Packages that use com.fasterxml.jackson.core.util

Package	Description
com.fasterxml.jackson.core	Main public API classes of the core streaming JSON processor: most importantly JsonFactory used for constructing JSON parser (JsonParser) and generator (JsonGenerator) instances.
com.fasterxml.jackson.core.base	Base classes used by concrete Parser and Generator implementations; contain functionality that is not specific to JSON or input abstraction (byte vs char).
com.fasterxml.jackson.core.filter
com.fasterxml.jackson.core.io
com.fasterxml.jackson.core.util	Utility classes used by Jackson Core functionality.

Classes in com.fasterxml.jackson.core.util used by com.fasterxml.jackson.core

Class and Description
BufferRecycler This is a small utility class, whose main functionality is to allow simple reuse of raw byte/char buffers.
ByteArrayBuilder Helper class that is similar to ByteArrayOutputStream in usage, but more geared to Jackson use cases internally.

Class and Description
ByteArrayBuilder Helper class that is similar to ByteArrayOutputStream in usage, but more geared to Jackson use cases internally.
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.

Class and Description
JsonGeneratorDelegate
JsonParserDelegate Helper class that implements delegation pattern for JsonParser, to allow for simple overridability of basic parsing functionality.

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.Indenter Interface that defines objects that can produce indentation used to separate object entries and array values.
DefaultPrettyPrinter.Lf2SpacesIndenter Deprecated. Since 2.5 use DefaultIndenter instead
DefaultPrettyPrinter.NopIndenter Dummy implementation that adds no indentation whatsoever
Instantiatable 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.
InternCache Singleton class that adds a simple first-level cache in front of regular String.intern() functionality.
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.
