方法详细资料

generate

public Serializable generate(SharedSessionContractImplementor s,
                             Object obj)

从接口复制的说明: IdentifierGenerator

Generate a new identifier.

指定者:

generate 在接口中 IdentifierGenerator

参数:

s - The session from which the request originates

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

返回:

a new identifier

supportsBulkInsertionIdentifierGeneration

public boolean supportsBulkInsertionIdentifierGeneration()

从接口复制的说明: 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

指定者:

supportsBulkInsertionIdentifierGeneration 在接口中 BulkInsertionCapableIdentifierGenerator

返回:

true if bulk insertions are supported; false otherwise.

determineBulkInsertionIdentifierGenerationSelectFragment

public String determineBulkInsertionIdentifierGenerationSelectFragment(Dialect dialect)

从接口复制的说明: BulkInsertionCapableIdentifierGenerator

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

指定者:

determineBulkInsertionIdentifierGenerationSelectFragment 在接口中 BulkInsertionCapableIdentifierGenerator

参数:

dialect - The dialect against which the insert will be performed.

返回:

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