org.springframework.webflow.engine.builder.FlowAssembler
A director for assembling flows, delegating to a {@link FlowBuilder} to construct a flow. This class encapsulates thealgorithm 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 = ...; FlowBuilder context = ...; Flow flow = new FlowAssembler(builder, builderContext).assembleFlow(); 
```
