Class BaseDynaBeanMapDecorator<K>
- Type Parameters:
- K- the type of the keys in the decorated map
- Direct Known Subclasses:
- DynaBeanPropertyMapDecorator
 A base class for decorators providing Map behavior on DynaBeans.
 
 The motivation for this implementation is to provide access to DynaBean properties in technologies that are unaware of BeanUtils and
 DynaBeans - such as the expression languages of JSTL and JSF.
 
 This rather technical base class implements the methods of the Map interface on top of a DynaBean. It was introduced to handle generic
 parameters in a meaningful way without breaking backwards compatibility of the 1.x DynaBeanMapDecorator class: A map wrapping a DynaBean
 should be of type Map<String, Object>. However, when using these generic parameters in DynaBeanMapDecorator this would be an incompatible
 change (as method signatures would have to be adapted). To solve this problem, this generic base class is added which allows specifying the key type as
 parameter. This makes it easy to have a new subclass using the correct generic parameters while DynaBeanMapDecorator could still remain with
 compatible parameters.

Method Details- 
clearclear() operation is not supported.- Specified by:
- clearin interface- Map<K,- Object> 
- Throws:
- UnsupportedOperationException- This operation is not yet supported
 
- 
containsKeyIndicate whether theDynaBeancontains a specified value for one (or more) of its properties.
- 
containsValueIndicates whether the decoratedDynaBeancontains a specified value.- Specified by:
- containsValuein interface- Map<K,- Object> 
- Parameters:
- value- The value to check for.
- Returns:
- trueif one of the- DynaBean's properties contains the specified value, otherwise- false.
 
- 
convertKeyConverts the name of a property to the key type of this decorator.- Parameters:
- propertyName- the name of a property
- Returns:
- the converted key to be used in the decorated map
 
- 
entrySetReturns the Set of the property/value mappings in the decorated DynaBean.Each element in the Set is a Map.Entrytype.
- 
getGets the value for the specified key from the decoratedDynaBean.
- 
getDynaBeanProvide access to the underlyingDynaBeanthis Map decorates.- Returns:
- the decorated DynaBean.
 
- 
isEmptyIndicate whether the decoratedDynaBeanhas any properties.
- 
isReadOnlyIndicate whether the Map is read only.- Returns:
- trueif the Map is read only, otherwise- false.
 
- 
keySetReturns the Set of the property names in the decorated DynaBean.N.B.For DynaBeans whose associatedDynaClassis aMutableDynaClassa new Set is created every time, otherwise the Set is created only once and cached.
