Field Detail

eventManager

protected DESCRIPTOR_EVENT_MANAGER extends CoreDescriptorEventManager eventManager

field

instantiationPolicy

protected INSTANTIATION_POLICY extends org.eclipse.persistence.internal.core.descriptors.CoreInstantiationPolicy instantiationPolicy

inheritancePolicy

protected INHERITANCE_POLICY extends CoreInheritancePolicy inheritancePolicy

objectBuilder

protected OBJECT_BUILDER extends org.eclipse.persistence.internal.core.descriptors.CoreObjectBuilder objectBuilder

Constructor Detail

CoreDescriptor

public CoreDescriptor()
Method Detail

addAttributeGroup

public void addAttributeGroup(ATTRIBUTE_GROUP group)
Adds the attribute group to this descriptor.

Parameters:
group -

getAttributeGroup

public ATTRIBUTE_GROUP getAttributeGroup(java.lang.String name)
PUBLIC: Returns the attribute group corresponding to the name provided. If no group is found with the specified name, null is returned.


getAttributeGroups

public java.util.Map<java.lang.String,ATTRIBUTE_GROUP> getAttributeGroups()
ADVANCED: Returns the attribute groups for this Descriptor.


getEventManager

public abstract DESCRIPTOR_EVENT_MANAGER getEventManager()
PUBLIC: Get the event manager for the descriptor. The event manager is responsible for managing the pre/post selectors.


getInheritancePolicy

public abstract INHERITANCE_POLICY getInheritancePolicy()
PUBLIC: The inheritance policy is used to define how a descriptor takes part in inheritance. All inheritance properties for both child and parent classes is configured in inheritance policy. Caution must be used in using this method as it lazy initializes an inheritance policy. Calling this on a descriptor that does not use inheritance will cause problems, #hasInheritance() must always first be called.


getInstantiationPolicy

public abstract INSTANTIATION_POLICY getInstantiationPolicy()
INTERNAL: Returns the instantiation policy.


getJavaClass

public abstract java.lang.Class getJavaClass()
PUBLIC: Return the java class.


getObjectBuilder

public abstract OBJECT_BUILDER getObjectBuilder()
INTERNAL: Return the object builder


getPrimaryKeyFieldNames

public abstract java.util.List<java.lang.String> getPrimaryKeyFieldNames()
PUBLIC: Return the names of all the primary keys.


getPrimaryKeyFields

public abstract java.util.List<FIELD> getPrimaryKeyFields()
INTERNAL: Return all the primary key fields


getTypedField

public abstract FIELD getTypedField(FIELD field)
INTERNAL: searches first descriptor than its ReturningPolicy for an equal field


hasEventManager

public abstract boolean hasEventManager()
INTERNAL: returns true if a DescriptorEventManager has been set.


hasInheritance

public abstract boolean hasInheritance()
INTERNAL: Return if this descriptor is involved in inheritance, (is child or parent). Note: If this class is part of table per class inheritance strategy this method will return false.

See Also:
hasTablePerClassPolicy()

setEventManager

public abstract void setEventManager(DESCRIPTOR_EVENT_MANAGER eventManager)
INTERNAL: Set the event manager for the descriptor. The event manager is responsible for managing the pre/post selectors.


setInheritancePolicy

public abstract void setInheritancePolicy(INHERITANCE_POLICY inheritancePolicy)
INTERNAL: Sets the inheritance policy.


setInstantiationPolicy

public abstract void setInstantiationPolicy(INSTANTIATION_POLICY instantiationPolicy)
INTERNAL: Sets the instantiation policy.


setJavaClass

public abstract void setJavaClass(java.lang.Class javaClass)
PUBLIC: Set the Java class that this descriptor maps. Every descriptor maps one and only one class.


setObjectBuilder

protected abstract void setObjectBuilder(OBJECT_BUILDER objectBuilder)
INTERNAL: Set the ObjectBuilder.


setPrimaryKeyFieldNames

public abstract void setPrimaryKeyFieldNames(LIST primaryKeyFieldNames)
PUBLIC: User can specify a vector of all the primary key field names if primary key is composite.

See Also:
#addPrimaryKeyFieldName(String)

setPrimaryKeyFields

public abstract void setPrimaryKeyFields(java.util.List<FIELD> primaryKeyFields)
PUBLIC: User can specify a vector of all the primary key field names if primary key is composite.

See Also:
#addPrimaryKeyFieldName(String)
