Class ImmutableClassToInstanceMap.Builder<B>

java.lang.Object
  extended by com.google.common.collect.ImmutableClassToInstanceMap.Builder<B>
Enclosing class:
ImmutableClassToInstanceMap<B>

public static final class ImmutableClassToInstanceMap.Builder<B>
extends Object

A builder for creating immutable class-to-instance maps. Example:

   static final ImmutableClassToInstanceMap<Handler> HANDLERS =
       new ImmutableClassToInstanceMap.Builder<Handler>()
           .put(FooHandler.class, new FooHandler())
           .put(BarHandler.class, new SubBarHandler())
           .put(Handler.class, new QuuxHandler())
           .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:
2.0 (imported from Google Collections Library)

Method Detail

put

public <T extends B> ImmutableClassToInstanceMap.Builder<B> put(Class<T> key,
                                                                T value)
Associates key with value in the built map. Duplicate keys are not allowed, and will cause build() to fail.


putAll

public <T extends B> ImmutableClassToInstanceMap.Builder<B> putAll(Map<? extends Class<? extends T>,? extends T> map)
Associates all of map's keys and values in the built map. Duplicate keys are not allowed, and will cause build() to fail.

Throws:
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

build

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

Throws:
IllegalArgumentException - if duplicate keys were added
