- All Implemented Interfaces:
    org.springframework.beans.factory.xml.BeanDefinitionParser

      public class FlowParser
      extends AbstractFlowParser

  Parses flows as defined in JSR-352. The current state parses a flow as it is within a regular Spring Batch job/flow.

      Parameters:
        `status` - The batch status that this transition will set. Use BatchStatus.UNKNOWN if not applicable.
        `on` - The pattern that this transition should match. Use null for "no restriction" (same as "*").
        `next` - The state to which this transition should go. Use null if not applicable.
        `exitCode` - The exit code that this transition will set. Use null to default to batchStatus.
        `stateDef` - The bean definition for the current state
        `parserContext` - the parser context for the bean factory
      Returns:
        a collection of `StateTransition` references
