mappings

protected HashMap<String,Map<String,Object>> mappings

Target class conversion Mappings.

 Map>
  - Class -> convert to class
  - Map
    - String -> property name
                eg. Element_property, property etc.
    - Object -> String to represent properties
                eg. value part of
                    KeyProperty_property=id
             -> TypeConverter to represent an Ognl TypeConverter
                eg. value part of
                    property=foo.bar.MyConverter
             -> Class to represent a class
                eg. value part of
                    Element_property=foo.bar.MyObject
 

noMapping

protected LinkedHashSet<String> noMapping

Unavailable target class conversion mappings, serves as a simple cache.

defaultMappings

protected HashMap<String,ognl.TypeConverter> defaultMappings

Record class and its type converter mapping.

 - String - classname as String
 - TypeConverter - instance of TypeConverter
 

unknownMappings

protected LinkedHashSet<String> unknownMappings

Record classes that doesn't have conversion mapping defined.

 - String -> classname as String

                           Object o,
                           Class aClass)

覆盖:

convertValue 在类中 ognl.DefaultTypeConverter

convertValue

public Object convertValue(Map context,
                           Object target,
                           Member member,

                           Class toClass)

Convert value from one form to another. Minimum requirement of arguments:

• supplying context, toClass and value
• supplying context, target and value.

指定者:

convertValue 在接口中 ognl.TypeConverter

覆盖:
