Record Class ProvenancedStatement

java.lang.Object
java.lang.Record
ai.chatur.cortex.ProvenancedStatement
Record Components:
predicate - the property of the statement
object - the value of the statement
created - when the statement was approved into the knowledge graph, or null for statements without recorded provenance (those whose origin is StatementOrigin.ONTOLOGY or StatementOrigin.INFERRED)
origin - where the statement came from
literal - whether the object is a literal
datatype - the datatype IRI of a literal object, or null for a resource
language - the language tag of a language-tagged literal object, or null for a resource or a literal without one

public record ProvenancedStatement(Term predicate, Term object, String created, StatementOrigin origin, boolean literal, String datatype, String language) extends Record
A statement about a resource together with its provenance, as returned by CortexQuery.describe(String).

predicate and object carry the display form; literal, datatype, and language carry what Term cannot, so that a statement whose origin is StatementOrigin.ASSERTED can be round-tripped back to RDF as a BranchChange. They mirror BranchStatement, which exists for the same reason on the branch side.

      public ProvenancedStatement(Term predicate, Term object, String created, StatementOrigin origin, boolean literal, String datatype, String language)
      Creates an instance of a ProvenancedStatement record class.
      Parameters:
      predicate - the value for the predicate record component
      object - the value for the object record component
      created - the value for the created record component
      origin - the value for the origin record component

      datatype - the value for the datatype record component
      language - the value for the language record component
  • Method Details

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object
    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object
    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.
    • predicate

      public Term predicate()
      Returns the value of the predicate record component.
      Returns:
      the value of the predicate record component
    • object

      public Term object()
      Returns the value of the object record component.
      Returns:
      the value of the object record component
    • created

      public String created()
      Returns the value of the created record component.
      Returns:
      the value of the created record component
    • origin

      public StatementOrigin origin()
      Returns the value of the origin record component.
      Returns:
      the value of the origin record component
    • literal

      public boolean literal()
      Returns the value of the literal record component.
      Returns:
      the value of the literal record component
    • datatype

      public String datatype()
      Returns the value of the datatype record component.
      Returns:
      the value of the datatype record component
    • language

      public String language()
      Returns the value of the language record component.
      Returns:
      the value of the language record component
