Method Detail

setDefaultObjectWrapper

public static void setDefaultObjectWrapper(ObjectWrapper objectWrapper)

Sets the default object wrapper that is used when a wrapping template model is constructed without being passed an explicit object wrapper. The default value is ObjectWrapper.SIMPLE_WRAPPER. Note that Configuration.setSharedVariable(String, Object) and Template.process(Object, java.io.Writer) don't use this setting, they rather use whatever object wrapper their Configurable.getObjectWrapper() method returns.

getDefaultObjectWrapper

public static ObjectWrapper getDefaultObjectWrapper()

Returns the default object wrapper that is used when a wrapping template model is constructed without being passed an explicit object wrapper. Note that Configuration.setSharedVariable(String, Object) and Template.process(Object, java.io.Writer) don't use this setting, they rather use whatever object wrapper their Configurable.getObjectWrapper() method returns.

getObjectWrapper

public ObjectWrapper getObjectWrapper()

Returns the object wrapper instance used by this wrapping template model.

setObjectWrapper

public void setObjectWrapper(ObjectWrapper objectWrapper)

wrap

protected final TemplateModel wrap(java.lang.Object obj)
                            throws TemplateModelException

Wraps the passed object into a template model using this object's object wrapper.

Parameters:

obj - the object to wrap

Returns:

the template model that wraps the object
