Full quote A MergeNode shall have exactly one outgoing ActivityEdge but may have multiple incoming ActivityEdges. Next snippet If the outgoing edge of a MergeNode is a ControlFlow, then all incoming edges must be ControlFlows, and, if the outgoing edge is an ObjectFlow, then all incoming edges must be ObjectFlows. Related snippets A MergeNode is a control node that brings together multiple flows without synchronization. A DecisionNode is a ControlNode that chooses between outgoing ActivityEdges for the routing of tokens. Related snippets (backlinks) If the outgoing edge of a MergeNode is a ControlFlow, then all incoming edges must be ControlFlows, and, if the outgoing edge is an ObjectFlow, then all incoming edges must be ObjectFlows. All tokens offered on the incoming edges of a MergeNode are offered to the outgoing edge. There is no synchronization of flows or joining of tokens. Visit also Visit also (backlinks) Flags
