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
  - getType
```
public TypeLiteral<T> getType()
```
    Gets the type containing the members to be injected.
  - 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
  - initializeDelegate
```
public void initializeDelegate(MembersInjector<T> delegate)
```
    Sets the actual members injector.
    
    Throws:
    
    IllegalStateException - if the delegate is already set
  - 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
  - getDelegate
```
public MembersInjector<T> getDelegate()
```
    Returns the delegate members injector, or null if it has not yet been initialized. The delegate will be initialized when this element is processed, or otherwise used to create an injector.
  - getMembersInjector
```
public MembersInjector<T> getMembersInjector()
```
    Returns the looked up members injector. The result is not valid until this lookup has been initialized, which usually happens when the injector is created. The members injector will throw an IllegalStateException if you try to use it beforehand.
