java.lang.Object
- com.google.inject.spi.Message

All Implemented Interfaces:

Element, Serializable
```
public final class Message
extends Object
implements Serializable, Element
```
An error message and the context in which it occured. Messages are usually created internally by Guice and its extensions. Messages can be created explicitly in a module using addError() statements:
```
     try {
       bindPropertiesFromFile();
     } catch (IOException e) {
       addError(e);
     }
```

    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.

  - 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
