If the DecisionNode has only one incoming edge, then it is the primary incoming edge. Full quote A DecisionNode accepts tokens on its primary incoming edge and offers them to all its outgoing edges. However, each token offered on the primary incoming edge shall traverse at most one outgoing edge. Tokens are not duplicated. Next snippet Related snippets A DecisionNode is a ControlNode that chooses between outgoing ActivityEdges for the routing of tokens. DecisionNode::edges The ActivityEdges incoming to and outgoing from a DecisionNode, other than the decisionInputFlow (if any), must be either all ObjectFlows or all ControlFlows. 15.3.3.6 Decision Nodes - A DecisionNode is a ControlNode that chooses between outgoing flows. A DecisionNode shall have at least one and at most two incoming ActivityEdges, and at least one outgoing ActivityEdge. If it has two incoming edges, then one shall be identified as the decisionInputFlow, the other being called the primary incoming edge. If the DecisionNode has only one incoming edge, then it is the primary incoming edge. Related snippets (backlinks) Visit also Visit also (backlinks) Flags
