Examples of com.linkedin.data.element.DataElement

com.linkedin.data.element.DataElement
Provides information about a Data object being iterated.
It provides the Data object's name within its parent Data object, the Data object itself, the {@link DataSchema} of the Data object,how depth of the Data object within the object graph being iterated, and a reference to {@link DataElement} providing thesame information about the parent Data object. @author slim
