Eclipse Platform
Release 3.5

org.eclipse.ui.texteditor
Class AbstractTextEditor.LineEndAction

java.lang.Object
  extended by 

org.eclipse.core.commands.common.EventManager
      extended by 

org.eclipse.jface.action.AbstractAction
          extended by 

org.eclipse.jface.action.Action
              extended by 

org.eclipse.ui.texteditor.TextNavigationAction
                  extended by 
org.eclipse.ui.texteditor.AbstractTextEditor.LineEndAction
All Implemented Interfaces:
IAction
Enclosing class:
AbstractTextEditor

protected class AbstractTextEditor.LineEndAction
extends TextNavigationAction

This action implements smart end. Instead of going to the end of a line it does the following: - if smart home/end is enabled and the caret is before the line's last non-whitespace and then the caret is moved directly after it - if the caret is after last non-whitespace the caret is moved at the end of the line - if the caret is at the end of the line the caret is moved directly after the line's last non-whitespace character

Since:
2.1 (in 3.3 the access modifier changed from package visibility to protected)
