public static final class ImmutableTypeToInstanceMap.Builder<B> extends java.lang.Object
A builder for creating immutable type-to-instance maps. Example:static final ImmutableTypeToInstanceMap<Handler<?>> HANDLERS = ImmutableTypeToInstanceMap.<Handler<?>>builder() .put(new TypeToken<Handler<Foo>>() {}, new FooHandler()) .put(new TypeToken<Handler<Bar>>() {}, new SubBarHandler()) .build();
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.- Since:
- 13.0
