of
Returns an empty type to instance map. -
builder
Returns a new builder. -
getInstance
Description copied from interface:TypeToInstanceMap
Returns the value the specified type is mapped to, ornull
if no entry for this type is present. This will only return a value that was bound to this specific type, not a value that may have been bound to a subtype.- Specified by:
getInstance
in interfaceTypeToInstanceMap<B>
-
getInstance
Description copied from interface:TypeToInstanceMap
Returns the value the specified class is mapped to, ornull
if no entry for this class is present. This will only return a value that was bound to this specific class, not a value that may have been bound to a subtype.getInstance(Foo.class)
is equivalent togetInstance(TypeToken.of(Foo.class))

in interfaceTypeToInstanceMap<B>
- Returns:
- the value previously associated with this type (possibly

), ornull
if there was no previous entry. - Throws:

delegate
Description copied from class:ForwardingObject
Returns the backing delegate instance that methods are forwarded to. Abstract subclasses generally override this method with an abstract method that has a more specific return type, such asForwardingSet.delegate()
. Concrete subclasses override this method to supply the instance being decorated.- Specified by:
