类 AbstractTableBasedBulkIdHandler

java.lang.Object

org.hibernate.hql.spi.id.AbstractTableBasedBulkIdHandler

直接已知子类:

AbstractIdsBulkIdHandler, TableBasedDeleteHandlerImpl, TableBasedUpdateHandlerImpl

public abstract class AbstractTableBasedBulkIdHandler
extends Object

Convenience base class for MultiTableBulkIdStrategy.UpdateHandler and MultiTableBulkIdStrategy.DeleteHandler implementations through TableBasedUpdateHandlerImpl and TableBasedDeleteHandlerImpl respectively.

Mainly supports common activities like:

• processing the original WHERE clause (if one) - processWhereClause(antlr.collections.AST)
• generating the proper SELECT clause for the id-table insert - generateIdInsertSelect(java.lang.String, org.hibernate.hql.spi.id.IdTableInfo, org.hibernate.hql.spi.id.AbstractTableBasedBulkIdHandler.ProcessedWhereClause)
• generating the sub-select from the id-table - generateIdSubselect(org.hibernate.persister.entity.Queryable, org.hibernate.hql.spi.id.IdTableInfo)

构造器详细资料

AbstractTableBasedBulkIdHandler

public AbstractTableBasedBulkIdHandler(SessionFactoryImplementor sessionFactory,
                                       HqlSqlWalker walker)

方法详细资料

factory

protected SessionFactoryImplementor factory()

walker

protected HqlSqlWalker walker()

getTargetedQueryable

public abstract Queryable getTargetedQueryable()

processWhereClause

protected AbstractTableBasedBulkIdHandler.ProcessedWhereClause processWhereClause(antlr.collections.AST whereClause)

Interprets the WHERE clause from the user-defined update/delete query

参数:

whereClause - The user-defined WHERE clause

返回:

The bulk-id-ready WHERE clause representation

generateIdInsertSelect

protected String generateIdInsertSelect(String tableAlias,
                                        IdTableInfo idTableInfo,
                                        AbstractTableBasedBulkIdHandler.ProcessedWhereClause whereClause)

Generate the INSERT-SELECT statement for holding matching ids. This is the INSERT used to populate the bulk-id table with ids matching the restrictions defined in the original WHERE clause

参数:

tableAlias - The table alias to use for the entity

whereClause - The processed representation for the user-defined WHERE clause.

返回:

The INSERT-SELECT for populating the bulk-id table.

generateIdSelect

protected Select generateIdSelect(String tableAlias,
                                  AbstractTableBasedBulkIdHandler.ProcessedWhereClause whereClause)

addAnyExtraIdSelectValues

protected void addAnyExtraIdSelectValues(SelectValues selectClause)

Used from generateIdInsertSelect(java.lang.String, org.hibernate.hql.spi.id.IdTableInfo, org.hibernate.hql.spi.id.AbstractTableBasedBulkIdHandler.ProcessedWhereClause) to allow subclasses to define any extra values to be selected (and therefore stored into the bulk-id table). Used to store session identifier, e.g.

参数:

selectClause - The SelectValues that defines the select clause of the insert statement.

generateIdSubselect

protected String generateIdSubselect(Queryable persister,
                                     IdTableInfo idTableInfo)

generateIdSubselect

protected String generateIdSubselect(Queryable persister,
                                     AbstractCollectionPersister cPersister,
                                     IdTableInfo idTableInfo)

getKeyColumnNames

protected static String[] getKeyColumnNames(Queryable persister,
                                            AbstractCollectionPersister cPersister)

appendJoined

protected static void appendJoined(String delimiter,
                                   String[] parts,
                                   StringBuilder sb)

prepareForUse

protected void prepareForUse(Queryable persister,
                             SharedSessionContractImplementor session)

releaseFromUse

protected void releaseFromUse(Queryable persister,
                              SharedSessionContractImplementor session)
