public interface FastTripleBunch extends JenaSetHashOptimized<Triple>, org.apache.jena.atlas.lib.Copyable<FastTripleBunch>
A bunch of triples - a stripped-down set with specialized methods. A bunch is expected to store triples that share some useful property (such as having the same subject or predicate).

  • Method Details

    • isArray

      boolean isArray()
      Answer true iff this bunch is implemented as an array. This field is used to optimize some operations by avoiding the need for instanceOf tests.
      Returns:
      true iff this bunch is implemented as an arrays

    • anyMatchRandomOrder

      boolean anyMatchRandomOrder(Predicate<Triple> predicate)
      This method is used to optimize _PO match operations. The JenaMapSetCommon.anyMatch(Predicate) method is faster if there are only a few matches. This method is faster if there are many matches and the set is ordered in an unfavorable way. _PO matches usually fall into this category.
      Parameters:
      predicate - the predicate to match
      Returns:
      true if any triple in the bunch matches the predicate
