  +--audiojury.action.ProjectBuilder

public class ProjectBuilder

extends java.lang.Object

Does simple operations on a dynamic Project.
The class implements the Singleton design pattern, which means there is only one instance of this class. This is necessary to make concurrent access to projects impossible. The ProjectBuilder only operates on one project at a time.

Method Summary

Project	getCurrentProject() Returns the Project currently being built upon.
static ProjectBuilder	getUniqueInstance() Enforces the Singleton design pattern by always returning the same instance of ProjectBuilder.
void	setCurrentProject(Project project) Sets which Project to make as current.
void	setInstructions(Instruction inst) Assigns Instruction to the current project.
void	setPersItems(java.lang.String[] items) Assigns which personal attributes to collect.
