Method Summary

Methods
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.
