Class SplitScreenImpl

java.lang.Object
org.aesh.terminal.tty.split.SplitScreenImpl
All Implemented Interfaces:
org.aesh.terminal.tty.SplitScreen
public class SplitScreenImpl extends Object implements org.aesh.terminal.tty.SplitScreen
Implementation of split-screen using cursor addressing.

The terminal is divided into a top region (for output/logs) and a bottom region (for readline). A separator line is drawn between them. Each region has its own scrollback buffer. Rendering uses cursor save/restore and absolute cursor positioning (ESC [row;colH).

Experimental — this feature is under active development.
