public class CardinalityQRestrictionImpl extends QualifiedRestrictionImpl implements CardinalityQRestriction

Implementation of the exact qualified cardinality restriction

  • Field Details

    • factory

      public static Implementation factory
      A factory for generating QualifiedRestriction facets from nodes in enhanced graphs. Note: should not be invoked directly by user code: use as() instead.

  • Constructor Details

    • CardinalityQRestrictionImpl

      public CardinalityQRestrictionImpl(Node n, EnhGraph g)

      Construct a qualified restriction node represented by the given node in the given graph.

      Parameters:
      n - The node that represents the resource
      g - The enh graph that contains n

  • Method Details

    • isCardinalityQRestriction

      public static boolean isCardinalityQRestriction(Node node, EnhGraph eg)

    • isValid

      public boolean isValid()
      Description copied from class: Polymorphic
      answer true iff this enhanced node is still underpinned in the graph by triples appropriate to its type.
      Overrides:
      isValid in class QualifiedRestrictionImpl

    • setCardinalityQ

      public void setCardinalityQ(int cardinality)

      Assert that this restriction restricts the property to have the given cardinality. Any existing statements for cardinalityQ will be removed.

      Specified by:
      setCardinalityQ in interface CardinalityQRestriction
      Parameters:
      cardinality - The cardinality of the restricted property
      Throws:
      ProfileException - If the Profile.CARDINALITY_Q() property is not supported in the current language profile.

    • getCardinalityQ

      public int getCardinalityQ()

      Answer the cardinality of the restricted property.

      Specified by:
      getCardinalityQ in interface CardinalityQRestriction
      Returns:
      The cardinality of the restricted property
      Throws:
      ProfileException - If the Profile.CARDINALITY_Q() property is not supported in the current language profile.

    • hasCardinalityQ

      public boolean hasCardinalityQ(int cardinality)

      Answer true if this property restriction has the given cardinality.

      Specified by:
      hasCardinalityQ in interface CardinalityQRestriction
      Parameters:
      cardinality - The cardinality to test against
      Returns:
      True if the given cardinality is the cardinality of the restricted property in this restriction
      Throws:
      ProfileException - If the Profile.CARDINALITY_Q() property is not supported in the current language profile.

    • removeCardinalityQ

      public void removeCardinalityQ(int cardinality)

      Remove the statement that this restriction has the given cardinality for the restricted property. If this statement is not true of the current model, nothing happens.

      Specified by:
      removeCardinalityQ in interface CardinalityQRestriction
      Parameters:
      cardinality - A cardinality value to be removed from this restriction
      Throws:
      ProfileException - If the Profile.CARDINALITY_Q() property is not supported in the current language profile.
