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

Description copied from interface: Converter

Convert the provided source object argument to an instance of the specified target class.

Specified by:

convertSourceToTargetClass in interface Converter

Parameters:

source - the source object to convert, which must be an instance of Converter.getSourceClass()

targetClass - the target class to convert the source to, which must be equal to or a specialization of Converter.getTargetClass()
