All Implemented Interfaces:

Component, Injectable, SessionScopedComponent, DebugInfo, OidGenerator

Direct Known Subclasses:

TimeBasedOidGenerator

public class SimpleOidGenerator
extends OidGeneratorAbstract

Generates OIDs based on monotonically.

Specifies the OidStringifierDirect as the OID stringifier (SerialOid is conformant)).

Nested Class Summary

static class

SimpleOidGenerator.Memento

Constructor Summary

SimpleOidGenerator()

SimpleOidGenerator(long seed)
Persistent Oids count up from the provided seed parameter, while Oid.isTransient() transient Oids count down.

Method Summary

void	convertTransientToPersistentOid(Oid oid) Convert the Oid from transient to persistent, storing the previous Oid as Oid.getPrevious()
SerialOid	createTransientOid(java.lang.Object object) Create a new transient Oid for the supplied pojo, uniquely distinguishable from any other Oid.
void	debugData(DebugString debug)
java.lang.String	debugTitle()
SimpleOidGenerator.Memento	getMemento()
java.lang.String	name()
void	resetTo(SimpleOidGenerator.Memento memento) Reset to a SimpleOidGenerator.Memento previously obtained via getMemento().

Constructor Detail

SimpleOidGenerator

public SimpleOidGenerator()

SimpleOidGenerator

public SimpleOidGenerator(long seed)

Persistent Oids count up from the provided seed parameter, while Oid.isTransient() transient Oids count down.

SimpleOidGenerator

public SimpleOidGenerator(SimpleOidGenerator.Memento memento)

Method Detail

name

public java.lang.String name()

createTransientOid

public SerialOid createTransientOid(java.lang.Object object)

Description copied from interface: OidGenerator

Create a new transient Oid for the supplied pojo, uniquely distinguishable from any other Oid.

convertTransientToPersistentOid

public void convertTransientToPersistentOid(Oid oid)

Description copied from interface: OidGenerator

Convert the Oid from transient to persistent, storing the previous Oid as Oid.getPrevious()

Implementation notes:

• Note that the AdapterManager will need to be updated so that the adapter is re-mapped by the new Oid. However, the not the responsibility of the OidGenerator to do this; it merely ensures that the Oid is in the correct new state.
• Some implementations may require that state be set up on the Oid prior to call. Check for details.

getMemento

public SimpleOidGenerator.Memento getMemento()

resetTo

public void resetTo(SimpleOidGenerator.Memento memento)

Reset to a SimpleOidGenerator.Memento previously obtained via getMemento().

Used in particular by the InMemoryObjectStore to reset (a new OidGenerator is created each time).

debugData

public void debugData(DebugString debug)

debugTitle

public java.lang.String debugTitle()
