Class DeepUnwrap

public static Object premissiveUnwrap(TemplateModel model)
            throws TemplateModelException

Same as unwrap(TemplateModel), but it doesn't throw exception if it doesn't know how to unwrap the object, but returns it as is.

public static Object unwrap(TemplateModel model)
            throws TemplateModelException

Unwraps TemplateModel-s recursively. The converting of the TemplateModel object happens with the following rules:

1. If the object implements AdapterTemplateModel, then the result of AdapterTemplateModel.getAdaptedObject(Class) for Object.class is returned.
2. If the object implements WrapperTemplateModel, then the result of WrapperTemplateModel.getWrappedObject() is returned.
3. If the object implements TemplateScalarModel, then the result of TemplateScalarModel.getAsString() is returned.
4. If the object implements TemplateNumberModel, then the result of TemplateNumberModel.getAsNumber() is returned.
5. If the object implements TemplateDateModel, then the result of TemplateDateModel.getAsDate() is returned.
6. If the object implements TemplateBooleanModel, then the result of TemplateBooleanModel.getAsBoolean() is returned.
7. If the object implements TemplateSequenceModel or TemplateCollectionModel, then a java.util.ArrayList is constructed from the subvariables, and each subvariable is unwrapped with the rules described here (recursive unwrapping).
8. If the object implements TemplateHashModelEx, then a java.util.HashMap is constructed from the subvariables, and each subvariable is unwrapped with the rules described here (recursive unwrapping).
9. Throw a TemplateModelException, because it doesn't know how to unwrapp the object.
