Defi nition
An allocate activity partition is a special activity partition that allocates each
action within that partition to the structure that represents this partition.
It is a stereotype ?«allocateActivityPartition?» of the UML element activity
partition.
An activity partition puts actions into groups based on common features. The
allocate activity partition restricts the grouping criteria. The common features
of actions within an allocate activity partition form a block to which these actions
are allocated. This means that an action is the target element (the from end) of
an allocation relationship, while the structure is the source element (the to end).
