Examples of org.geotools.filter.FunctionExpressionImpl

org.geotools.filter.FunctionExpressionImpl
Abstract class for a function expression implementation
By default this implementation returns the provided {@link #fallback} value. To implementa function please override the {@link #evaluate(Object)} method. @author James Macgill, PSU @source $URL$

        FunctionName name = new FunctionNameImpl(
                "test",

        FunctionExpressionImpl f = new FunctionExpressionImpl(name) {
        };
        
        assertEquals(-2, f.getFunctionName().getArgumentCount());
