Method Detail

get

public TemplateModel get(int index)
                  throws TemplateModelException

Returns PyObject.__finditem__(int).

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

size

public int size()
         throws TemplateModelException

Returns PyObject.__len__().

Specified by:

size in interface TemplateSequenceModel

Returns:

the number of items in the list.

Throws:

TemplateModelException

iterator

public TemplateModelIterator iterator()

Description copied from interface: TemplateCollectionModel

Retrieves a template model iterator that is used to iterate over the elements in this collection.

Specified by:

iterator in interface TemplateCollectionModel
