Cancelation patterns are a set of patterns that deal with the cancellation of case, activity, task, subprocess, and so on. We will just list the pattern features; however, we will find various occurrences in this book where cancelation patterns are used. We will include a reference to those sections where that specific cancelation pattern is implemented or demonstrated. There are various variants of cancelation patterns such as cancel case, cancel task, cancel activity, cancel multi-instance subprocess, complete multi-instance subprocess, and so on. Cancel case pattern is covered in Chapter 8, Adaptive Case Management. Cancel task pattern is covered in Chapter 4, Human Task Patterns. Chapter 6, Correlation Patterns, contains the implementation of trigger patterns in the Cancel activity pattern section.
