public class SimpleMapModel extends WrappingTemplateModel implements TemplateHashModelEx, TemplateMethodModelEx, AdapterTemplateModel, WrapperTemplateModel
BeansWrapper
when simpleMapWrapper
mode is enabled. Provides a simple hash model interface to the
underlying map (does not copy like SimpleHash
),
and a method interface to non-string keys.NOTHING

to operate on POJOs, it can use the static utility methods in the DeepUnwrap
class to easily obtain them. However, unwrapping is not always possible (or not perfectly), and isn't always
efficient, so it's recommended to use the original TemplateModel
value as much as possible.null

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 language object that is
further wrapping a Java object, the deepest underlying Java object should
be returned).public java.lang.Object getWrappedObject()
