get

public freemarker.template.TemplateModel get(String key)
                                      throws freemarker.template.TemplateModelException

Gets a TemplateModel from the hash.

Specified by:

get in interface freemarker.template.TemplateHashModel

Parameters:

key - the name by which the TemplateModel is identified in the template.

Returns:

the TemplateModel referred to by the key, or null if not found.

Throws:

freemarker.template.TemplateModelException

isEmpty

public boolean isEmpty()
                throws freemarker.template.TemplateModelException

Specified by:

isEmpty in interface freemarker.template.TemplateHashModel

Throws:

freemarker.template.TemplateModelException

getAdaptedObject

public Object getAdaptedObject(Class hint)

Retrieves the underlying object, or some other object semantically equivalent to its value narrowed by the class hint.

Specified by:

getAdaptedObject in interface freemarker.template.AdapterTemplateModel

Parameters:

hint - the desired class of the returned value. An implementation should make reasonable effort to retrieve an object of the requested class, but if that is impossible, it must at least return the underlying object as-is. As a minimal requirement, an implementation must always return the exact underlying object when hint.isInstance(underlyingObject) == true holds. When called with java.lang.Object.class, it should return a generic Java object (i.e. if the model is wrapping a scripting lanugage object that is further wrapping a Java object, the deepest underlying Java object should be returned).

Returns:

the underlying object, or its value accommodated for the hint class.
