org.camunda.bpm.engine.impl.bpmn.deployer.BpmnDeployer

All Implemented Interfaces:

Deployer

public class BpmnDeployer
extends AbstractDefinitionDeployer<ProcessDefinitionEntity>

Deployer responsible to parse BPMN 2.0 XML files and create the proper ProcessDefinitionEntitys. Overwrite this class if you want to gain some control over this mechanism, e.g. setting different version numbers, or you want to use your own BpmnParser.
