Class JavaPredicate

java.lang.Object
net.ontopia.topicmaps.query.spi.JavaPredicate
All Implemented Interfaces:
BasicPredicateIF, PredicateIF
Direct Known Subclasses:
FilterPredicate, ProcessPredicate
public abstract class JavaPredicate extends Object implements BasicPredicateIF
INTERNAL: Abstract predicate class that works as a common superclass for the real predicate classes. Don't subclass this one directly; instead, subclass one of its subclasses, FilterPredicate or ProcessPredicated, depending on what kind of predicate you want.

  • Method Details

    • getName

      public String getName()
      Description copied from interface: PredicateIF
      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.
      Specified by:
      getName in interface PredicateIF

    • getSignature

      public String getSignature()
      Description copied from interface: PredicateIF
      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.
