| javax.ejb.EntityContext
| EntityContext | | public interface EntityContext extends EJBContext(Code) | | The EntityContext interface provides an instance with access to
the container-provided runtime context of an entity enterprise Bean
instance. The container passes the EntityContext interface to an entity
enterprise Bean instance after the instance has been created.
The EntityContext interface remains associated with the instance for the
lifetime of the instance. Note that the information that the instance
obtains using the EntityContext interface (such as the result of the
getPrimaryKey() method) may change, as the container assigns the instance
to different EJB objects during the instance's life cycle.

| Method Summary | |
| public EJBLocalObject | getEJBLocalObject()
Obtain a reference to the EJB local object that is currently associated with the instance.
An instance of an entity enterprise Bean can call this method only when the instance is associated
with an EJB local object identity, i.e. | | public EJBObject | getEJBObject()
Obtain a reference to the EJB object that is currently associated with the instance.
An instance of an entity enterprise Bean can call this method only when the instance is associated
with an EJB object identity, i.e. | | public Object | getPrimaryKey()
Obtain the primary key of the EJB object that is currently associated with this instance.
An instance of an entity enterprise Bean can call this method only when the instance is associated
with an EJB object identity, i.e. |
| getEJBLocalObject | | public EJBLocalObject getEJBLocalObject() throws IllegalStateException(Code) | | Obtain a reference to the EJB local object that is currently associated with the instance.
An instance of an entity enterprise Bean can call this method only when the instance is associated
with an EJB local object identity, i.e. in the ejbActivate, ejbPassivate, ejbPostCreate, ejbRemove, ejbLoad,
ejbStore, and business methods.
An instance can use this method, for example, when it wants to pass a reference to itself in a
method argument or result.
The EJB local object currently associated with the instance.
exception:
java.lang.IllegalStateException - - if the instance invokes this method while the instanceis in a state that does not allow the instance to invoke this method, or if the instance does not havea local interface. |
| getEJBObject | | public EJBObject getEJBObject() throws IllegalStateException(Code) | | Obtain a reference to the EJB object that is currently associated with the instance.
An instance of an entity enterprise Bean can call this method only when the instance is associated
with an EJB object identity, i.e. in the ejbActivate, ejbPassivate, ejbPostCreate, ejbRemove, ejbLoad,
ejbStore, and business methods.
An instance can use this method, for example, when it wants to pass a reference to itself in a method
argument or result.
The EJB object currently associated with the instance.
exception:
java.lang.IllegalStateException - - Thrown if the instance invokes this method while the instanceis in a state that does not allow the instance to invoke this method, or if the instance does not have aremote interface. |
| getPrimaryKey | | public Object getPrimaryKey() throws IllegalStateException(Code) | | Obtain the primary key of the EJB object that is currently associated with this instance.
An instance of an entity enterprise Bean can call this method only when the instance is associated
with an EJB object identity, i.e. in the ejbActivate, ejbPassivate, ejbPostCreate, ejbRemove, ejbLoad,
ejbStore, and business methods.
Note: The result of this method is that same as the result of getEJBObject().getPrimaryKey().
The primary key currently associated with the instance.
exception:
java.lang.IllegalStateException - - Thrown if the instance invokes this method while theinstance is in a state that does not allow the instance to invoke this method. |
