      • getInstance

        @Nullable
public <T extends B> T getInstance​(java.lang.Class<T> type)
        Description copied from interface: TypeToInstanceMap
        Returns the value the specified class is mapped to, or null 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 to getInstance(TypeToken.of(Foo.class)).

        Specified by:
        getInstance in interface TypeToInstanceMap<B>

      • putInstance

        @Nullable
public <T extends B> T putInstance​(java.lang.Class<T> type,
                                   @Nullable
                                   T value)
        Description copied from interface: TypeToInstanceMap
        Maps the specified class to the specified value. Does not associate this value with any of the class's supertypes.

        putInstance(Foo.class, foo) is equivalent to putInstance(TypeToken.of(Foo.class), foo).

        Specified by:
        putInstance in interface TypeToInstanceMap<B>
        Returns:
        the value previously associated with this class (possibly null), or null if there was no previous entry.

      • getInstance

        @Nullable
public <T extends B> T getInstance​(TypeToken<T> type)
        Description copied from interface: TypeToInstanceMap
        Returns the value the specified type is mapped to, or null 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:

                                   T value)
        Description copied from interface: TypeToInstanceMap
        Maps the specified type to the specified value. Does not associate this value with any of the type's supertypes.
        Specified by:
        putInstance in interface TypeToInstanceMap<B>
        Returns:
        the value previously associated with this type (possibly null), or null if there was no previous entry.
