Class OrmTableSynchronized<UJO_IMPL extends Ujo>

java.lang.Object
  org.ujorm.extensions.AbstractUjo
      org.ujorm.implementation.quick.QuickUjo
          org.ujorm.implementation.orm.OrmTableSynchronized<UJO_IMPL>

All Implemented Interfaces:

java.io.Serializable, UjoCloneable, UjoTextable, ExtendedOrmUjo<UJO_IMPL>, OrmUjo, Ujo

public class OrmTableSynchronized<UJO_IMPL extends Ujo>
extends QuickUjo
implements ExtendedOrmUjo<UJO_IMPL>

It is an abstract implementation of the OrmUjo for the multi-thread use. The special feature are:

• some critical method are synchronized
• Session is saved to the ThreadLocal instance so object in different thread must assign a new Session

See the OrmTable javadoc for basic information.

Constructor Detail

OrmTableSynchronized

public OrmTableSynchronized()

Method Detail

readSession

public Session readSession()

Read a session

Specified by:

readSession in interface OrmUjo

writeSession

public void writeSession(Session session)

Write a session

Specified by:

writeSession in interface OrmUjo

writeValue

public void writeValue(UjoProperty property,
                       java.lang.Object value)

A method for an internal use only.

Specified by:

writeValue in interface Ujo

Overrides:

writeValue in class QuickUjo

Parameters:

property - Property must be a direct type only!

See Also:

Property.setValue(Ujo,Object)

readValue

public java.lang.Object readValue(UjoProperty property)

A method for an internal use only.

Specified by:

readValue in interface OrmUjo

Specified by:

readValue in interface Ujo

Overrides:

readValue in class QuickUjo

Parameters:

property - Property must be a direct type only!

Returns:

Property value

See Also:

Property.getValue(Ujo)

readChangedProperties

public UjoProperty[] readChangedProperties(boolean clear)

Returns a changed properties. The method is not the thread save.

Specified by:

readChangedProperties in interface OrmUjo

Parameters:

clear - True value clears the property changes.

get

public final <UJO extends UJO_IMPL,VALUE> VALUE get(UjoProperty<UJO,VALUE> property)

Getter based on UjoProperty implemeted by a pattern UjoExt

set

public final <UJO extends UJO_IMPL,VALUE> UJO_IMPL set(UjoProperty<UJO,VALUE> property,
                                                       VALUE value)

Setter based on UjoProperty. Type of value is checked in the runtime. The method was implemented by a pattern UjoExt.

readAuthorization

public boolean readAuthorization(UjoAction action,
                                 UjoProperty property,
                                 java.lang.Object value)

Test an authorization of the action.

Specified by:

readAuthorization in interface Ujo

Overrides:

readAuthorization in class AbstractUjo

Parameters:

action - Type of request. See constant(s) ACTION_* for more information. The action must not be null, however there is allowed to use a dummy constant UjoAction.DUMMY .

property - A property of the Ujo

value - A value

Returns:

Returns TRUE, if property is authorized.

readFK

public <UJO extends UJO_IMPL> ForeignKey readFK(UjoProperty<UJO,? extends OrmUjo> property)
                  throws java.lang.IllegalStateException

Read the foreign key. This is useful to obtain the foreign key value without (lazy) loading the entire object. If the lazy object is loaded, the method will need the Session to build the ForeignKey instance.
NOTE: The method is designed for developers only, the Ujorm doesn't call it newer.

Specified by:

readFK in interface ExtendedOrmUjo<UJO_IMPL extends Ujo>

Returns:

If no related object is available, then the result has the NULL value.

Throws:

java.lang.IllegalStateException - Method throws an exception for a wrong property type.

java.lang.NullPointerException - Method throws an exception if a Session is missing after a lazy initialization of the property.

newRelation

protected static <UJO extends ExtendedOrmUjo,ITEM extends ExtendedOrmUjo> RelationToMany<UJO,ITEM> newRelation(java.lang.String name,
                                                                                                               java.lang.Class<ITEM> type)

A PropertyIterator Factory creates an new property and assign a next index.

newRelation

protected static <UJO extends ExtendedOrmUjo,ITEM extends ExtendedOrmUjo> RelationToMany<UJO,ITEM> newRelation(java.lang.Class<ITEM> type)

A PropertyIterator Factory creates an new property and assign a next index.
