Interface EJBLocalObjectpublic interface EJBLocalObjectThe EJBLocalObject interface must be extended by all enterprise Beans' local interfaces. An enterprise Bean's local interface provides the local client view of an EJB object. An enterprise Bean's local interface defines the business methods callable by local clients. 所有企业Bean的本地接口均继承EJBLocalObject接口。企业Bean的本地接口提供EJB对象的本地客户端视图。企业Bean的本地接口定义了本地客户端可调用的业务方法。
The enterprise Bean's local interface is defined by the enterprise Bean provider and implemented by the enterprise Bean container. 企业Bean的本地接口由企业Bean提供者定义,由企业Bean容器实现。
Method Summary
Obtain the enterprise Bean's local home interface. 获得企业Bean的本地home接口。
Obtain the primary key of the EJB local object. 获得EJB本地对象的主键。
boolean
isIdentical(EJBLocalObject obj)
Test if a given EJB local object is identical to the invoked EJB local object. 测试指定的EJB本地对象是否和调用的EJB本地对象为同一对象。
void
remove()
Remove the EJB local object. 删除EJB本地对象。
Method Detail
getEJBLocalHomepublic EJBLocalHome getEJBLocalHome()
throws EJBException
Obtain the enterprise Bean's local home interface. The local home interface defines the enterprise Bean's create, finder, remove, and home business methods that are available to local clients. 获得企业Bean的本地home接口。本地home接口定义本地客户端可用的企业Bean的create、finder、remove和home业务方法。
Returns: A reference to the enterprise Bean's local home interface. 企业Bean的本地home接口引用。 Throws: EJBException - Thrown when the method failed due to a system-level failure. 方法抛出该异常表示一个由系统级错误引起的失败。getPrimaryKeypublic Object getPrimaryKey()
throws EJBException
Obtain the primary key of the EJB local object. 获得EJB本地对象的主键。 This method can be called on an entity bean. An attempt to invoke this method on a session Bean will result in an EJBException. 实体bean可以调用该方法。会话bean试图调用该方法会造成RemoteException。
Returns: The EJB local object's primary key. EJB对象的主键。 Throws: EJBException - Thrown when the method failed due to a system-level failure or when invoked on a session bean. 方法抛出该异常表示一个由系统级错误或者因为会话bean调用引起的失败。removepublic void remove()
throws RemoveException,
Remove the EJB local object. 删除EJB对象。
Throws: RemoveException - The enterprise Bean or the container does not allow destruction of the object. 企业Bean或容器不允许清除该对象时抛出。 EJBException - Thrown when the method failed due to a system-level failure. 方法抛出该异常表示一个由系统级错误引起的失败。isIdenticalpublic boolean isIdentical(EJBLocalObject obj)
throws EJBException
Test if a given EJB local object is identical to the invoked EJB local object. 测试指定的EJB本地对象是否和调用的EJB本地对象为同一对象。
Parameters: obj - An object to test for identity with the invoked object. 与调用对象比较是否相同的对象。 Returns: True if the given EJB local object is identical to the invoked object, false otherwise. 如果指定的EJB本地对象和调用对象相同,返回true,否则为false。 Throws: EJBException - Thrown when the method failed due to a system-level failure. 方法抛出该异常表示一个由系统级错误引起的失败。[/url][url=file:///F:/资料/文字资料/j2ee-1.4_doc/apidocs/overview-summary.html]Overview
