Constructor Detail

PropertySupport.Reflection

public PropertySupport.Reflection(Object instance,
                                  Class valueType,
                                  Method getter,
                                  Method setter)

Create a support with method objects specified. The methods must be public.

Parameters:: instance - (Bean) object to work on; valueType - type of the property; getter - getter method, can be null; setter - setter method, can be null
Throws:: IllegalArgumentException - if the methods are not public

PropertySupport.Reflection

public PropertySupport.Reflection(Object instance,
                                  Class valueType,
                                  String getter,
                                  String setter)
                           throws NoSuchMethodException

Create a support with methods specified by name. The instance class will be examined for the named methods. But if the instance class is not public, the nearest public superclass will be used instead, so that the getters and setters remain accessible.

Parameters:: instance - (Bean) object to work on; valueType - type of the property; getter - name of getter method, can be null; setter - name of setter method, can be null
Throws:: NoSuchMethodException - if the getter or setter methods cannot be found

PropertySupport.Reflection

public PropertySupport.Reflection(Object instance,
                                  Class valueType,
                                  String property)
                           throws NoSuchMethodException

Create a support based on the property name. The getter and setter methods are constructed by capitalizing the first letter in the name of propety and prefixing it with get and set, respectively.

Parameters:: instance - object to work on; valueType - type of the property; property - name of property
Throws:: NoSuchMethodException - if the getter or setter methods cannot be found
