Returns:
true if changes should be flushed, otherwise false.
Since:
1.0.3, 1.2.0

setIgnoreDetachedStateFieldForProxySerialization

public void setIgnoreDetachedStateFieldForProxySerialization(boolean ignoreDSF)
Whether OpenJPA should ignore the DetachedStateField value when determining if our Proxy classes should be removed during serialization.

Starting with version 2.0.0, when the DetachedStateFiled==true, the build time $proxy classes will not be removed.

Prior to version 2.0.0, the DetachedStateFiled was not used and the $proxy classes were not being removed during serialization after the Persistence context was cleared.

Parameters:
ignoreDSF - if true the old Proxy serialization behavior will be used.
Since:
2.0.0

getIgnoreDetachedStateFieldForProxySerialization

public boolean getIgnoreDetachedStateFieldForProxySerialization()
Whether OpenJPA should ignore the DetachedStateField value when determining if our Proxy classes should be removed during serialization.

Starting with version 2.0.0, when the DetachedStateFiled==true, the build time $proxy classes will not be removed.

Prior to version 2.0.0, the DetachedStateFiled was not used and the $proxy classes were not being removed during serialization after the Persistence context was cleared.

Since:
1.0.3, 1.2.0

getCopyOnDetach

public boolean getCopyOnDetach()
Affirms if detached entities are copy of the managed instances. Before this option is introduced, detached entities were by default copies of the managed entities unless the entire cache is detached, only then the detachment was in-place. This option changes the default behavior such that detachment is now in-place by default. To emulate the previous copy-on-detach behavior set this option to true. If the entire cache is being detached (when the persistence context is closed, for example), the detachement

Since:
2.0.0

setCopyOnDetach

public void setCopyOnDetach(boolean copyOnDetach)
Sets if detached entities are copy of the managed instances. Before this option is introduced, detached entities were by default copies of the managed entities unless the entire cache is detached, only then the detachment was in-place. This option changes the default behavior such that detachment is now in-place by default. To emulate the previous copy-on-detach behavior set this option to true.

Since:

useJPA2 - true if the JPA 2.0 default name should be used. false if the 1.x name should be used.
Since:
2.0.0

getPrivatePersistentProperties

public boolean getPrivatePersistentProperties()
Whether OpenJPA allows private, non-transient properties to be persistent. Prior to OpenJPA 2.0, if property access was used, private properties were considered persistent. This is contrary to the JPA specification, which states that persistent properties must be public or protected. The default value is false.

Returns:
true if non-transient private properties should be persistent
Since:
2.0.0

setPrivatePersistentProperties

public void setAbstractMappingUniDirectional(boolean isAbstractMappingUniDirectional)
Whether OpenJPA allows bi-directional relationship in the MappedSuperclass. Prior to OpenJPA 2.0, the bi-directional relationship in the MappedSuperclass, is not blocked. This is contrary to the JPA specification, which states that persistent relationships defined by a mapped superclass must be unidirectional.

Parameters:
isAbstractMappingUniDirectional - true if relationship defined in the MappedSuperclass must be uni-directional
Since:
2.0.0

isAbstractMappingUniDirectional

public boolean isAbstractMappingUniDirectional()
Whether OpenJPA allows bi-directional relationship in the MappedSuperclass. Prior to OpenJPA 2.0, the bi-directional relationship in the MappedSuperclass, is not blocked.

Since:
2.0.0

setNonDefaultMappingAllowed

public void setNonDefaultMappingAllowed(boolean isNonDefaultMappingAllowed)

Since:
2.0.0

isNonDefaultMappingAllowed

public boolean isNonDefaultMappingAllowed()
