Method Detail

getInstance

@Nullable
public <T extends B> 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>

putInstance

@Nullable
public <T extends B> T putInstance(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:

getInstance in interface TypeToInstanceMap<B>

putInstance

@Nullable
public <T extends B> T putInstance(TypeToken<T> type,
                                   @Nullable
                                   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.

put

public B put(TypeToken<? extends B> key,
             B value)

Not supported. Use putInstance(java.lang.Class<T>, T) instead.

Specified by:

put in interface Map<TypeToken<? extends B>,B>

Overrides:

put in class ForwardingMap<TypeToken<? extends B>,B>

putAll

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

Not supported. Use putInstance(java.lang.Class<T>, T) instead.

Specified by:

putAll in interface Map<TypeToken<? extends B>,B>

Overrides:

putAll in class ForwardingMap<TypeToken<? extends B>,B>

entrySet

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

Specified by:

entrySet in interface Map<TypeToken<? extends B>,B>

Overrides:

entrySet in class ForwardingMap<TypeToken<? extends B>,B>
