public IteratorModel(Iterator iterator,
    BeansWrapper wrapper) 
{
    
        super(iterator, wrapper);
}

Creates a new model that wraps the specified iterator object.

Parameters:

iterator - the iterator object to wrap into a model.

wrapper - the BeansWrapper associated with this model. Every model has to have an associated BeansWrapper instance. The model gains many attributes from its wrapper, including the caching behavior, method exposure level, method-over-item shadowing policy etc.

 public boolean getAsBoolean() 
{
        return hasNext();
}

Returns Iterator#hasNext() . Therefore, an iterator that has no more element evaluates to false, and an iterator that has further elements evaluates to true.

 public boolean hasNext() 
{
        return ((Iterator)object).hasNext();
}

Calls underlying Iterator#hasNext() .

 public TemplateModelIterator iterator() throws TemplateModelException 
{
        synchronized(this) {
            if(accessed) {
                throw new TemplateModelException(
                    "This collection is stateful and can not be iterated over the" +
                    " second time.");
            }
            accessed = true;
        }
        return this;
}

This allows the iterator to be used in a <foreach> block.

 public TemplateModel next() throws TemplateModelException 
{
        try {
            return wrap(((Iterator)object).next());
        }
        catch(NoSuchElementException e) {
            throw new TemplateModelException(
                "No more elements in the iterator.", e);
        }
}

Calls underlying Iterator#next() and wraps the result.
