Constructor Detail

FlowParser

public FlowParser(String flowName,
                  String jobFactoryRef)

Construct a FlowParser with the specified name and using the provided job repository ref.

Parameters:

flowName - the name of the flow

jobFactoryRef - the reference to the JobParserJobFactoryBean from the enclosing tag

Method Detail

getBeanClass

protected Class<SimpleFlow> getBeanClass(Element element)

Overrides:

getBeanClass in class AbstractSingleBeanDefinitionParser

doParse

protected void doParse(Element element,
                       ParserContext parserContext,
                       BeanDefinitionBuilder builder)

Overrides:

doParse in class AbstractSingleBeanDefinitionParser

Parameters:

element - the top level element containing a flow definition

parserContext - the ParserContext

getNextElements

protected static Collection<BeanDefinition> getNextElements(ParserContext parserContext,
                                                            BeanDefinition stateDef,
                                                            Element element)

Parameters:

parserContext - the parser context for the bean factory

stateDef - The bean definition for the current state

element - the <step/gt; element to parse

Returns:

a collection of StateTransition references

getNextElements

protected static Collection<BeanDefinition> getNextElements(ParserContext parserContext,
                                                            String stepId,
