public interface TemplateHashModelEx
extends TemplateHashModel
```
"extended hash" template language data type; extends TemplateHashModel by allowing iterating through its keys and values. Consider implementing the modern variation of this, TemplateHashModelEx2, which allows the more efficient listing of key-value pairs.
In templates they are used like hashes, but these will also work (among others): myExtHash?size, myExtHash?keys, myExtHash?values, <#list myMap as k, v>.

```
int size()
  throws TemplateModelException
```
    Returns:
    
    the number of key/value mappings in the hash.
    
    Throws:
    
    TemplateModelException
  - keys
```
TemplateCollectionModel keys()
                      throws TemplateModelException
```
    Returns:
    
    a collection containing the keys in the hash. Every element of the returned collection must implement the TemplateScalarModel (as the keys of hashes are always strings).
    
    Throws:
    
    TemplateModelException
  - values
```
TemplateCollectionModel values()
                        throws TemplateModelException
```
    Returns:
    
    a collection containing the values in the hash. The elements of the returned collection can be any kind of TemplateModel-s.
    
    Throws:
    
    TemplateModelException
