Package	Description
com.fasterxml.jackson.databind	Basic data binding (mapping) functionality that allows for reading JSON content into Java Objects (POJOs) and JSON Trees (JsonNode), as well as writing Java Objects and trees as JSON.
com.fasterxml.jackson.databind.util.internal	This package contains an implementation of a bounded ConcurrentMap data structure.

Class	Description
AccessPattern	Enumeration used to indicate required access pattern for providers: this can sometimes be used to optimize out dynamic calls.
Annotations	Interface that defines interface for accessing contents of a collection of annotations.
ArrayBuilders	Helper class that contains set of distinct builders for different arrays of primitive values.
ArrayBuilders.BooleanBuilder
ArrayBuilders.ByteBuilder
ArrayBuilders.DoubleBuilder
ArrayBuilders.FloatBuilder
ArrayBuilders.IntBuilder
ArrayBuilders.LongBuilder
ArrayBuilders.ShortBuilder
ArrayIterator<T>	Iterator implementation used to efficiently expose contents of an Array as read-only iterator.
BeanUtil	Helper class that contains functionality needed by both serialization and deserialization side.
ByteBufferBackedInputStream	Simple InputStream implementation that exposes currently available content of a ByteBuffer.
ByteBufferBackedOutputStream	Simple OutputStream implementation that appends content written in given ByteBuffer instance.
ClassUtil
ClassUtil.Ctor	Value class used for caching Constructor declarations; used because caching done by JDK appears to be somewhat inefficient for some use cases.
CompactStringObjectMap	Specialized lookup class that implements functionality similar to Map, but for special case of key always being String and using more compact (and memory-access friendly) hashing scheme.
Converter<IN,OUT>	Helper interface for things that convert Objects of one type to another.
Converter.None	This marker class is only to be used with annotations, to indicate that no converter is to be used.
EnumResolver	Helper class used to resolve String values (either JSON Object field names or regular String values) into Java Enum instances.
EnumValues	Helper class used for storing String serializations of Enums, to match to/from external representations.
ExceptionUtil	Utility methods for dealing with exceptions/throwables
IgnorePropertiesUtil
IgnorePropertiesUtil.Checker	Helper class to encapsulate logic from static shouldIgnore method of util class.
ISO8601DateFormat	Deprecated. Use StdDateFormat instead
ISO8601Utils	Deprecated.
JacksonCollectors	Utility class that provides custom Collector implementations to support Stream operations.
JSONPObject	Container class that can be used to wrap any Object instances (including nulls), and will serialize embedded in JSONP wrapping.
JSONWrappedObject	General-purpose wrapper class that can be used to decorate serialized value with arbitrary literal prefix and suffix.
LinkedNode<T>	Node of a forward-only linked list.
LookupCache<K,V>	An interface describing the required API for the Jackson-databind Type cache.
LRUMap<K,V>	Helper for simple bounded maps used for reusing lookup values.
Named	Simple tag interface mostly to allow sorting by name.
NameTransformer	Helper class used to encapsulate details of name mangling, transforming of names using different strategies (prefixes, suffixes).
NameTransformer.Chained
NameTransformer.NopTransformer
NativeImageUtil	Utilities for graal native image support; mostly to improve error message handling in case of missing information for native image.
ObjectBuffer	Helper class to use for constructing Object arrays by appending entries to create arrays of various lengths (length that is not known a priori).
PrimitiveArrayBuilder<T>	Base class for specialized primitive array builders.
RawValue	Helper class used to encapsulate "raw values", pre-encoded textual content that can be output as opaque value with no quoting/escaping, using JsonGenerator.writeRawValue(String).
RootNameLookup	Helper class for caching resolved root names.
SimpleBeanPropertyDefinition	Simple immutable BeanPropertyDefinition implementation that can be wrapped around a AnnotatedMember that is a simple accessor (getter) or mutator (setter, constructor parameter) (or both, for fields).
StdConverter<IN,OUT>	Standard implementation of Converter that supports explicit type access, instead of relying type detection of generic type parameters.
StdDateFormat	Jackson's internal DateFormat implementation used by standard Date serializers and deserializers to implement default behavior: does NOT fully implement all aspects expected by DateFormat and as a consequence SHOULD NOT to be used by code outside core Jackson databind functionality.
TokenBuffer	Utility class used for efficient storage of JsonToken sequences, needed for temporary buffering.
TokenBuffer.Parser
TokenBuffer.Segment	Individual segment of TokenBuffer that can store up to 16 tokens (limited by 4 bits per token type marker requirement).
TokenBufferReadContext	Implementation of JsonStreamContext used by TokenBuffer to link back to the original context to try to keep location information consistent between source location and buffered content when it's re-read from the buffer.
TypeKey	Key that offers two "modes"; one with raw class, as used for cases were raw class type is available (for example, when using runtime type); and one with full generics-including.
ViewMatcher	Helper class used for checking whether a property is visible in the active view
