Interface AccessIntent



  • public interface AccessIntent
    This interface defines the essential access intents available at runtime. The intents are specified in a named component profile and selected by the EJB container at runtime by mapping an application profile task name to the set of available component policies.

    • Method Detail

      • getConcurrencyControl

        int getConcurrencyControl()
        Returns the concurrency control intent, which indicates the application prefers either pessimistic or optimistic concurrency control when accessing the current component in the context of the current transaction.
      • getAccessType

        int getAccessType()
        Returns access type intent, which indicates the application intends either update or read accesss of the current component in the context of the current transaction.
      • getPessimisticUpdateHintWeakestLockAtLoad

        boolean getPessimisticUpdateHintWeakestLockAtLoad()
        Deprecated. 
        Returns a boolean where true indicates that data should be fetched with the weakest lock available; updates may result in lock escalation at store.
        Returns:
        true indicates the data should be fetched with the weakest lock available.
      • getPessimisticUpdateHintNoCollision

        boolean getPessimisticUpdateHintNoCollision()
        Deprecated. 
        Returns a boolean where true indicates that the container should assume that there will be no collision on retrieved rows.
        Returns:
        true indicates the container should assume there will be no collision on retrieved rows.
      • getPessimisticUpdateHintExclusive

        boolean getPessimisticUpdateHintExclusive()
        Deprecated. 
        Returns a boolean where true indicates that the container should assume that there will be collisions on retrieved rows.
        Returns:
        indicates the container should assume there will be collisions on retrieved rows.
      • getPessimisticUpdateLockHint

        int getPessimisticUpdateLockHint()

        int getCollectionScope()
        Returns the collection scope, which indicates the maximum lifespan of a lazy collection.
      • getCollectionIncrement

        int getCollectionIncrement()
        Returns the number of elements the application requests be contained in each segment of the element collection returned by the currently executing finder.
      • getReadAheadHint

        ReadAheadHint getReadAheadHint()
        Returns the ReadAheadHint requested by the application for the currently executing finder.
      • getResourceManagerPreFetchIncrement

        int getResourceManagerPreFetchIncrement()
        Returns the number of elements the application requests be contained in each segment of a a query made on a database.
      • getDeferredOperation

        int getDeferredOperation()
        Persistence Option 1: Returns deferred operation intent, which indicates: DEFERRED_OPERATION_NONE: all ejbCreate/ejbStore/ejbRemove goes immediately to database DEFERRED_OPERATION_CREATE_ONLY , ejbCreate will not insert row into database, but wait till the next ejbStore DEFERRED_OPERATION_ALL, all ejbCreate/ejbStore/ejbRemove will not go to database, until a flush is needed (at the end of transaction or before a finder) current component in the context of the current transaction.
      • getBatch

        boolean getBatch()
        Persistence Option 2: Returns batch intent, which indicates: when DEFERRED_OPERATION_ALL, using database batch update or not to flush the database operations
      • getPartialOperation

        int getPartialOperation()
        Persistence Option 3: Returns deferred operation intent, which indicates: DPARTIAL_OPERATION_NONE: ejbLoad/ejbStore will load and store all the fields DPARTIAL_OPERATION_UPDATE_ONLY: ejbStore will store partial fields by group DPARTIAL_OPERATION_BOTH: ejbLoad/ejbStore will both load and store partial fields by group
      • getPartialOperationGroup

        int getPartialOperationGroup()
        Persistence Option 4: Returns partial operation group intent, which indicates When partial operation is not NONE, use the group index determine which set of the fields are loaded or stored
      • getVerifyReadOnlyData

        int getVerifyReadOnlyData()
        Persistence Option 5: Returns verify read only data intent, which indicates When LifeTimeInCache is set, when to verify the read only data: VERIFY_READ_ONLY_DATA_NONE: read only data will not be verified VERIFY_READ_ONLY_DATA_AT_TRAN_BEGIN: during ejbLoad, verify the readonly data with database to see if data changed. VERIFY_READ_ONLY_DATA_AT_TRAN_END: at the end of transaction m verify the readonly data with database to see if data changed.
