## Class SimpleMixInResolver

- java.lang.Object
- - com.fasterxml.jackson.databind.introspect.SimpleMixInResolver

- All Implemented Interfaces:
    ClassIntrospector.MixInResolver, java.io.Serializable

      public class SimpleMixInResolver
      extends java.lang.Object
      implements ClassIntrospector.MixInResolver, java.io.Serializable

  Simple implementation of `ClassIntrospector.MixInResolver` that just uses a `Map` for containing mapping from target to mix-in classes.

  Implementation is only thread-safe after initialization (that is, when underlying Map is not modified but only read).

  Since:
    2.6

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `void` | `addLocalDefinition(java.lang.Class<?> target, java.lang.Class<?> mixinSource)`
    `SimpleMixInResolver` | `copy()` Method called to create a new, non-shared copy, to be used by different `ObjectMapper` instance, and one that should not be connected to this instance, if resolver has mutable state.
    `java.lang.Class<?>` | `findMixInClassFor(java.lang.Class<?> cls)` Method that will check if there are "mix-in" classes (with mix-in annotations) for given class
    `int` | `localSize()`
    `void` | `setLocalDefinitions(java.util.Map<java.lang.Class<?>,java.lang.Class<?>> sourceMixins)`
    `SimpleMixInResolver` | `withoutLocalDefinitions()` Mutant factory method that constructs a new instance that has no locally defined mix-in/target mappings.
    `SimpleMixInResolver` | `withOverrides(ClassIntrospector.MixInResolver overrides)` Mutant factory for constructor a new resolver instance with given mix-in resolver override.
