TemplateSequenceModel

All Superinterfaces:

TemplateModel

All Known Implementing Classes:

SimpleList, SimpleSequence, TemplateModelListSequence
```
public interface TemplateSequenceModel
extends TemplateModel
```
List values in a template data model whose elements are accessed by the index operator should implement this interface. In addition to accessing elements by index and querying size using the ?size built-in, objects that implement this interface can be iterated in <#foreach ...> and <#list ...> directives. The iteration is implemented by calling the get(int) method repeatedly starting from zero and going to size() - 1.

  Retrieves the i-th template model in this sequence.

- Method Detail
  - get
```
TemplateModel get(int index)
           throws TemplateModelException
```
    Retrieves the i-th template model in this sequence.
    
    Returns:
    
    the item at the specified index, or null if the index is out of bounds. Note that a null value is interpreted by FreeMarker as "variable does not exist", and accessing a missing variables is usually considered as an error in the FreeMarker Template Language, so the usage of a bad index will not remain hidden.
    
    Throws:
    
    TemplateModelException
  - size
```
int size()
  throws TemplateModelException
```
    Returns:
    
    the number of items in the list.
    
    Throws:
    
    TemplateModelException
