Class StaticInjectionRequest

java.lang.Object
org.elasticsearch.common.inject.spi.StaticInjectionRequest
All Implemented Interfaces:
Element

public final class StaticInjectionRequest
extends java.lang.Object
implements Element
A request to inject the static fields and methods of a type. Requests are created explicitly in a module using requestStaticInjection() statements:
     requestStaticInjection(MyLegacyService.class);
Since:
2.0
  • Method Summary

    Modifier and Type Method Description
    <T> T acceptVisitor​(ElementVisitor<T> visitor)
    Accepts an element visitor.
    void applyTo​(Binder binder)
    Writes this module element to the given binder (optional operation).
    java.util.Set<InjectionPoint> getInjectionPoints()
    Returns the static methods and fields of type that will be injected to fulfill this request.
    java.lang.Object getSource()
    Returns an arbitrary object containing information about the "place" where this element was configured.
    java.lang.Class<?> getType()  

    Methods inherited from class java.lang.Object

    clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait
  • Method Details

    • getSource

      public java.lang.Object getSource()
      Description copied from interface: Element
      Returns an arbitrary object containing information about the "place" where this element was configured. Used by Guice in the production of descriptive error messages.

      Tools might specially handle types they know about; StackTraceElement is a good example. Tools should simply call toString() on the source object if the type is unfamiliar.

      Specified by:
      getSource in interface Element
    • getType

      public java.lang.Class<?> getType()
    • getInjectionPoints

      public java.util.Set<InjectionPoint> getInjectionPoints() throws ConfigurationException
      Returns the static methods and fields of type that will be injected to fulfill this request.
      Returns:
      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 type, such as a field with multiple binding annotations. The exception's partial value is a Set<InjectionPoint> of the valid injection points.
    • applyTo

      public void applyTo​(Binder binder)
      Description copied from interface: Element
      Writes this module element to the given binder (optional operation).
      Specified by:
      applyTo in interface Element
      Parameters:
      binder - to apply configuration element to
    • acceptVisitor

      public <T> T acceptVisitor​(ElementVisitor<T> visitor)
      Description copied from interface: Element
      Accepts an element visitor. Invokes the visitor method specific to this element's type.
      Specified by:
      acceptVisitor in interface Element
      Parameters:
      visitor - to call back on
