Examples of org.drools.runtime.process.WorkItem

org.drools.runtime.process.WorkItem
Represents one unit of work that needs to be executed. It contains all the information that it necessary to execute this unit of work as parameters, and (possibly) results related to its execution. WorkItems represent a unit of work in an abstract, high-level and implementation-independent manner. They are created by the engine whenever an external task needs to be performed. The engine will delegate the work item to the appropriate WorkItemHandler for execution. Whenever a work item is completed (or whenever the work item cannot be executed and should be aborted), the work item manager should be notified. For example, a work item could be created whenever an email needs to be sent. This work item would have a name that represents the type of work that needs to be executed (e.g. "Email") and parameters related to its execution (e.g. "From" = "me@mail.com", "To" = ..., "Body" = ..., ...). Result parameters can contain results related to the execution of this work item (e.g. "Success" = true). @see org.drools.runtime.process.WorkItemHandler @see org.drools.runtime.process.WorkItemManager
