Method Detail

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

getTypeMatcher

public Matcher<? super TypeLiteral<?>> getTypeMatcher()

getTypeConverter

public TypeConverter getTypeConverter()
