All Implemented Interfaces:

com.fasterxml.jackson.core.Versioned

public class ObjectReader
extends com.fasterxml.jackson.core.ObjectCodec
implements com.fasterxml.jackson.core.Versioned

Builder object that can be used for per-serialization configuration of deserialization parameters, such as root type to use or object to update (instead of constructing new instance).

Uses "fluent" (aka builder) pattern so that instances are immutable (and thus fully thread-safe with no external synchronization); new instances are constructed for different configurations. Instances are initially constructed by ObjectMapper and can be reused, shared, cached; both because of thread-safety and because instances are relatively light-weight.
