Constructor Details

IdentityIdGenerator

public IdentityIdGenerator(BibernateDatabaseSettings bibernateDatabaseSettings,
 List<String> executedQueries)

Constructs an IdentityIdGenerator with the specified Bibernate database settings and a list to store executed queries.

Parameters:

bibernateDatabaseSettings - The database settings for Bibernate.

executedQueries - The list to store executed queries.

Method Details

type

public GenerationType type()

Returns IDENTITY GenerationType for further understanding of what type of generator we are dealing with

Specified by:

type in interface Generator

Returns:

the generation type

handle

public <T> void handle(Class<T> entityClass,
 Collection<T> entities,
 DataSource dataSource)

Handles the generation of identity-based primary keys for a collection of entities and inserts the entities into the database using batch processing. Gets generated id from the database and sets it to the entity. If the method will be performed in transaction then id will be cleaned up from the entity in case of rollback.

Specified by:

handle in interface Generator

Type Parameters:

T - The type of entities in the collection.

Parameters:

entityClass - The class of the entities being handled.

entities - The collection of entities for which primary keys are generated.

dataSource - The data source for obtaining a database connection.

updateEntity

private void updateEntity(Object entity,
 Object value)
