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)
