Class IOContext

java.lang.Object

com.fasterxml.jackson.core.io.IOContext

public class IOContext
extends java.lang.Object

To limit number of configuration and state objects to pass, all contextual objects that need to be passed by the factory to readers and writers are combined under this object. One instance is created for each reader and writer.

NOTE: non-final since 2.4, to allow sub-classing.
