Type Members

1. trait EntityMapping extends AnyRef

   

   Represents a map from node property keys to keys in the source data.

2. final case class NodeMapping extends EntityMapping with Product with Serializable

   

   Represents a mapping from a source with key-based access to node components (e.g.

   Represents a mapping from a source with key-based access to node components (e.g. a table definition) to a Cypher node. The purpose of this class is to define a mapping from an external data source to a property graph.

   Construct a NodeMapping starting with NodeMapping#on.

   The sourceIdKey represents a key to the node identifier within the source data. The retrieved value from the source data is expected to be a scala.Long value that is unique among nodes.

   The impliedLabels represent a set of node labels.

   The optionalLabelMapping represent a map from node labels to keys in the source data. The retrieved value from the source data is expected to be a scala.Boolean value indicating if the label is present on that node.

   The propertyMapping represents a map from node property keys to keys in the source data. The retrieved value from the source is expected to be convertible to a valid org.opencypher.okapi.api.value.CypherValue.

3. final case class RelationshipMapping extends EntityMapping with Product with Serializable

   

   Represents a mapping from a source with key-based access to relationship components (e.g.

   Represents a mapping from a source with key-based access to relationship components (e.g. a table definition) to a Cypher relationship. The purpose of this class is to define a mapping from an external data source to a property graph.

   Construct a RelationshipMapping starting with RelationshipMapping#on.
