Example 1 with ArrayIterator

use of org.mvel2.templates.util.ArrayIterator in project mvel by mikebrock.

the class ForEachNode method eval.

public Object eval(TemplateRuntime runtime, TemplateOutputStream appender, Object ctx, VariableResolverFactory factory) {
    Iterator[] iters = new Iterator[item.length];
    Object o;
    for (int i = 0; i < iters.length; i++) {
        if ((o = MVEL.eval(expression[i], ctx, factory)) instanceof Iterable) {
            iters[i] = ((Iterable) o).iterator();
        } else if (o instanceof Object[]) {
            iters[i] = new ArrayIterator((Object[]) o);
        } else {
            throw new TemplateRuntimeError("cannot iterate object type: " + o.getClass().getName());
        }
    }
    Map<String, Object> locals = new HashMap<String, Object>();
    MapVariableResolverFactory localFactory = new MapVariableResolverFactory(locals, factory);
    int iterate = iters.length;
    while (true) {
        for (int i = 0; i < iters.length; i++) {
