Method Summary

Modifier and Type	Method and Description
protected BasicBeanDescription	_findStdJdkCollectionDesc(MapperConfig<?> cfg, JavaType type, ClassIntrospector.MixInResolver r)
protected BasicBeanDescription	_findStdTypeDesc(JavaType type) Method called to see if type is one of core JDK types that we have cached for efficiency.
protected boolean	_isStdJDKCollection(JavaType type) Helper method used to decide whether we can omit introspection for members (methods, fields, constructors); we may do so for a limited number of container types JDK provides.
protected POJOPropertiesCollector	collectProperties(MapperConfig<?> config, JavaType type, ClassIntrospector.MixInResolver r, boolean forSerialization, String mutatorPrefix)
protected POJOPropertiesCollector	collectPropertiesWithBuilder(MapperConfig<?> config, JavaType type, ClassIntrospector.MixInResolver r, boolean forSerialization)
protected POJOPropertiesCollector	constructPropertyCollector(MapperConfig<?> config, AnnotatedClass ac, JavaType type, boolean forSerialization, String mutatorPrefix) Overridable method called for creating POJOPropertiesCollector instance to use; override is needed if a custom sub-class is to be used.
BasicBeanDescription	forClassAnnotations(MapperConfig<?> cfg, JavaType type, ClassIntrospector.MixInResolver r) Factory method that constructs an introspector that only has information regarding annotations class itself (or its supertypes) has, but nothing on methods or constructors.
BasicBeanDescription	forCreation(DeserializationConfig cfg, JavaType type, ClassIntrospector.MixInResolver r) Factory method that constructs an introspector that has information necessary for creating instances of given class ("creator"), as well as class annotations, but no information on member methods
BasicBeanDescription	forDeserialization(DeserializationConfig cfg, JavaType type, ClassIntrospector.MixInResolver r) Factory method that constructs an introspector that has all information needed for deserialization purposes.
BasicBeanDescription	forDeserializationWithBuilder(DeserializationConfig cfg, JavaType type, ClassIntrospector.MixInResolver r) Factory method that constructs an introspector that has all information needed for constructing deserializers that use intermediate Builder objects.
BasicBeanDescription	forDirectClassAnnotations(MapperConfig<?> cfg, JavaType type, ClassIntrospector.MixInResolver r) Factory method that constructs an introspector that only has information regarding annotations class itself has (but NOT including its supertypes), but nothing on methods or constructors.
BasicBeanDescription	forSerialization(SerializationConfig cfg, JavaType type, ClassIntrospector.MixInResolver r) Factory method that constructs an introspector that has all information needed for serialization purposes.
