public java.lang.Object exec(java.util.List arguments)

- Invokes the method, passing it the arguments from the list.

get
public TemplateModel get(int index)

- Description copied from interface:
TemplateSequenceModel
- Retrieves the i-th template model in this sequence.
- Specified by:
get
in interface TemplateSequenceModel
- 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

- Returns:
- the number of items in the list.
