  • A person may play the role of several different actors and, conversely, a given actor may be played by multiple different person.

Lifeline

  • A lifeline represents an individual participant in the Interaction.

Activations

  • A thin rectangle on a lifeline) represents the period during which an element is performing an operation.
  • The top and the bottom of the of the rectangle are aligned with the initiation and the completion time respectively

Call Message

  • A message defines a particular communication between Lifelines of an Interaction.
  • Call message is a kind of message that represents an invocation of operation of target lifeline.

Return Message

  • A message defines a particular communication between Lifelines of an Interaction.
  • Return message is a kind of message that represents the pass of information back to the caller of a corresponded former message.

Self Message

  • A message defines a particular communication between Lifelines of an Interaction.
  • Self message is a kind of message that represents the invocation of message of the same lifeline.

Recursive Message

  • A message defines a particular communication between Lifelines of an Interaction.
  • Recursive message is a kind of message that represents the invocation of message of the same lifeline. It's target points to an activation on top of the activation where the message was invoked from.

Create Message

  • A message defines a particular communication between Lifelines of an Interaction.
  • Create message is a kind of message that represents the instantiation of (target) lifeline.

Destroy Message

  • A message defines a particular communication between Lifelines of an Interaction.
  • Destroy message is a kind of message that represents the request of destroying the lifecycle of target lifeline.

Duration Message

  • A message defines a particular communication between Lifelines of an Interaction.
  • Duration message shows the distance between two time instants for a message invocation.

Note

A note (comment) gives the ability to attach various remarks to elements. A comment carries no semantic force, but may contain information that is useful to a modeler.
