public class SimpleCollection extends WrappingTemplateModel implements TemplateCollectionModel, Serializable
TemplateCollectionModel. It's able to wrap java.util.Iterator-s and java.util.Collection-s. If you wrap an Iterator, the variable can be <#list>-ed only once!
SimpleSequence instead of this class if you want to wrap Iterators.
SimpleSequence will read all elements of the Iterator, and store them in a List
(this may cause too high resource consumption in some applications), so you can list the variable
for unlimited times. Also, if you want to wrap Collections, and then list the resulting
variable for many times, SimpleSequence may gives better performance, as the
wrapping of non-TemplateModel objects happens only once.
This class is thread-safe. The returned
are not thread-safe.

public TemplateModelIterator iterator()
When you wrap an Iterator and you get TemplateModelIterator for multiple times, only on of the returned TemplateModelIterator instances can be really used. When you have called a method of a TemplateModelIterator instance, all other instance will throw a TemplateModelException when you try to call their methods, since the wrapped Iterator can't return the first element anymore.
