MapModel
public class MapModel extends StringModel implements TemplateMethodModelEx(Code)

A special case of BeanModel that adds implementation for TemplateMethodModelEx on map objects that is a shortcut for the Map.get() method. Note that if the passed argument itself is a reflection-wrapper model, then the map lookup will be performed using the wrapped object as the key. Note that you can call get() using the map.key syntax inherited from BeanModel as well, however in that case the key is always a string.

The class itself does not implement the freemarker.template.TemplateCollectionModel . You can, however use map.entrySet(), map.keySet(), or map.values() to obtain freemarker.template.TemplateCollectionModel instances for various aspects of the map.

Field Summary
final static  ModelFactoryFACTORY
    

Constructor Summary
public  MapModel(Map map, BeansWrapper wrapper)
     Creates a new model that wraps the specified map object.
Parameters:
  map - the map object to wrap into a model.
Parameters:
  wrapper - the BeansWrapper associated with this model.Every model has to have an associated BeansWrapper instance.

Method Summary
public  Objectexec(List arguments)
     The first argument is used as a key to call the map's get method.
protected  TemplateModelinvokeGenericGet(Map keyMap, Class clazz, String key)
     Overridden to invoke the generic get method by casting to Map instead of through reflection - should yield better performance.
public  booleanisEmpty()
    
protected  SetkeySet()
    
public  intsize()

Constructor Detail
MapModel
public MapModel(Map map, BeansWrapper wrapper)(Code)
Creates a new model that wraps the specified map object.
Parameters:
  map - the map object to wrap into a model.
Parameters:
  wrapper - the BeansWrapper associated with this model.Every model has to have an associated BeansWrapper instance. Themodel gains many attributes from its wrapper, including the caching behavior, method exposure level, method-over-item shadowing policy etc.




Method Detail
exec
public Object exec(List arguments) throws TemplateModelException(Code)
The first argument is used as a key to call the map's get method.



invokeGenericGet
protected TemplateModel invokeGenericGet(Map keyMap, Class clazz, String key) throws TemplateModelException(Code)
Overridden to invoke the generic get method by casting to Map instead of through reflection - should yield better performance.



isEmpty
public boolean isEmpty()(Code)



keySet
protected Set keySet()(Code)



size
public int size()(Code)
