Example 2 with EJBLocalObjectImpl

use of com.sun.ejb.containers.EJBLocalObjectImpl in project Payara by payara.

the class ActiveTxCache method getEJBLocalObjectForPrimaryKey.

/**
 * Called only from the Persistence Manager for EJB2.0 CMP EntityBeans.
 * Called only during cascade delete......
 * This is a private API between the PM and Container because there
 * is no standard API defined in EJB2.0 for the PM to get an EJBLocalObject
 * for a primary key (findByPrimaryKey cant be used because it may
 * not run in the same tx).
 *
 * Example 1:
 *  A cascadeDeletes B and B calls getA() (expected return value: null)
 *
 *  In the above case, getA() eventualy calls getEJBLocalObjectForPrimaryKey(PK_of_A, Ctx_of_B)
 *  We first check if B is in the process of being cascade deleted by checking the
 *  cascadeDeleteBeforeEJBRemove flag. If this flag is true, only then we bother to check if
 *  the Context associated with the PK_of_A in this transaction is marked for cascade delete
 *  which can be figured out by checking isCascadeDeleteAfterSuperEJBRemove() in A's context.
 *  If A is marked for cascade delete then we return null else the EJBLocalObject associated
 *  with A.
 *
 * Example 2:
 *  C cascadeDeletes B and B calls getA() (expected return value: EJBLocalObject for PK_of_A)
 *
 *  In the above case, getA() eventualy calls getEJBLocalObjectForPrimaryKey(PK_of_A, Ctx_of_B)
 *  We first check if B is in the process of being cascade deleted by checking the
 *  cascadeDeleteBeforeEJBRemove flag. This flag will be true, and hence we check if
 *  the Context associated with the PK_of_A in this transaction is marked for cascade delete
 *  which can be figured out by checking isCascadeDeleteAfterSuperEJBRemove() in A's context.
 *  In this case this flag will be false and hcen we return the ejbLocalObject
 * Example 2:
 *  B is *NOT* cascade deleted and B calls getA() (expected return value: EJBLocalObject for PK_of_A)
 *
 *  In the above case, getA() eventualy calls getEJBLocalObjectForPrimaryKey(PK_of_A, Ctx_of_B)
 *  We first check if B is in the process of being cascade deleted by checking the
 *  cascadeDeleteBeforeEJBRemove flag. This flag will be FALSE, and hence we do not make
 *  any further check and return the EJBLocalObject associated with A
 *
 * @param pkey The primary key for which the EJBLocalObject is required
 * @param ctx The context associated with the bean from which the accessor method is invoked
 * @return The EJBLocalObject associated with the PK or null if it is cascade deleted.
