public <T> T acceptVisitor(ElementVisitor<T> visitor)

Implements com.google.inject.spi.Element.acceptVisitor.

Doc from com.google.inject.spi.Element.acceptVisitor.

Accepts an element visitor. Invokes the visitor method specific to this element's type.

Parameters
visitor:ElementVisitor<T>

to call back on

public Object getExposedSource(Key<?> key)

Implements com.google.inject.spi.PrivateElements.getExposedSource.

Doc from com.google.inject.spi.PrivateElements.getExposedSource.

Returns an arbitrary object containing information about the "place" where this key was exposed. 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.

Parameters
key:Key<?>

one of the keys exposed by this module.
