Message Flow

A Message Flow represents the communication of messages between two participants.

• Pools, Activities and Events can be the source and target of message flows.

• Message Flows must connect to the Pool boundary or to flow objects within the Pool. They can’t connect elements within the same pool.

• They connect either to the boundary of a Pool or directly to flow elements inside the Pool.

Message Flow appears as a dashed line with an open circle at the start of the line and a clear arrowhead.
