org.kie.internal.command

## Class CommandFactory

- java.lang.Object
- - org.kie.internal.command.CommandFactory

-     public class CommandFactory
      extends Object

  The CommandFactory returns Commands that can be used by classes that implement CommandExecutor. Typically more than one Command will want to be executed, where is where the BatchExecution comes in, which takes a List of commands, think of it as CompositeCommand.

  Out of the box marshalling to XML is support for the Commands, specifically the BatchExecution command and ExecutionResults, using the Drools Pipeline. If the drools-pipeline module is added then the PipelineFactory can be used in conjunction with the BatchExecutionHelper to marshall to and from XML. BatchExecutionHelper also provides additional documentation on the supported XML format.

  `

  This api is experimental and thus the classes and the interfaces returned are subject to change.
