Package org.jdbi.v3.core.interceptor

Interface JdbiInterceptor<S,T>

Type Parameters:
S - Transformation source type.
T - Type of the transformation result.
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@Alpha @FunctionalInterface public interface JdbiInterceptor<S,T>
Generic interface to allow transformation operation interception. Used to manage the various inferred data types that may need special treatment.

    Description
    T
    intercept(S source, JdbiInterceptionChain<T> chain)
    Process a given source object.

    • intercept

      @Nullable @CheckReturnValue T intercept(@Nullable S source, JdbiInterceptionChain<T> chain)
      Process a given source object.
      • If the interceptor wants to process the object, return the result directly.
      • If the interceptor passes on processing, it must return JdbiInterceptionChain.next()
      
  class SomeInterceptor implements JdbiInterceptor<Foo, Bar> {
      @Override
      public Bar intercept(Foo source, JdbiInterceptionChain<Foo, Bar> chain) {
          if (source != null && source.isBarCompatible()) {
              return new Bar(source);
          } else {
              return chain.next();
          }
      }
  }
      Parameters:
      source - A source object.
      Returns:
      The destination type.
