Examples of com.sun.xacml.cond.FunctionFactory

com.sun.xacml.cond.FunctionFactory
Factory used to create all functions. There are three kinds of factories: general, condition, and target. These provide functions that can be used anywhere, only in a condition's root and only in a target (respectively).
Note that all functions, except for abstract functions, are singletons, so any instance that is added to a factory will be the same one returned from the create methods. This is done because most functions don't have state, so there is no need to have more than one, or to spend the time creating multiple instances that all do the same thing. @since 1.0 @author Marco Barreno @author Seth ProctorAdding generic type support by Christian Mueller (geotools)

    //note that sunxacml includes logical functions in the target
    //instance
    //this is almost certainly wrong
    //abbrevTargetFunctionId filters these out because they do
    //not include the data type in their name (not, and, or, n-or)
    final FunctionFactory factory = FunctionFactory.getTargetInstance();
    final Set functionIds = factory.getSupportedFunctions();
    
    final Set<Object> ret = new HashSet<Object>();
    final String abbrevType = getAbbreviatedType(dataType);
    String functionId;
    for(final Iterator it = functionIds.iterator(); it.hasNext();)
