## org.jbpm.executor.impl.wih
Class AsyncWorkItemHandler

    java.lang.Object
      org.jbpm.executor.impl.wih.AsyncWorkItemHandler

All Implemented Interfaces:
  WorkItemHandler

    public class AsyncWorkItemHandler

extends Object
implements WorkItemHandler

Asynchronous work item handler that utilizes power of `ExecutorService`. it expects following parameters to be present on work item for proper execution:

- CommandClass - FQCN of the command to be executed - mandatory unless this handler is configured with default command class
- Retries - number of retires for the command execution - optional

During execution it will set contextual data that will be available inside the command:

- businessKey - generated from process instance id and work item id in following format: [processInstanceId]:[workItemId]
- workItem - actual work item instance that is being executed (including all parameters)
- processInstanceId - id of the process instance that triggered this work item execution

In case work item shall be aborted handler will attempt to cancel active requests based on business key (process instance id and work item id)
