Full quote 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. Next snippet If the primary incoming edge of a DecisionNode is a ControlFlow, then all outgoing edges shall be ControlFlows and, if the primary incoming edge is an ObjectFlow, then all outgoing edges shall be ObjectFlows. 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. Related snippets A DecisionNode is a ControlNode that chooses between outgoing ActivityEdges for the routing of tokens. 15.3.3.6 Decision Nodes - A DecisionNode is a ControlNode that chooses between outgoing flows. Related snippets (backlinks) 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. If a DecisionNode has a decisionInputFlow, then a token must be offered on both the primary incoming edge and the decisionInputFlow before the token from the primary incoming edge is offered to the outgoing edges. If the DecisionNode does not have a decisionInput, then the value contained in the object token on the decisionInputFlow is made available to the guards on each outgoing edge, regardless of whether the primary incoming flow is a ControlFlow or an ObjectFl Visit also Visit also (backlinks) Flags
