import static;


import java.util.Set;

 * A request to inject the static fields and methods of a type. Requests are created
 * explicitly in a module using {@link[])
 * requestStaticInjection()} statements:
 * <pre>
 *     requestStaticInjection(MyLegacyService.class);</pre>
 * @author (Jesse Wilson)
 * @since 2.0
public final class StaticInjectionRequest implements Element {
  private final Object source;
  private final Class<?> type;

  StaticInjectionRequest(Object source, Class<?> type) {
    this.source = checkNotNull(source, "source");
    this.type = checkNotNull(type, "type");

  public Object getSource() {
    return source;

  public Class<?> getType() {
    return type;

   * Returns the static methods and fields of {@code type} that will be injected to fulfill this
   * request.
   * @return a possibly empty set of injection points. The set has a specified iteration order. All
   *      fields are returned and then all methods. Within the fields, supertype fields are returned
   *      before subtype fields. Similarly, supertype methods are returned before subtype methods.
   * @throws ConfigurationException if there is a malformed injection point on {@code type}, such as
   *      a field with multiple binding annotations. The exception's {@link
   *      ConfigurationException#getPartialValue() partial value} is a {@code Set<InjectionPoint>}
   *      of the valid injection points.
  public Set<InjectionPoint> getInjectionPoints() throws ConfigurationException {
    return InjectionPoint.forStaticMethodsAndFields(type);

  public void applyTo(Binder binder) {

  public <T> T acceptVisitor(ElementVisitor visitor) {
    return visitor.visit(this);
