| 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 | |
| EJBLocalObject | getEJBLocalObject()
Obtain a reference to the EJB local object that is currently
associated with the instance. | | EJBObject | getEJBObject()
Obtain a reference to the EJB object that is currently associated with
the instance. | | Object | getPrimaryKey()
Obtain the primary key of the EJB object that is currently
associated with this instance. |
| getEJBLocalObject | | 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:
IllegalStateException - if the instance invokes thismethod while the instance is in a state that does not allow theinstance to invoke this method, or if the instance does not havea local interface. |
| getEJBObject | | 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:
IllegalStateException - Thrown if the instance invokes thismethod while the instance is in a state that does not allow theinstance to invoke this method, or if the instance does not havea remote interface. |
| getPrimaryKey | | 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:
IllegalStateException - Thrown if the instance invokes thismethod while the instance is in a state that does not allow theinstance to invoke this method. |
