Package org.apache.velocity.util.introspection

Interface ConversionHandler

@Deprecated public interface ConversionHandler
Deprecated.
use TypeConversionHandler
A conversion handler adds admissible conversions between Java types whenever Velocity introspection has to map VTL methods and property accessors to Java methods. Both methods must be consistent: getNeededConverter must not return null whenever isExplicitlyConvertible returned true with the same arguments.
