Class ConversionRequest

java.lang.Object

org.scijava.convert.ConversionRequest

public class ConversionRequest
extends Object

Currency for use in Converter and ConvertService methods.

ConversionRequest(java.lang.Object, java.lang.reflect.Type, java.lang.reflect.Type) provides a variety of constructors. Note that only one destination type needs to be set (e.g. either a Type or a Class).

Only the Class source needs to be set for Converter lookup, such as through HandlerService.getHandler(Object). However, to perform an actual conversion, e.g. using Converter.convert(ConversionRequest), you must provide an Object source.

NB: once a Converter has been acquired, the ConversionRequest used for lookup can be reused to cast to the same destination type, simply by updating the source object using the setSourceObject(Object) method.
