Interface Terminal

All Superinterfaces:

CanvasComponent, Figure, UserObjectContainer, VisibleComponent

All Known Implementing Classes:

StraightTerminal, TerminalFigure

public interface Terminal
extends Figure

A Terminal is a figure that provides a visible place for connectors to connect to. In general, connectors are able to connect to anything, but in certain types of diagrams, such as circuit schematics, connectors are expected to connect to objects that are clearly identifiable as a "connection point." Terminals serve this purpose.

The terminal interface exposes access to two sites: The "attach" site is the site on some other figure that the terminal positions itself on, and the "connect" site is the site that connectors can connect to.
