Class InjectionRequest<T>

All Implemented Interfaces:

public final class InjectionRequest<T> extends Object implements Element
A request to inject the instance fields and methods of an instance. Requests are created explicitly in a module using requestInjection() statements:
  • Constructor Details

  • Method Details

    • getSource

      public 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
    • getInstance

      public T getInstance()
    • getType

      public TypeLiteral<T> getType()
    • getInjectionPoints

      public Set<InjectionPoint> getInjectionPoints() throws ConfigurationException
      Returns the instance methods and fields of instance that will be injected to fulfill this request.
      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.
      ConfigurationException - if there is a malformed injection point on the class of instance, such as a field with multiple binding annotations. The exception's partial value is a Set<InjectionPoint> of the valid injection points.
    • acceptVisitor

      public <R> R acceptVisitor(ElementVisitor<R> 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
      visitor - to call back on
    • 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
      binder - to apply configuration element to
