## Class SignalHandler

- java.lang.Object
- - org.drools.core.xml.BaseAbstractHandler
  - - org.jbpm.bpmn2.xml.SignalHandler

- All Implemented Interfaces:
    org.drools.core.xml.Handler

      public class SignalHandler
      extends org.drools.core.xml.BaseAbstractHandler
      implements org.drools.core.xml.Handler

  This class isn't currently used because we don't really check thrown or caught event content (itemDefiniton references) to see if it matches the definition in the process. In fact, at this moment, the whole `<signal>` element is ignored because that (specifying event content) is it's only function. This handler is just here for two reasons:
  1. So we can process `<signal>` elements in process definitions
  2. When we do end up actively supporting event content, we'll need the functionality in this class
