Package com.fasterxml.jackson.core.util

Utility classes used by Jackson Core functionality.

Interface Summary

Interface	Description
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.

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	Helper entity used to control access to simple buffer recyling scheme used for some encoding, decoding tasks.
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
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.
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.
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.
