1. trait CAPSEntityTable extends EntityTable[SparkTable]

   

2. case class CAPSNodeTable(mapping: NodeMapping, table: SparkTable) extends NodeTable[SparkTable] with CAPSEntityTable with Product with Serializable

   

3. case class CAPSRelationshipTable(mapping: RelationshipMapping, table: SparkTable) extends RelationshipTable[SparkTable] with CAPSEntityTable with Product with Serializable

   

4. sealed trait EntityTable[T <: CypherTable[String]] extends AnyRef

   

   An entity table describes how to map an input data frame to a Cypher entity (i.e.

   An entity table describes how to map an input data frame to a Cypher entity (i.e. nodes or relationships).

5. sealed trait GraphEntity extends Product

   

6. case class Labels(labels: String*) extends Annotation with StaticAnnotation with Product with Serializable

   

   Annotation to use when mapping a case class to a node with more than one label, or a label different to the class name.

   Annotation to use when mapping a case class to a node with more than one label, or a label different to the class name.

   @ Labels("Person", "Employee")
   case class Employee(id: Long, name: String, salary: Double)

   labels

   the labels that the node has.

7. trait Node extends GraphEntity

   

   If a node has no label annotation, then the class name is used as its label.

   If a node has no label annotation, then the class name is used as its label. If a Labels annotation, for example @Labels("Person", "Mammal"), is present, then the labels from that annotation are used instead.

8. abstract class NodeTable[T <: CypherTable[String]] extends EntityTable[T]

   

   A node table describes how to map an input data frame to a Cypher node.

   A node table describes how to map an input data frame to a Cypher node.

   A node table needs to have the canonical column ordering specified by EntityMapping#allSourceKeys. The easiest way to transform the table to a canonical column ordering is to use one of the constructors on the companion object.

   Column names prefixed with property# are decoded by org.opencypher.spark.api.io.util.StringEncodingUtilities to recover the original property name.

9. trait Relationship extends GraphEntity

   

   If a relationship has no type annotation, then the class name in all caps is used as its type.

   If a relationship has no type annotation, then the class name in all caps is used as its type. If a Type annotation, for example @RelationshipType("FRIEND_OF") is present, then the type from that annotation is used instead.

10. abstract class RelationshipTable[T <: CypherTable[String]] extends EntityTable[T]

    

    A relationship table describes how to map an input data frame to a Cypher relationship.

    A relationship table describes how to map an input data frame to a Cypher relationship.

    A relationship table needs to have the canonical column ordering specified by EntityMapping#allSourceKeys. The easiest way to transform the table to a canonical column ordering is to use one of the constructors on the companion object.

11. case class RelationshipType(relType: String) extends Annotation with StaticAnnotation with Product with Serializable

    

    Annotation to use when mapping a case class to a relationship with a different relationship type to the class name.

    Annotation to use when mapping a case class to a relationship with a different relationship type to the class name.

    @ RelationshipType("FRIEND_OF")
    case class Friend(id: Long, src: Long, dst: Long, since: Int)

    relType

    the relationship type that the relationship has.
