## Uses of Class
com.fasterxml.jackson.core.io.IOContext

- Packages that use IOContext
  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.io |
  com.fasterxml.jackson.core.json | JSON-specific parser and generator implementation classes that Jackson defines and uses.
  com.fasterxml.jackson.core.json.async | Non-blocking ("async") JSON parser implementation.
