Examples of org.apache.commons.scxml.model.Parallel

org.apache.commons.scxml.model.Parallel
The class in this SCXML object model that corresponds to the <parallel> SCXML element, which is a wrapper element to encapsulate parallel state machines. For the <parallel> element to be useful, each of its <state> substates must itself be complex, that is, one with either <state> or <parallel> children.
