Class SimpleFlowFactoryBean

java.lang.Object

org.springframework.batch.core.configuration.xml.SimpleFlowFactoryBean

All Implemented Interfaces:

org.springframework.beans.factory.FactoryBean<SimpleFlow>, org.springframework.beans.factory.InitializingBean

Direct Known Subclasses:

JsrFlowFactoryBean

public class SimpleFlowFactoryBean
extends java.lang.Object
implements org.springframework.beans.factory.FactoryBean<SimpleFlow>, org.springframework.beans.factory.InitializingBean

Convenience factory for SimpleFlow instances for use in XML namespace. It replaces the states in the input with proxies that have a unique name formed from the flow name and the original state name (unless the name is already in that form, in which case it is not modified).

Constructor Detail

SimpleFlowFactoryBean

public SimpleFlowFactoryBean()

Method Detail

setStateTransitionComparator

public void setStateTransitionComparator(java.util.Comparator<StateTransition> stateTransitionComparator)

Parameters:

stateTransitionComparator - Comparator implementation that addresses the ordering of state evaluation

setFlowType

public void setFlowType(java.lang.Class<SimpleFlow> flowType)

Parameters:

flowType - Used to inject the type of flow (regular Spring Batch or JSR-352)

setName

public void setName(java.lang.String name)

The name of the flow that is created by this factory.

Parameters:

name - the value of the name

setStateTransitions

public void setStateTransitions(java.util.List<StateTransition> stateTransitions)

The raw state transitions for the flow. They will be transformed into proxies that have the same behavior but unique names prefixed with the flow name.

Parameters:

stateTransitions - the list of transitions

afterPropertiesSet

public void afterPropertiesSet()
                        throws java.lang.Exception

Check mandatory properties (name).

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

Throws:

java.lang.Exception

getObject

public SimpleFlow getObject()
                     throws java.lang.Exception

Specified by:

getObject in interface org.springframework.beans.factory.FactoryBean<SimpleFlow>

Throws:

java.lang.Exception

createNewStepState

protected State createNewStepState(State state,
                                   java.lang.String oldName,
                                   java.lang.String stateName)

Provides an extension point to provide alternative StepState implementations within a SimpleFlow

Parameters:

state - The state that will be used to create the StepState

oldName - The name to be replaced

stateName - The name for the new State

Returns:

getObjectType

public java.lang.Class<?> getObjectType()

Specified by:

getObjectType in interface org.springframework.beans.factory.FactoryBean<SimpleFlow>

isSingleton

public boolean isSingleton()

Specified by:

isSingleton in interface org.springframework.beans.factory.FactoryBean<SimpleFlow>
