Method Detail

upgradeLock

public static void upgradeLock(Object object,
                               EntityEntry entry,
                               LockOptions lockOptions,
                               EventSource session)

Ensure the LockMode associated with the entity in relation to a persistence context is great or equal to the requested mode.

getReadOnlyFromLoadQueryInfluencers

public static Boolean getReadOnlyFromLoadQueryInfluencers(SharedSessionContractImplementor session)

Determine if the influencers associated with the given Session indicate read-only

getReadOnlyFromLoadQueryInfluencers

public static Boolean getReadOnlyFromLoadQueryInfluencers(LoadQueryInfluencers loadQueryInfluencers)

Determine if given influencers indicate read-only

normalizeKeys

public static <K> K[] normalizeKeys(K[] keys,
                                    BasicValuedModelPart keyPart,
                                    SharedSessionContractImplementor session,
                                    SessionFactoryImplementor sessionFactory)

Normalize an array of keys (primary, foreign or natural).

If the array is already typed as the key type, keys is simply returned.

Otherwise, a new typed array is created and the contents copied from keys to this new array. If key coercion is enabled, the values will be coerced to the key type.

Type Parameters:

K - The key type

Parameters:

keys - The keys to normalize

keyPart - The ModelPart describing the key

createTypedArray

public static <X> X[] createTypedArray(Class<X> elementClass,
                                       int length)

Creates a typed array, as opposed to a generic Object[] that holds the typed values

Parameters:

elementClass - The type of the array elements. See Class.getComponentType()

length - The length to which the array should be created. This is usually zero for Hibernate uses

loadByArrayParameter

public static <R,K> List<R> loadByArrayParameter(K[] idsToInitialize,
                                                       SelectStatement sqlAst,
                                                       JdbcOperationQuerySelect jdbcOperation,
                                                       JdbcParameter jdbcParameter,
                                                       JdbcMapping arrayJdbcMapping,
                                                       Object entityId,
                                                       Object entityInstance,
                                                       EntityMappingType rootEntityDescriptor,
                                                       LockOptions lockOptions,
                                                       Boolean readOnly,
                                                       SharedSessionContractImplementor session)

Load one or more instances of a model part (an entity or collection) based on a SQL ARRAY parameter to specify the keys (as opposed to the more traditional SQL IN predicate approach).

Type Parameters:

R - The type of the model part to load

K - The type of the keys
