Example usage for org.hibernate.id PersistentIdentifierGenerator interface-usage

Introduction

In this page you can find the example usage for org.hibernate.id PersistentIdentifierGenerator interface-usage.

Usage

From source file com.enonic.cms.store.hibernate.id.IntegerBasedCustomIdentifierGenerator.java

/**
 * Class for generating keys for our "user typed" identifiers. Specify table and idClassName, where idClassName is the actual domain class
 * to instantiate passing an Integer to the constructor.
 */
public class IntegerBasedCustomIdentifierGenerator extends TransactionHelper
        implements PersistentIdentifierGenerator, Configurable {

From source file com.literatejava.hibernate.allocator.LinearBlockAllocator.java

/**
 * Allocate Long or Integer keys, using a portable table-based algorithm. 
 * <ul>
 *      <li>This strategy is highly efficient, database-portable, and simplifies/ supersedes HiLo-type strategies.
 *      <li>Keys are allocated in blocks from an "allocator" table, with a current block held in memory;  used by the application as required.
 *      <li>Default block-size of 20 outperforms SEQUENCE allocation by a factor of 10 or more, using only standard SQL &amp; fully portable

From source file de.innovationgate.webgate.api.mysql.GaleraClusterTableGenerator.java

/**
 * Trying to apply the lesson on this article to a hibernate table generator:
 * http://www.joinfu.com/2015/01/understanding-reservations-concurrency-locking-in-nova/
 * Actually the original TableGenerator already does many things right (like querying for the value on the update statement
 * and retrying update while returned rows on it is 0) but still uses "for update" of the select statement.
 * Instead it should remove this and retry also if it gets the deadlock exception (which is still possible)

/**

From source file org.hyperic.hibernate.id.ComboGenerator.java

/**
 * The ComboGenerator dispatches to either a sequence-based generator
 * or a HQMultipleHiLoPerTableGenerator, depending on whether or not the
 * DB supports sequences.  
 */

From source file org.hyperic.hibernate.id.HQMultipleHiLoPerTableGenerator.java

/**
 * 
 * A hilo <tt>IdentifierGenerator</tt> that returns a <tt>Long</tt>, constructed
 * using a hi/lo algorithm. The hi value MUST be fetched in a seperate
 * transaction to the <tt>Session</tt> transaction so the generator must be able

 * This implementation is solely for use inside JBoss using JTA for transactions.
