Class LookupConnection

java.lang.Object

com.inductiveautomation.ignition.designer.blockandconnector.model.impl.LookupConnection

All Implemented Interfaces:

Connection

public class LookupConnection
extends Object
implements Connection

This implementation of Connection doesn't actually store the AnchorPoint objects themselves, instead, it stores the block ids and anchor point ids. Then it looks these things up on retrieval. This way it is resistant to anchorpoints that get regenerated (for block UIs that are dynamic)
