org.springframework.webflow.definition.registry .ExternalizedFlowDefinitionRegistrar

All known Subclasses:   org.springframework.webflow.engine.builder.xml .XmlFlowRegistrar,
ExternalizedFlowDefinitionRegistrar
abstract public class ExternalizedFlowDefinitionRegistrar implements FlowDefinitionRegistrar(Code)
A flow definition registrar that populates a flow definition registry from flow definitions defined within externalized resources. Encapsulates registration behavior common to all externalized registrars and is not tied to a specific flow definition format (e.g. xml).
Concrete subclasses are expected to derive from this class to provide knowledge about a particular kind of definition format by implementing the abstract template methods in this class.
By default, when configuring the ExternalizedFlowDefinitionRegistrar.setLocations(Resource[]) locations property, flow definitions at those locations will be assigned a registry identifier equal to the filename of the underlying definition resource, minus the filename extension. For example, a XML-based flow definition defined in the file "flow1.xml" will be identified as "flow1" when registered in a registry.
For full control over the assignment of flow identifiers and flow properties, configure formal org.springframework.webflow.definition.registry.FlowDefinitionResource instances using the ExternalizedFlowDefinitionRegistrar.setResources(FlowDefinitionResource[] resources) property.

Method Detail
addLocation
public boolean addLocation(Resource location)(Code)
Adds a flow location pointing to an externalized flow resource.
The flow registered from this location will automatically assigned an id based on the filename of the flow resource.
Parameters:
  location - the definition location

addLocations
public boolean addLocations(Resource[] locations)(Code)
Adds the flow locations pointing to externalized flow resources.
The flow registered from this location will automatically assigned an id based on the filename of the flow resource.
Parameters:
  locations - the definition locations

addResource
public boolean addResource(FlowDefinitionResource resource)(Code)
Adds an externalized flow definition specification pointing to an externalized flow resource.
Use this method when you want full control over the assigned flow id and the set of properties applied to the externalized flow resource.
Parameters:
  resource - the definition the definition resource

addResources
public boolean addResources(FlowDefinitionResource[] resources)(Code)
Adds the externalized flow definitions pointing to externalized flow resources.
Use this method when you want full control over the assigned flow id and the set of properties applied to the externalized flow resources.
Parameters:
  resources - the definitions

createFlowDefinitionHolder
abstract protected FlowDefinitionHolder createFlowDefinitionHolder(FlowDefinitionResource resource)(Code)
Template factory method subclasses must override to return the holder for the flow definition to be registered loaded from the specified resource.
Parameters:
  resource - the externalized resource the flow definition holder

createFlowDefinitionResource
protected FlowDefinitionResource createFlowDefinitionResource(Resource location)(Code)
Factory method that creates a flow definition from an externalized resource location.
Parameters:
  location - the location of the resource the externalized flow definition pointer

isFlowDefinitionResource
protected boolean isFlowDefinitionResource(Resource resource)(Code)
Template method that calculates if the given file resource is actually a flow definition resource. Resources that aren't flow definitions will be ignored. Subclasses may override; this implementation simply returns true.
Parameters:
  resource - the underlying resource true if yes, false otherwise

register
final protected void register(FlowDefinitionResource resource, FlowDefinitionRegistry registry)(Code)
Helper method to register the flow built from an externalized resource in the registry.
Parameters:
  resource - representation of the externalized flow definitionresource
Parameters:
  registry - the flow registry to register the flow in

registerFlowDefinitions
public void registerFlowDefinitions(FlowDefinitionRegistry registry)(Code)

setLocations
public void setLocations(Resource[] locations)(Code)
Sets the locations (file paths) pointing to externalized flow definitions.
Flows registered from this set will be automatically assigned an id based on the filename of the flow resource.
Parameters:
  locations - the resource locations

setResources
public void setResources(FlowDefinitionResource[] resources)(Code)
Sets the formal set of externalized flow definitions this registrar will register.
Use this method when you want full control over the assigned flow id and the set of properties applied to the externalized flow resources.
Parameters:
  resources - the externalized flow definition specifications

toString
public String toString()(Code)
