All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`convertClassNamesToClasses(ClassLoader classLoader)`	INTERNAL: Convert all the class-name-based settings in this converter to actual class-based settings.
`Object`	`convertDataValueToObjectValue(Object fieldValue, Session session)`	INTERNAL: The field value must first be converted to the field type, then the attribute type.
`Object`	`convertObjectValueToDataValue(Object attributeValue, Session session)`	INTERNAL: Convert to the field class.
`Class`	`getDataClass()`	PUBLIC: Returns the class type of the data value.
`String`	`getDataClassName()`	INTERNAL: Return the name of the data type for the MW usage.
`Class`	`getObjectClass()`	PUBLIC: Returns the class type of the object value.
`String`	`getObjectClassName()`	INTERNAL: Return the name of the object type for the MW usage.
`void`	`initialize(DatabaseMapping mapping, Session session)`	INTERNAL: Set the mapping.
`boolean`	`isMutable()`	INTERNAL: If the converter converts the value to a non-atomic value, i.e.
`void`	`setDataClass(Class dataClass)`	PUBLIC: Set the class type of the data value.
`void`	`setDataClassName(String dataClassName)`	INTERNAL: Set the name of the data type for the MW usage.
`void`	`setObjectClass(Class objectClass)`	PUBLIC: Set the class type of the object value.

  - convertClassNamesToClasses
```
public void convertClassNamesToClasses(ClassLoader classLoader)
```
    INTERNAL: Convert all the class-name-based settings in this converter to actual class-based settings. This method is used when converting a project that has been built with class names to a project with classes. This method is implemented by subclasses as necessary.

  - getObjectClass
```
public Class getObjectClass()
```
    PUBLIC: Returns the class type of the object value.
  - getObjectClassName
```
public String getObjectClassName()
```

  - getDataClass
```
public Class getDataClass()
```
    PUBLIC: Returns the class type of the data value.
  - getDataClassName
```
public String getDataClassName()
```
    INTERNAL: Return the name of the data type for the MW usage.
  - setDataClass
```
public void setDataClass(Class dataClass)
```
    PUBLIC: Set the class type of the data value.
  - setDataClassName
```
public void setDataClassName(String dataClassName)
```
    INTERNAL: Set the name of the data type for the MW usage.

```
public Object convertObjectValueToDataValue(Object attributeValue,
                                            Session session)
```
    INTERNAL: Convert to the field class.
    
    Specified by:
    
    convertObjectValueToDataValue in interface Converter
    
    Specified by:
    
    convertObjectValueToDataValue in interface CoreConverter<DatabaseMapping,Session>
  - initialize
```
public void initialize(DatabaseMapping mapping,
                       Session session)
```
    INTERNAL: Set the mapping.

    initialize in interface Converter
    
    Specified by:
    
    initialize in interface CoreConverter<DatabaseMapping,Session>
  - isMutable
```
public boolean isMutable()
```
    INTERNAL: If the converter converts the value to a non-atomic value, i.e. a value that can have its' parts changed without being replaced, then it must return false, serialization can be non-atomic.
    
    Specified by:
    
    isMutable in interface Converter
