 org.springframework.webflow.engine.builder.FlowAssembler
| FlowAssembler | | public class FlowAssembler (Code) | | A director for assembling flows, delegating to a
FlowBuilder to
construct a flow. This class encapsulates the algorithm for using a
FlowBuilder to assemble a Flow properly. It acts as the director in the
classic GoF builder pattern.
Flow assemblers may be used in a standalone, programmatic fashion as follows:
FlowBuilder builder = ...;
Flow flow = new FlowAssembler("myFlow", builder).assembleFlow();

| Constructor Summary | |
| public | FlowAssembler(String flowId, FlowBuilder flowBuilder)
Create a new flow assembler that will direct Flow assembly using the
specified builder strategy. | | public | FlowAssembler(String flowId, AttributeMap flowAttributes, FlowBuilder flowBuilder)
Create a new flow assembler that will direct Flow assembly using the
specified builder strategy. |
| Method Summary | |
| public Flow | assembleFlow()
Assembles the flow, directing the construction process by delegating to
the configured FlowBuilder. | | protected void | directAssembly()
Build all parts of the flow by directing flow assembly by the flow
builder. | | public AttributeMap | getFlowAttributes()
Returns externally assigned attributes that can be used to affect flow
construction. | | public FlowBuilder | getFlowBuilder()
Returns the flow builder strategy used to construct the flow from its
component parts. | | public String | getFlowId()
Returns the identifier to assign to the flow. |
