Method Details

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, unless the default value for that case was also specified in the template.

size

public int size()

Specified by:

size in interface TemplateSequenceModel

Returns:

the number of items in the list.

getWrappedObject

public Object getWrappedObject()

Returns the original List of TemplateModel-s, so it's not a fully unwrapped value.
