Specified by:

getSourceClass in interface Converter

Returns:

the source type

getTargetClass

public final java.lang.Class<?> getTargetClass()

Description copied from interface: Converter

The target class this converter can convert to. May be an interface or abstract type to allow this converter to convert specific subclasses as well.

Specified by:

getTargetClass in interface Converter

Returns:

the target type

convertSourceToTargetClass

public final java.lang.Object convertSourceToTargetClass(java.lang.Object source,
                                          java.lang.Class<?> targetClass)
