public AbstractPostInsertGenerator()

Method Detail

generate

public Serializable generate(SharedSessionContractImplementor s,
                             Object obj)

Description copied from interface: IdentifierGenerator

Generate a new identifier.

Specified by:

generate in interface IdentifierGenerator

Parameters:

s - The session from which the request originates

obj - the entity or collection (idbag) for which the id is being generated

Returns:

a new identifier

supportsBulkInsertionIdentifierGeneration

public boolean supportsBulkInsertionIdentifierGeneration()

Description copied from interface: BulkInsertionCapableIdentifierGenerator

Given the configuration of this generator, is identifier generation as part of bulk insertion supported?

IMPL NOTE : Mainly here to allow stuff like SequenceStyleGenerator which *can* support this based on configuration

Specified by:

supportsBulkInsertionIdentifierGeneration in interface BulkInsertionCapableIdentifierGenerator

Returns:

true if bulk insertions are supported; false otherwise.

determineBulkInsertionIdentifierGenerationSelectFragment

public String determineBulkInsertionIdentifierGenerationSelectFragment(SqlStringGenerationContext context)

Description copied from interface: BulkInsertionCapableIdentifierGenerator

Return the select expression fragment, if any, that generates the identifier values.

Specified by:

determineBulkInsertionIdentifierGenerationSelectFragment in interface BulkInsertionCapableIdentifierGenerator

Parameters:

context - A context for SQL string generation.

Returns:

The identifier value generation fragment (SQL). null indicates that no fragment is needed.
