org.springframework.webflow.config .FlowExecutorFactoryBean

FlowExecutorFactoryBean

public class FlowExecutorFactoryBean implements FactoryBean,InitializingBean(Code)

The default flow executor factory implementation. As a FactoryBean, this class has been designed for use as a Spring managed bean.

This factory encapsulates the construction and assembly of a FlowExecutor , including the provision of its FlowExecutionRepository strategy.

The FlowExecutorFactoryBean.setDefinitionLocator(FlowDefinitionLocator) definition locator property is required, all other properties are optional.

This class has been designed with subclassing in mind. If you want to do advanced Spring Web Flow customization, e.g. using a custom org.springframework.webflow.executor.FlowExecutor implementation, consider subclassing this class and overriding one or more of the provided hook methods.

Parameters: repositoryType - a hint indicating what type of repository to create Parameters: executionStateRestorer - the execution state restorer strategy to be used bythe repository Parameters: conversationManager - the conversation manager specified by the user,could be null in which case the default conversation manager should be used a new flow execution repository instance

createFlowExecutionFactory
protected FlowExecutionFactory createFlowExecutionFactory(AttributeMap executionAttributes, FlowExecutionListenerLoader executionListenerLoader)(Code)
	Create the flow execution factory to be used by the executor produced by this factory bean. Configure the execution factory appropriately. Subclasses may override if they which to use a custom execution factory, e.g. to use a custom FlowExecution implementation. Parameters: executionAttributes - execution attributes to apply to created executions Parameters: executionListenerLoader - decides which listeners to apply to created executions a new flow execution factory instance

createFlowExecutionStateRestorer
protected FlowExecutionStateRestorer createFlowExecutionStateRestorer(FlowDefinitionLocator definitionLocator, AttributeMap executionAttributes, FlowExecutionListenerLoader executionListenerLoader)(Code)
	Create the flow execution state restorer to be used by the executor produced by this factory bean. Configure the state restorer appropriately. Subclasses may override if they which to use a custom state restorer implementation. Parameters: definitionLocator - the definition locator to use Parameters: executionAttributes - execution attributes to apply to restored executions Parameters: executionListenerLoader - decides which listeners should apply to restoredflow executions a new state restorer instance

createFlowExecutor
protected FlowExecutor createFlowExecutor(FlowDefinitionLocator definitionLocator, FlowExecutionFactory executionFactory, FlowExecutionRepository executionRepository)(Code)
	Create the flow executor instance created by this factory bean and configure it appropriately. Subclasses may override if they which to use a custom executor implementation. Parameters: definitionLocator - the definition locator to use Parameters: executionFactory - the execution factory to use Parameters: executionRepository - the execution repository to use a new flow executor instance

getFlowExecutor
public FlowExecutor getFlowExecutor()(Code)
	Returns the flow executor constructed by the factory bean. since: 1.0.2

getInputMapper
protected AttributeMapper getInputMapper()(Code)
	Return the configured input mapper.

getMaxContinuations
protected Integer getMaxContinuations()(Code)
	Returns the configured maximum number of continuation snapshots allowed for a single conversation when using the RepositoryType.CONTINUATION continuation flow execution repository. the configured value or null if the user did not explicitlyspecify a value and wants to use the default since: 1.0.1

setConversationManager

public void setConversationManager(ConversationManager conversationManager)(Code)

Sets the strategy for managing conversations that should be configured for flow executors created by this factory.

The conversation manager is used by the flow execution repository subsystem to begin and end new conversations that store execution state.

setDefaults
public void setDefaults(FlowSystemDefaults defaults)(Code)
	Set system defaults that should be used. Parameters: defaults - the defaults to use.

public void setDefinitionLocator(FlowDefinitionLocator definitionLocator)(Code)
	Sets the flow definition locator that will locate flow definitions needed for execution. Typically also a FlowDefinitionRegistry . Required. Parameters: definitionLocator - the flow definition locator (registry)

setExecutionAttributes
public void setExecutionAttributes(Map executionAttributes)(Code)
	Sets the system attributes that apply to flow executions launched by the executor created by this factory. Execution attributes may affect flow execution behavior. Note: this method simply accepts a generic `java.util.Map` to allow for easy configuration by Spring. The map entries should consist of non-null String keys with object values. Parameters: executionAttributes - the flow execution system attributes
