Issue 6364: Decision behaviors on control tokens (uml2-superstructure-ftf)
Source: NIST (Dr. Conrad Bock, conrad.bock(at)nist.gov)
Nature: Revision
Severity: 
Summary: Clarify that decision behaviors work on control tokens.  Suggest that
control tokens invoke behaviors with no input parameters.  Behavior can
use ReadSelfAction to access host if necessary
Resolution: see above
Revised Text: 
Actions taken:
October 20, 2003: received issue
March 8, 2005: closed issue
Discussion: 
In Constraint section of Decision Node, p 320, change the first two sentences of
constraint [2] to:
"A decision input behavior has zero or one input parameter and one output
parameter. Any input parameter must be the same as or a supertype of the type
of object tokens coming along the incoming edge."
In the Semantics section of Decision Node, p 320, last paragraph, change the first
sentence to:
"If a decision input behavior is specified, then each data token is passed to the
behavior before guards are evaluated on the outgoing edges. The behavior is
invoked without input for control tokens."
