Class PropertyConduitSourceImpl

    • Method Detail

      • create

        public PropertyConduit create​(java.lang.Class rootClass,
                                      java.lang.String expression)
        Description copied from interface: PropertyConduitSource
        Returns a property conduit instance for the given expression. PropertyConduitSource caches the conduits it returns, so despite the name, this method does not always create a new conduit. The cache is cleared if a change to component classes is observed. Callers of this method should observe notifications from the InvalidationEventHub for ComponentClasses and discard any aquired conduits; failure to do so will create memory leaks whenever component classes change (the conduits will keep references to the old classes and classloaders).
        Specified by:
        create in interface PropertyConduitSource
        rootClass - the type of the root object to which the expression is applied
        expression - expression to be evaluated on instances of the root class
        RuntimeException if the expression is invalid (poorly formed, references non-existent properties, etc.)
      • nullTerm

        public static java.lang.NullPointerException nullTerm​(java.lang.String term,
                                                              java.lang.String expression,
                                                              java.lang.Object root)
        May be invoked from fabricated PropertyConduit instances.
