• Interface Summary 

  Interface	Description
  BufferRecycler.Gettable	Tag-on interface to allow various other types to expose BufferRecycler they are constructed with.
  DefaultPrettyPrinter.Indenter	Interface that defines objects that can produce indentation used to separate object entries and array values.
  Instantiatable<T>	Add-on interface used to indicate things that may be "blueprint" objects which can not be used as is, but are used for creating usable per-process (serialization, deserialization) instances, using Instantiatable.createInstance() method.
  JacksonFeature	Basic API implemented by Enums used for simple Jackson "features": on/off settings and capabilities exposed as something that can be internally represented as bit sets.
  JsonGeneratorDecorator	Simple interface to allow adding decorators around JsonGenerators.
  RecyclerPool<P extends RecyclerPool.WithPool<P>>	API for object pools that control creation and possible reuse of objects that are costly to create (often things like encoding/decoding buffers).
  RecyclerPool.WithPool<P extends RecyclerPool.WithPool<P>>	Simple add-on interface that poolable entities must implement.

• Class Summary 

  Class	Description
  BufferRecycler	This is a small utility class, whose main functionality is to allow simple reuse of raw byte/char buffers.
  BufferRecyclers	Deprecated Since 2.16 recycling aspects are handled via RecyclerPool.
  ByteArrayBuilder	Helper class that is similar to ByteArrayOutputStream in usage, but more geared to Jackson use cases internally.
  DefaultIndenter	Default linefeed-based indenter, used by DefaultPrettyPrinter (unless overridden).
  DefaultPrettyPrinter	Default PrettyPrinter implementation that uses 2-space indentation with platform-default linefeeds.
  DefaultPrettyPrinter.FixedSpaceIndenter	This is a very simple indenter that only adds a single space for indentation.
  DefaultPrettyPrinter.NopIndenter	Dummy implementation that adds no indentation whatsoever
  InternalJacksonUtil	Internal Use Only.
  InternCache	Singleton class that adds a simple first-level cache in front of regular String.intern() functionality.
  JacksonFeatureSet<F extends JacksonFeature>	Container similar to EnumSet meant for storing sets of JacksonFeatures (usually Enums): main difference being that these sets are immutable.
  JsonGeneratorDelegate
  JsonParserDelegate	Helper class that implements delegation pattern for JsonParser, to allow for simple overridability of basic parsing functionality.
  JsonParserSequence	Helper class that can be used to sequence multiple physical JsonParsers to create a single logical sequence of tokens, as a single JsonParser.
  JsonRecyclerPools	Set of RecyclerPool implementations to be used by the default JSON-backed JsonFactory for recycling BufferRecycler containers.
  JsonRecyclerPools.BoundedPool	RecyclerPool implementation that uses a bounded queue (ArrayBlockingQueue for recycling instances.
  JsonRecyclerPools.ConcurrentDequePool	RecyclerPool implementation that uses ConcurrentLinkedDeque for recycling instances.
  JsonRecyclerPools.LockFreePool	RecyclerPool implementation that uses a lock free linked list for recycling instances.
  JsonRecyclerPools.NonRecyclingPool	Dummy RecyclerPool implementation that does not recycle anything but simply creates new instances when asked to acquire items.
  JsonRecyclerPools.ThreadLocalPool	ThreadLocal-based RecyclerPool implementation used for recycling BufferRecycler instances: see RecyclerPool.ThreadLocalPoolBase for full explanation of functioning.
  MinimalPrettyPrinter	PrettyPrinter implementation that adds no indentation, just implements everything necessary for value output to work as expected, and provide simpler extension points to allow for creating simple custom implementations that add specific decoration or overrides.
  ReadConstrainedTextBuffer
  RecyclerPool.BoundedPoolBase<P extends RecyclerPool.WithPool<P>>	RecyclerPool implementation that uses a bounded queue (ArrayBlockingQueue for recycling instances.
  RecyclerPool.ConcurrentDequePoolBase<P extends RecyclerPool.WithPool<P>>	RecyclerPool implementation that uses ConcurrentLinkedDeque for recycling instances.
  RecyclerPool.LockFreePoolBase<P extends RecyclerPool.WithPool<P>>	RecyclerPool implementation that uses a lock free linked list for recycling instances.
  RecyclerPool.LockFreePoolBase.Node<P>
  RecyclerPool.NonRecyclingPoolBase<P extends RecyclerPool.WithPool<P>>	RecyclerPool implementation that does not use any pool but simply creates new instances when necessary.
  RecyclerPool.StatefulImplBase<P extends RecyclerPool.WithPool<P>>	Intermediate base class for instances that are stateful and require special handling with respect to JDK serialization, to retain "global" reference distinct from non-shared ones.
  RecyclerPool.ThreadLocalPoolBase<P extends RecyclerPool.WithPool<P>>	Default RecyclerPool implementation that uses ThreadLocal for recycling instances.
  RequestPayload	Container object used to contain optional information on content being parsed, passed to JsonParseException in case of exception being thrown; this may be useful for caller to display information on failure.
  Separators	Value class used with some PrettyPrinter implements
  TextBuffer	TextBuffer is a class similar to StringBuffer, with following differences: TextBuffer uses segments character arrays, to avoid having to do additional array copies when array is not big enough.
  VersionUtil	Functionality for supporting exposing of component Versions.

• Enum Summary 

  Enum	Description
  Separators.Spacing	Define the spacing around elements like commas and colons.
