All Implemented Interfaces:

Converter

public class AggregateConverter

canConvert

public boolean canConvert(Object fromValue,
                          ReifiedType toType)

Description copied from interface: Converter

Return if this converter is able to convert the specified object to the specified type.

Specified by:

canConvert in interface Converter

Parameters:

fromValue - The source object s to convert.

toType - The target type T.

Returns:

true if the conversion is possible, false otherwise.

convert

public Object convert(Object fromValue,
                      ReifiedType type)
               throws Exception

Description copied from interface: Converter

Convert the specified object to an instance of the specified type.

Specified by:

convert in interface Converter

Parameters:

fromValue - The source object s to convert.

type - The target type T.

Returns:

An instance with a type that is assignable from targetType's raw class

Throws:

Exception - If the conversion cannot succeed. This exception should not be thrown when the canConvert method has returned true.
