Method Detail

setJobFactoryRef

protected void setJobFactoryRef(String jobFactoryRef)

Convenience method for subclasses to set the job factory reference if it is available (null is fine, but the quality of error reports is better if it is available).

Parameters:

jobFactoryRef -

getBeanClass

protected Class<?> 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,
                                                            BeanDefinition stateDef,
                                                            Element element)

Parameters:

parserContext - the parser context for the bean factory

stepId - the id of the current state if it is a step state, null otherwise

stateDef - The bean definition for the current state

element - the <step/gt; element to parse

Returns:

a collection of StateTransition references

getStateTransitionReference

public static BeanDefinition getStateTransitionReference(ParserContext parserContext,
                                                         BeanDefinition stateDefinition,
                                                         String on,
