Constructor Detail

FlowBuilderContextImpl

public FlowBuilderContextImpl(java.lang.String flowId,
                              AttributeMap<java.lang.Object> flowAttributes,
                              FlowDefinitionLocator flowDefinitionLocator,
                              FlowBuilderServices flowBuilderServices)

Creates a new flow builder context.

Parameters:

flowId - the id to assign the flow being built

flowAttributes - attributes to assign the flow being built

flowDefinitionLocator - a locator to find dependent subflows

flowBuilderServices - a parameter object providing access to additional services needed by the flow builder

Method Detail

getFlowBuilderServices

public FlowBuilderServices getFlowBuilderServices()

getFlowId

public java.lang.String getFlowId()

Description copied from interface: FlowBuilderContext

Returns an externally configured flow definition identifier to assign to the flow being built.

Specified by:

getFlowId in interface FlowBuilderContext

Returns:

getFlowAttributes

public AttributeMap<java.lang.Object> getFlowAttributes()

Description copied from interface: FlowBuilderContext

Returns externally configured attributes to assign to the flow definition being built.

Specified by:

getFlowAttributes in interface FlowBuilderContext

Returns:

getFlowArtifactFactory

public FlowArtifactFactory getFlowArtifactFactory()

Description copied from interface: FlowBuilderContext

Returns the factory for core flow artifacts such as Flow and State.

Specified by:

getFlowArtifactFactory in interface FlowBuilderContext

Returns:

the flow artifact factory

getFlowDefinitionLocator

public FlowDefinitionLocator getFlowDefinitionLocator()

Description copied from interface: FlowBuilderContext

Returns the locator for locating dependent flows (subflows).

Specified by:

getFlowDefinitionLocator in interface FlowBuilderContext

Returns:

the flow definition locator

getConversionService

public ConversionService getConversionService()

Description copied from interface: FlowBuilderContext

Returns a generic type conversion service for converting between types, typically from string to a rich value object.

Specified by:

getConversionService in interface FlowBuilderContext

Returns:

the generic conversion service

getViewFactoryCreator

public ViewFactoryCreator getViewFactoryCreator()

Description copied from interface: FlowBuilderContext

Returns the view factory creator for configuring a ViewFactory per view state

Specified by:

getViewFactoryCreator in interface FlowBuilderContext

Returns:

the view factory creator

getExpressionParser

public ExpressionParser getExpressionParser()

Description copied from interface: FlowBuilderContext

Returns the expression parser for parsing expression strings.

Specified by:

getExpressionParser in interface FlowBuilderContext

Returns:

the expression parser

getApplicationContext

public org.springframework.context.ApplicationContext getApplicationContext()

Description copied from interface: FlowBuilderContext

Returns the application context hosting the flow system.

Specified by:

getApplicationContext in interface FlowBuilderContext

Returns:

the application context

getValidator

public org.springframework.validation.Validator getValidator()

Description copied from interface: FlowBuilderContext

createConversionService

protected ConversionService createConversionService()

Factory method that creates the conversion service the flow builder will use. Subclasses may override. The default implementation registers Web Flow-specific converters thought to be useful for most builder implementations, setting the externally-provided builder services conversion service as its parent.

Returns:

the flow builder conversion service
