public Class LoadGroup

Overrides org.eclipse.persistence.core.queries.CoreAttributeGroup.addAttribute.

Doc from org.eclipse.persistence.core.queries.CoreAttributeGroup.addAttribute.

Add a basic attribute or nested attribute with each String representing an attribute on the path to what needs to be included in the AttributeGroup.

Example: group.addAttribute("firstName", group1);
group.addAttribute("manager.address", group2); Note that existing group corresponding to attributeNameOrPath will be overridden with the passed group.

Parameters

attributeNameOrPath:String

A simple attribute, array or attributes forming a path

group:CoreAttributeGroup<ATTRIBUTE_ITEM extends CoreAttributeItem, DESCRIPTOR extends CoreDescriptor<ATTRIBUTE_GROUP extends CoreAttributeGroup, DESCRIPTOR_EVENT_MANAGER extends CoreDescriptorEventManager, FIELD extends CoreField, INHERITANCE_POLICY extends CoreInheritancePolicy, INSTANTIATION_POLICY extends CoreInstantiationPolicy, LIST extends List<E>, OBJECT_BUILDER extends CoreObjectBuilder>>

- an AttributeGroup to be added.

@Override

Overrides org.eclipse.persistence.queries.AttributeGroup.clone.

Doc from java.lang.Object.clone.

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression:

x.clone() != x

x.clone().getClass() == x.getClass()

x.clone().equals(x)

By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass().

By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.

Returns:LoadGroup

a clone of this instance.

@Override

Overrides org.eclipse.persistence.queries.AttributeGroup.getGroup.

Returns LoadGroup corresponding to the passed (possibly nested) attribute.

Annotations

@Override

INTERNAL: Return if the load group should load its relationships concurrently.

Overrides org.eclipse.persistence.queries.AttributeGroup.isConcurrent.

ADVANCED: Return if the load group should load its relationships concurrently. This will use the session's server platform's thread pool. Each of the query results objects relationships will be loaded on a different thread. This can improve performance by processing many queries at once. Concurrent load is only supported when a shared cache is used.
