MutableListModel

      public class KillRing
      extends java.lang.Object
      implements MutableListModel

  The kill ring retains deleted text. This class is a singleton -- only one kill ring is used for all of jEdit. Nothing prevents plugins from making their own kill rings for whatever reason, though.

  - ### Method Detail

    - #### getInstance

          public static KillRing getInstance()

    - #### setInstance

          public static void setInstance(KillRing killRing)

    - #### propertiesChanged

          public void propertiesChanged(int historySize)

    - #### load

          public void load()

    - #### save

          public void save()

    - #### reset

          protected void reset(java.util.Collection<?> source)

      This method is made to be used by implementation of load() method to initialize (or reset) the killring by a loaded sequence of objects. Each element is converted to an element of the killring as followings: - If it is a String, it is converted as if it is a result of getElementAt(n).toString(). - Otherwise, it is converted as if it is a Object which was obtained by getElementAt(n).
      Parameters:
        `source` - the loaded killring.
