  • Method Details

    • getName

      String getName()
      INTERNAL: Returns the name of the predicate. This will usually be the name of the predicate within its module ('instance-of', '/=', 'starts-with'), but some virtual predicates cannot be reached from the syntax and may return names that will not parse.

    • getSignature

      String getSignature() throws InvalidQueryException
      INTERNAL: Returns a string representing the signature of the predicate. The string consists of a whitespace-separated list of arguments, where each argument is made up of tokens representing the type or cardinality of that argument.

      The instance-of predicate would have a signature of "t t", while /= would have ". .", and in would have ". .+". For full details, see topicmaps.impl.utils.ArgumentValidator.

      Throws:
      InvalidQueryException

    • getCost

      int getCost(boolean[] boundparams)
      INTERNAL.
