%META:TOPICINFO{author="IsaacGouy" date="1075491900" format="1.0" version="1.1"}% %META:TOPICPARENT{name="CodeExamples"}% The BuilderPattern Director is written directly in main; and instead of creating multiple builder classes, we define default multi methods GeneratorMultiMethodExample and specialize them InstanceGeneratorMultiMethodExample and NiceGeneratorMultiMethodExample.

/* Please try the NoviceExamples before the MultiMethodExamples
To compile:
   nicec --sourcepath=.. -a builderpattern.jar builderpattern
To run:
   java -jar builderpattern.jar
