Class ArrayModel

    • Constructor Detail

      • ArrayModel

        public ArrayModel​(Object array,
                          BeansWrapper wrapper)
        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:
        IllegalArgumentException - if the passed object is not a Java array.
    • Method Detail

      • get

        public TemplateModel get​(int index)
                          throws TemplateModelException
        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.
        Throws:
        TemplateModelException
      • isEmpty

        public boolean isEmpty()
        Description copied from class: BeanModel
        Tells whether the model is empty. It is empty if either the wrapped object is null, or it's a Boolean with false value.
        Specified by:
        isEmpty in interface TemplateHashModel
        Overrides:
        isEmpty in class BeanModel
