Class ImmutableTypeToInstanceMap.Builder<B>

java.lang.Object

net.tribe7.common.reflect.ImmutableTypeToInstanceMap.Builder<B>

Enclosing class:

ImmutableTypeToInstanceMap<B>

@Beta
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

Method Detail

put

public <T extends B> ImmutableTypeToInstanceMap.Builder<B> put(java.lang.Class<T> key,
                                                      T value)

Associates key with value in the built map. Duplicate keys are not allowed, and will cause build() to fail.

put

public <T extends B> ImmutableTypeToInstanceMap.Builder<B> put(TypeToken<T> key,
                                                      T value)

Associates key with value in the built map. Duplicate keys are not allowed, and will cause build() to fail.

build

public ImmutableTypeToInstanceMap<B> build()

Returns a new immutable type-to-instance map containing the entries provided to this builder.

Throws:

java.lang.IllegalArgumentException - if duplicate keys were added
