readRelationshipFile

public static org.apache.spark.sql.Dataset<Hierarchies.HierarchicalElement> readRelationshipFile(org.apache.spark.sql.SparkSession spark,
                                                                                                 String snomedRelationshipPath)

Reads a Snomed relationship file and converts it to a Hierarchies.HierarchicalElement dataset.

Parameters:

spark - the Spark session

snomedRelationshipPath - path to the SNOMED relationship file

Returns:

a dataset ofHierarchies.HierarchicalElement representing the hierarchical relationship.

withRelationships

public static Hierarchies withRelationships(org.apache.spark.sql.SparkSession spark,
                                            Hierarchies hierarchies,
                                            String snomedRelationshipPath,
                                            String snomedVersion)

Returns a ConceptMaps instance with the specified multiaxial hierarchy. This method reads the LOINC multiaxial hierarchy file and convert it to a Hierarchies.HierarchicalElement dataset, and adds it to the given hierarchies.

Parameters:

spark - the Spark session

hierarchies - a Hierarchies instance to which the hierarchy will be added

snomedRelationshipPath - path to the relationship CSV

snomedVersion - the version of SNOMED being read.

Returns:

a Hierarchies instance that includes the read hierarchy.
