Parameter	Type	Description
entity.{attributeName}	Mixed	Current value of the attribute in the entity

Description

Any dataclass attribute is available as a property of an entity, which stores the attribute value for the entity.

Note: Dataclass attributes can also be reached using the alternate syntax with [ ].

The attribute value type depends on the attribute kind (relation or storage):

If attributeName kind is storage:
entity.attributeName returns a value of the same type as attributeName.

If attributeName kind is relatedEntity:
entity.attributeName returns the related entity. Values of the related entity are directly available through cascading properties, for example "myEntity.employer.employees[0].lastname".

If attributeName kind is relatedEntities:
entity.attributeName returns a new entity selection of related entities. Duplications are removed (an unordered entity selection is returned).

Note: For more information on attribute kinds, please refer to the dataClassAttribute.kind property description.

Example

 C_OBJECT($myEntity)

 $myEntity:=ds.Employee.new() //Create a new object of the entity type

 $myEntity.name:="Dupont" // assign 'Dupont' to the 'name' attribute

 $myEntity.firstname:="John" //assign 'John' to the 'firstname' attribute

 $myEntity.save() //save the entity
