 package freemarker.ext.beans;
 
 

A class that will wrap an arbitrary array into freemarker.template.TemplateCollectionModel and freemarker.template.TemplateSequenceModel interfaces. It supports element retrieval through the array[index] syntax and can be iterated as a list.

Creates a new model that wraps the specified array object.

Parameters:
array the array object to wrap into a model.
wrapper the BeansWrapper associated with this model. Every model has to have an associated BeansWrapper instance. The model gains many attributes from its wrapper, including the caching behavior, method exposure level, method-over-item shadowing policy etc.
Throws:
java.lang.IllegalArgumentException if the passed object is not a Java array.
