AccessIntent (IBM WebSphere Application Server, Release 9.0)

```
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.

Methods
Modifier and Type	Method and Description
`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.
`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
`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.
`int`	`getCollectionScope()` Returns the collection scope, which indicates the maximum lifespan of a lazy collection.
`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.
`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.
`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
`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
`boolean`	`getPessimisticUpdateHintExclusive()` Deprecated.
`boolean`	`getPessimisticUpdateHintNoCollision()` Deprecated.
`boolean`	`getPessimisticUpdateHintWeakestLockAtLoad()` Deprecated.
`int`	`getPessimisticUpdateLockHint()`
`ReadAheadHint`	`getReadAheadHint()` Returns the ReadAheadHint requested by the application for the currently executing finder.
`int`	`getResourceManagerPreFetchIncrement()` Returns the number of elements the application requests be contained in each segment of a a query made on a database.
`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.
