Method Detail

getReference back to summary

getReference	back to summary
public T getReference(Serializable id) Return the persistent instance with the given identifier, assuming that the instance exists. This method might return a proxied instance that is initialized on-demand, when a non-identifier method is accessed. You should not use this method to determine if an instance exists; to check for existence, use `load` instead. Use this only to retrieve an instance that you assume exists, where non-existence would be an actual error. Parameters id:Serializable The identifier for which to obtain a reference Returns:T the persistent instance or proxy

public T getReference(Serializable id)

Return the persistent instance with the given identifier, assuming that the instance exists. This method might return a proxied instance that is initialized on-demand, when a non-identifier method is accessed. You should not use this method to determine if an instance exists; to check for existence, use load instead. Use this only to retrieve an instance that you assume exists, where non-existence would be an actual error.

Parameters

id:Serializable: The identifier for which to obtain a reference

Returns:T

the persistent instance or proxy

load back to summary

load	back to summary
public T load(Serializable id) Return the persistent instance with the given identifier, or null if there is no such persistent instance. If the instance is already associated with the session, return that instance, initializing it if needed. This method never returns an uninitialized instance. Parameters id:Serializable The identifier Returns:T The persistent instance or `null`

public T load(Serializable id)

Return the persistent instance with the given identifier, or null if there is no such persistent instance. If the instance is already associated with the session, return that instance, initializing it if needed. This method never returns an uninitialized instance.

Parameters

id:Serializable: The identifier

Returns:T

The persistent instance or null

loadOptional back to summary

loadOptional	back to summary
public Optional<T> loadOptional(Serializable id) Same semantic as `load` except that here `Optional` is returned to handle nullability. Parameters id:Serializable The identifier Returns:Optional<T> The persistent instance, if one, wrapped in Optional

public Optional<T> loadOptional(Serializable id)

Same semantic as load except that here Optional is returned to handle nullability.

Parameters

id:Serializable: The identifier

Returns:Optional<T>

The persistent instance, if one, wrapped in Optional

public IdentifierLoadAccess<T> with(LockOptions lockOptions)

Specify the LockOptions to use when retrieving the entity.

Parameters

public IdentifierLoadAccess<T> with(CacheMode cacheMode) Specify the `CacheMode` to use when retrieving the entity. Parameters cacheMode:CacheMode The CacheMode to use. Returns:IdentifierLoadAccess<T> `this`, for method chaining

public IdentifierLoadAccess<T> with(CacheMode cacheMode)

Specify the CacheMode to use when retrieving the entity.

Parameters

cacheMode:CacheMode: The CacheMode to use.

Returns:IdentifierLoadAccess<T>
