Method Details

getInstance

public <T extends @NonNull B> @Nullable T getInstance(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 extends @Nullable Object>

getInstance

public <T extends @NonNull B> @Nullable 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:

getInstance in interface TypeToInstanceMap<B extends @Nullable Object>

putInstance

@CanIgnoreReturnValue
public <T extends B> @Nullable T putInstance(Class<@NonNull T> type,
 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 extends @Nullable Object>

Returns:

the value previously associated with this class (possibly null), or null if there was no previous entry.

putInstance

@CanIgnoreReturnValue
public <T extends B> @Nullable T putInstance(TypeToken<@NonNull T> type,
 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 extends @Nullable Object>

Returns:

the value previously associated with this type (possibly null), or null if there was no previous entry.

put

@CanIgnoreReturnValue
@Deprecated
public @Nullable B put(TypeToken<? extends @NonNull B> key,
 B value)

Deprecated.

unsupported operation

Not supported. Use putInstance(Class, T) instead.

Specified by:

put in interface Map<TypeToken<? extends B extends @Nullable Object>, B extends @Nullable Object>

Overrides:

put in class ForwardingMap<TypeToken<? extends @NonNull B extends @Nullable Object>, B extends @Nullable Object>

Throws:

UnsupportedOperationException - always

putAll

@Deprecated
public void putAll(Map<? extends TypeToken<? extends @NonNull B>, ? extends B> map)

Deprecated.

unsupported operation

Not supported. Use putInstance(Class, T) instead.

Specified by:

putAll in interface Map<TypeToken<? extends B extends @Nullable Object>, B extends @Nullable Object>

Overrides:

putAll in class ForwardingMap<TypeToken<? extends @NonNull B extends @Nullable Object>, B extends @Nullable Object>

Throws:

UnsupportedOperationException - always

entrySet

public Set<Map.Entry<TypeToken<? extends @NonNull B>, B>> entrySet()

Specified by:

entrySet in interface Map<TypeToken<? extends B extends @Nullable Object>, B extends @Nullable Object>

Overrides:

entrySet in class ForwardingMap<TypeToken<? extends @NonNull B extends @Nullable Object>, B extends @Nullable Object>

delegate

protected Map<TypeToken<? extends @NonNull B>, B> delegate()

Description copied from class: ForwardingObject

Returns the backing delegate instance that methods are forwarded to. Abstract subclasses generally override this method with an abstract method that has a more specific return type, such as ForwardingSet.delegate(). Concrete subclasses override this method to supply the instance being decorated.

Specified by:

delegate in class ForwardingMap<TypeToken<? extends @NonNull B extends @Nullable Object>, B extends @Nullable Object>
