Uses of Class
com.fasterxml.jackson.databind.util.LRUMap

Packages that use LRUMap

Package	Description
com.fasterxml.jackson.databind.deser	Contains implementation classes of deserialization part of data binding.
com.fasterxml.jackson.databind.introspect	Functionality needed for Bean introspection, required for detecting accessors and mutators for Beans, as well as locating and handling method annotations.
com.fasterxml.jackson.databind.type	Package that contains concrete implementations of JavaType, as well as the factory (TypeFactory) for constructing instances from various input data types (like Class, Type) and programmatically (for structured types, arrays, Lists and Maps).
com.fasterxml.jackson.databind.util	Utility classes for Mapper package.

Uses of LRUMap in com.fasterxml.jackson.databind.deser

Fields in com.fasterxml.jackson.databind.deser declared as LRUMap

Modifier and Type	Field and Description
protected LRUMap<JavaType,JsonDeserializer<Object>>	DeserializerCache._cachedDeserializers We will also cache some dynamically constructed deserializers; specifically, ones that are expensive to construct.

Uses of LRUMap in com.fasterxml.jackson.databind.introspect

Fields in com.fasterxml.jackson.databind.introspect declared as LRUMap

Modifier and Type	Field and Description
protected LRUMap<Class<?>,Boolean>	JacksonAnnotationIntrospector._annotationsInside Since introspection of annotation types is a performance issue in some use cases (rare, but do exist), let's try a simple cache to reduce need for actual meta-annotation introspection.
