After invoking build() it is still possible to add more entries and build again. Thus each map generated by this builder will be a superset of any map generated before it.

ImmutableClassToInstanceMap |
build()
Returns a new immutable class-to-instance map containing the entries provided to this builder.

<T extends B> ImmutableClassToInstanceMap |
put(Class
Associates
key with
value in the built map.
|
<T extends B> ImmutableClassToInstanceMap |
putAll(Map
Associates all of
map's keys and values in the built map.
|
public <T extends B> ImmutableClassToInstanceMap.Builder <B> put(Class <T> key, T value)
key with
value in the built map. Duplicate keys are not allowed, and will cause
build() to fail.
public <T extends B> ImmutableClassToInstanceMap.Builder <B> putAll(Map <? extends Class <? extends T> ,? extends T> map)
map's keys and values in the built map. Duplicate keys are not allowed, and will cause
build() to fail.
NullPointerException - if any key or value in
map is null
ClassCastException - if any value is not an instance of the type specified by its key
public ImmutableClassToInstanceMap<B> build()
IllegalArgumentException - if duplicate keys were added
