public abstract class AbstractTableBasedBulkIdHandler extends Object
MultiTableBulkIdStrategy.UpdateHandler
and MultiTableBulkIdStrategy.DeleteHandler
implementations through
TableBasedUpdateHandlerImpl
and TableBasedDeleteHandlerImpl
respectively.
Mainly supports common activities like:WHERE
clause (if one) - processWhereClause(antlr.collections.AST)
SELECT
clause for the id-table insert - generateIdInsertSelect(java.lang.String, org.hibernate.hql.spi.id.IdTableInfo, org.hibernate.hql.spi.id.AbstractTableBasedBulkIdHandler.ProcessedWhereClause)
generateIdSubselect(org.hibernate.persister.entity.Queryable, org.hibernate.hql.spi.id.IdTableInfo)
