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

Packages that use LRUMap

Package	Description
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.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.
protected LRUMap<JavaType,BasicBeanDescription>	BasicClassIntrospector._cachedFCA Looks like 'forClassAnnotations()' gets called so frequently that we should consider caching to avoid some of the lookups.

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

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

Modifier and Type	Field and Description
protected LRUMap<Object,JavaType>	TypeFactory._typeCache Since type resolution can be expensive (specifically when resolving actual generic types), we will use small cache to avoid repetitive resolution of core types

Methods in com.fasterxml.jackson.databind.type with parameters of type LRUMap

Modifier and Type	Method and Description
TypeFactory	TypeFactory.withCache(LRUMap<Object,JavaType> cache) Mutant factory method that will construct new TypeFactory with identical settings except for different cache; most likely one with bigger maximum size.

Constructors in com.fasterxml.jackson.databind.type with parameters of type LRUMap

Constructor and Description
TypeFactory(LRUMap<Object,JavaType> typeCache)
TypeFactory(LRUMap<Object,JavaType> typeCache, TypeParser p, TypeModifier[] mods, ClassLoader classLoader)

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

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

Modifier and Type	Field and Description
protected LRUMap<ClassKey,PropertyName>	RootNameLookup._rootNames For efficient operation, let's try to minimize number of times we need to introspect root element name to use.
