Class FromStringValueConverter<T>

java.lang.Object
com.soklet.converter.AbstractValueConverter<String,T>
com.soklet.converter.FromStringValueConverter<T>
All Implemented Interfaces:
ValueConverter<String,T>
@ThreadSafe public abstract class FromStringValueConverter<T> extends AbstractValueConverter<String,T>
Convenience superclass which provides default implementations of ValueConverter methods that convert from String to other types.

For example: 

 public record Jwt(
  String header,
  String payload,
  String signature
) {}

ValueConverter<String, Jwt> jwtVc = new FromStringValueConverter<>() {
  @Nonnull
  public Optional<Jwt> performConversion(@Nullable String from) throws Exception {
    if(from == null)
      return Optional.empty();

    // JWT is of the form "a.b.c", break it into pieces
    String[] components = from.split("\\.");
    Jwt jwt = new Jwt(components[0], components[1], components[2]);
    return Optional.of(jwt);
  }
};
