Class Flow

java.lang.Object

javax.faces.flow.Flow

public abstract class Flow
extends Object

Flow is the runtime representation of a Faces Flow. Once placed into service by the runtime, an instance of this class is immutable. The implementation must be thread-safe because instances will be shared across all usages of the flow within the application.

Method Detail

getId

public abstract String getId()

Return the immutable id for this Flow. This must be unique within the defining document (such as an Application Configuration Resources file), but need not be unique within the entire application.

Returns:

the id.

Since:

2.2

getDefiningDocumentId

public abstract String getDefiningDocumentId()

Return the immutable application unique identifier for the document in which the argument flow is defined.

Returns:

the defining document id

Since:

2.2

getStartNodeId

public abstract String getStartNodeId()

Return the immutable id for the default node that should be activated when this flow is entered.

Returns:

the id of the start node

Since:

2.2

getFinalizer

public abstract javax.el.MethodExpression getFinalizer()

Return the MethodExpression that must be called by the runtime as the last thing that happens before exiting this flow. Any FlowScoped beans declared for this flow must remain in scope until after control returns from the method referenced by this MethodExpression.

Returns:

the MethodExpresion for the finalizer.

Since:

2.2

getInitializer

public abstract javax.el.MethodExpression getInitializer()

Return the MethodExpression that must be called by the runtime immediately after activating any FlowScoped beans declared for this flow.

Returns:

the MethodExpresion for the initializer.

Since:

2.2

getInboundParameters

public abstract Map<String,Parameter> getInboundParameters()

Return an immutable data structure containing the inbound parameters that have been declared for this flow. See FlowHandler.transition(javax.faces.context.FacesContext, javax.faces.flow.Flow, javax.faces.flow.Flow, javax.faces.flow.FlowCallNode, java.lang.String) for the specification of how these parameters are used. Inbound parameters are associated with a specific flow instance, while outbound parameters are associated with a FlowCallNode that causes the transition to a new flow.

Returns:

the inbound parameters

Since:

2.2

getViews

public abstract List<ViewNode> getViews()

Return an immutable data structure containing all of the view nodes declared for this flow.

Returns:

the view nodes for this flow

Since:

2.2

getReturns

public abstract Map<String,ReturnNode> getReturns()

Return an immutable data structure containing all of the return nodes declared for this flow.

Returns:

the return nodes for this flow.

Since:

2.2

getSwitches

public abstract Map<String,SwitchNode> getSwitches()

Return an immutable data structure containing all of the switch nodes declared for this flow.

Returns:

the switch nodes for this flow

Since:

2.2

getFlowCalls

public abstract Map<String,FlowCallNode> getFlowCalls()

Return an immutable data structure containing all the flow call nodes declared for this flow.

Returns:

the flow call nodes for this flow

Since:

2.2

getFlowCall

public abstract FlowCallNode getFlowCall(Flow targetFlow)

Return the FlowCallNode that represents calling the targetFlow from this flow, or null if targetFlow cannot be reached from this flow.

Parameters:

targetFlow - the flow for which the FlowCallNode is to be returned

Returns:

a FlowCallNode for the argument flow or null

Since:

2.2

getMethodCalls

public abstract List<MethodCallNode> getMethodCalls()

Return an immutable data structure containing all the method call nodes declared for this flow.

Returns:

the method call nodes for this flow

Since:

2.2

getNode

public abstract FlowNode getNode(String nodeId)

Return the generic FlowNode by id, or null if not found.

Parameters:

nodeId - the node id for which the FlowNode is to be returned

Returns:

the FlowNode or null

getNavigationCases

public abstract Map<String,Set<NavigationCase>> getNavigationCases()

Return an unmodifiable view of the navigation cases within this flow.

Returns:

the navigation cases,

getClientWindowFlowId

public abstract String getClientWindowFlowId(ClientWindow curWindow)

Get the ClientWindow's id and append "_" and the return from getId(). Return the result.

Parameters:

curWindow - the

Returns:

the generated client window id for this flow.

Since:
