1.如何在系统中查找对象对应的类

打开站点中的"类型和属性管理器",选择部件,这个部件就对应了系统中的一个对象,wt.part.WTPart就是系统中部件对应的类,wt.part是包名,WTPart就是类的名称

2.系统类的设计

系统中的服务类设计为xxHelper.java文件和xxService.java是组合关系，系统中的所有业务对象对应的方法在对应的service中，通过xxHelper.serivce.方法  .

部件操作：WTPartHelper.service.方法
文档操作：WTDocumentHelper.service.方法
EC操作：ChangeHelper2.service.方法
文件夹的操作：FolderHelper.service.方法
生命周期的操作：LifeCycleHelper.manager.方法
推进流程对象的操作：MaturityHelper.service.方法
通知机制对象的操作：NotificationHelper.service.方法
位号的操作：OccurrenceHelper.service.方法
参与者的操作：OrganizationServicesHelper.manager.方法
版本的操作：VersionControlHelper.service.方法

3.如何通过类在数据库中查找相关的表
在类型管理器中定义的那些对象在数据库中都有对应的表存在.如部件对象的类名是WTPart.
如要获取一个部件的生命周期状态,数据库中对应字段是statestate这个字段,那么在代码中通过part.getLifeCycleState().getDisplay()这个函数来获取.

 

4.类型
类型的值被定义在 wt.doc.DocumentTypeRB中
Department
在Windchill中允许用户选择区域，负责文件的管理,值都被定义在 wt.doc.DepartmentListRB中

文件与文件之间的关系:
文件结构 ： 一个文件可以使用很多其它子文件，其下层子文件也可以被其它文件使用。(使用与被使用的关系)
文件参考 ：一个文件涉及的信息存在于其他文件中。(参考与被参考的关系)

部件wt.part.WTPart
部件参考wt.part.WTPartReferenceLink
部件主数据wt.part.WTPartMaster
文档wt.doc.WTDocument
文档使用wt.doc.WTDocumentUsageLink
文档主数据wt.doc.WTDocumentMaster
项目wt.projmgmt.admin.Project2
项目活动 (典型)wt.projmgmt.execution.ProjectActivity
用户wt.org.WTUser
产品wt.pdmlink.PDMLinkProduct
存储库wt.inf.library.WTLibrary
活动com.ptc.projectmanagement.plan.PlanActivity
计划com.ptc.projectmanagement.plan.Plan
交付com.ptc.windchill.wp.delivery.DeliveryRecord
角色承担者wt.org.WTRolePrincipal
进程com.ptc.windchill.dpimpl.core.WTMasterProcess
可交付结果com.ptc.projectmanagement.deliverable.PlanDeliverable

5.Windchill各个包的介绍 

Package	Functionality
access	Functionality for access control; used to define access policies and object ownership (that is, define rules for what users or groups have access to what information).
admin	Functionality to create administrative domains and policies.
change2	Functionality to manipulate change items (change issue, request, investigation, proposal, order, and change activity).
container.batch	Functionality for a client application to gather a group of create, modify, and delete assertions, and submit them to a service method for processing in one transaction.
content	Functionality for handling content data (attaching files and URLs to content holders, such as documents and change objects) and associating business information metadata (such as the author) with content.
doc	Functionality for document management.
effectivity	Functionality to assert that a PDM object is effective under certain conditions.
enterprise	Functionality for the basic business objects used in the Windchill system.
events	Functionality for registration, subscription and notification of processing events. The events package provides a hierarchical subscription mechanism that makes it possible to subscribe directly to events of interest. Event dispatching is based on simple synchronous in-thread/transaction calls.
fc	Basic foundation classes (WTObject, Item, and Link) and basic services for those classes (persistence, object mappable, and identify service).
federation	The federation service provides functionality to create and manage proxy objects of remote systems and perform utility functions supporting the federation system.
folder	Functionality to put information into folders and cabinets for navigational purposes.
fv	Functionality to define and execute the vaulting algorithm for content items.
identity	Functionality to display the identity of business objects; that is, their type and identifier (for example, a type of part and an identifier of part number).
index	Functionality to index metadata and content data, controlling how information is put into search indexes.
introspection	Functionality to make model information available to a run time system. This includes class hierarchy, association, attribute, and database mapping information.
lifecycle	Functionality to define and use life cycles.
locks	Functionality to lock and unlock objects.
notify	Functionality to define rules such that when certain events occur to certain objects, E-mail notification is sent.
org	Organization services; functionality to create users and groups (generically called principals).
ownership	Functionality to define ownership of an objects.
part	Functionality to manipulate parts.
project	Functionality to create projects, associate projects to business objects, and resolve roles to principals.
query	Functionality to create queries for retrieving persistent objects.
queue	Functionality to define and manage queues. Queues are used to persistently record deferred processes. Because queued processes are persistently stored, they are guaranteed to execute at a later time.
router	Functionality to distribute execution of tasks to multiple Windchill method servers.
scheduler	Functionality to schedule execution of resource intensive method invocations and keep a history of their outcomes.
services	Functionality to define and manage application services. Service management includes service start up and shutdown along with service event registration, subscription and notification.
session	Functionality to define and manage user sessions.
util	The util package groups together simple low level utilities that do not belong in other packages.
vc	Version control; functionality to handle versions of objects. Version control services described in this chapter include baselines, configuration specifications, version structuring, version viewing, and work in progress.
workflow	Functionality to create and manage workflow definitions, initiate and manage process instances, and distribute work items to users and groups.
