public class EISCompositeCollectionMapping extends AbstractCompositeCollectionMapping implements EISMapping

EIS Composite Collection Mappings map a java.util.Map or java.util.Collection of Java objects to an EIS record in a privately owned, one-to-many relationship according to its descriptor's record type.

Record formats
Record Type Description
Indexed Ordered collection of record elements. The indexed record EIS format enables Java class attribute values to be retrieved by position or index.
Mapped Key-value map based representation of record elements. The mapped record EIS format enables Java class attribute values to be retrieved by an object key.
XML Record/Map representation of an XML DOM element.

      isEISMapping in class DatabaseMapping

    • preInitialize

      public void preInitialize(org.eclipse.persistence.internal.sessions.AbstractSession session)

    • initialize

      public void initialize(org.eclipse.persistence.internal.sessions.AbstractSession session) throws DescriptorException
      INTERNAL: The mapping is initialized with the given session. This mapping is fully initialized after this.
      Overrides:
      initialize in class AbstractCompositeCollectionMapping
      Throws:
      DescriptorException

    • getXPath

      public String getXPath()
