Workflow Pattern - Structured Synchronizin... (2)

• Download

Workflow Pattern - Sequence (1)

• Download

This workflow is a GWorkflowDL representation of a sequence that sequentially invokes A and B. This workflow is equivalent to the following pseudo code: end_A = A(); end_B = B(end_A);

Workflow Pattern - Parallel Split (AND-Split) (1)

• Download

This workflow is a GWorkflowDL representation of a parallel split that invokes A and B recurrently without synchronization. This workflow is equivalent to the following pseudo code: new Thread( end_A = A() ); new Thread( end_B = B() );

Workflow Pattern - Structured Discriminator (2)

• Download

This workflow is a GWorkflowDL representation of a structured discriminator (1-out-of-M Join) that invokes C after the first invocation of A or B (M=2). All next (M-1) invocations of A or B are ignored. This is only one out of various possibilities to model this workflow pattern. Notice alternative representation of this pattern at http://www.myexperiment.org/workflows/632

Workflow Pattern - Cancelling Discriminator (1)

• Download

This workflow is a GWorkflowDL representation of a cancelling discriminator that cancels the invocation of B if A has been executed and vice versa. This is only one out of various possibilities to model this workflow pattern. Please regard that this workflow example uses a separate method for cancelling the invocation of the activity. This is very useful if the invocation of the activity is done asynchronously as it is often implemented for long running methods. It may be necessary to propag...

Workflow Pattern - Structured Partial Join (1)

• Download

This workflow is a GWorkflowDL representation of a structured partial join (N-out-of-M join) that invokes D after N=2 invocations of A or B or C (M=3). All next (M-N) invocations of A or B or C are ignored. This is only one out of various possibilities to model this workflow pattern.

Workflow Pattern - Structured Discriminato... (1)

• Download

This workflow is an alternative GWorkflowDL representation of a structured discriminator (1-out-of-M Join) that invokes C after the first invocation of A or B (M=2). All next (M-1) invocations of A or B are ignored. The pattern is resets if both, A and B have been invoked. Please note that the transitions "C", "ignore", and "release" have different priorities (not shown in the graph) that make the net deterministic (except the occurrence of "A" and &q...

Workflow Pattern - Blocking Discriminator ... (1)

• Download

This workflow is a GWorkflowDL representation of a blocking discriminator (1-out-of-M Join) that invokes C after the first invocation of A or B (M=2). All next (M-1) invocations of A or B are ignored and the AND transition is blocked. The pattern is resets if both, A and B have been invoked. Then the next token on "begin" can be processed. Please note that the transitions "C", "ignore", and "release" have different priorities (represented by p0, p1, an...
