Interface ClassToInstanceMap<B>

Type Parameters:
B - the common supertype that all entries must share; often this is simply Object
All Superinterfaces:
Map<Class<? extends B>,B>
All Known Implementing Classes:
ImmutableClassToInstanceMap, MutableClassToInstanceMap
@GwtCompatible @Deprecated(since="2022-12-01") public interface ClassToInstanceMap<B> extends Map<Class<? extends B>,B>
Deprecated.
The Google Guava Core Libraries are deprecated and will not be part of the AEM SDK after April 2023
A map, each entry of which maps a Java raw type to an instance of that type. In addition to implementing Map, the additional type-safe operations putInstance(java.lang.Class<T>, T) and getInstance(java.lang.Class<T>) are available.

Like any other Map<Class, Object>, this map may contain entries for primitive types, and a primitive type and its corresponding wrapper type may map to different values.

See the Guava User Guide article on ClassToInstanceMap.

To map a generic type to an instance of that type, use TypeToInstanceMap instead.

Since:
2.0 (imported from Google Collections Library)

  • Method Details

    • getInstance

      <T extends B> T getInstance(Class<T> type)
      Deprecated.
      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.

    • putInstance

      <T extends B> T putInstance(Class<T> type, @Nullable T value)
      Deprecated.
      Maps the specified class to the specified value. Does not associate this value with any of the class's supertypes.
      Returns:
      the value previously associated with this class (possibly null), or null if there was no previous entry.
