Tests whether adding a connection between the given source and target plugs will create an invalid cycle.

The unit classifier.The board classifier.The source plug classifier.The target plug classifier.The target parent classifier.The source parent classifier.Indicates whether the candidate connection creates an invalid cyclic connection.<h2>Dependencies</h2><table class="WHITE" style="width:auto; margin-top:0" cellspacing="1"><tr><td class="H V"><i>pre-condition:</i> </td><td class=H><q ref="core.gml2:canConnectFrom">canConnectFrom</q> == true </td></tr><tr><td class=V><i>pre-condition:</i> </td><td><q ref="core.gml2:canConnectTo">canConnectTo</q> == true </td></tr></table> <h2>Behavior</h2> Use this rule to test for and prevent invalid cyclic connections. The behavior should be to look for cyclic connections that may be created if the given source and target plugs are connected. Whether such cyclic connections (if found) are allowed depends on the type of elements that are connected. By default, all cyclic connections are allowed.(c) SAP AG 2003-2006. All rights reserved.
