Example 1 with AbstractStringCalc

use of mondrian.calc.impl.AbstractStringCalc in project mondrian by pentaho.

the class FormatFunDef method compileCall.

public Calc compileCall(ResolvedFunCall call, ExpCompiler compiler) {
    final Exp[] args = call.getArgs();
    final Calc calc = compiler.compileScalar(call.getArg(0), true);
    final Locale locale = compiler.getEvaluator().getConnectionLocale();
    if (args[1] instanceof Literal) {
        // Constant string expression: optimize by
        // compiling format string.
        String formatString = (String) ((Literal) args[1]).getValue();
        final Format format = new Format(formatString, locale);
        return new AbstractStringCalc(call, new Calc[] { calc }) {

            public String evaluateString(Evaluator evaluator) {
                final Object o = calc.evaluate(evaluator);
                return format.format(o);
            }
        };

        // Variable string expression
        final StringCalc stringCalc = compiler.compileString(call.getArg(1));
