Package com.fasterxml.jackson.databind.deser

Class DefaultDeserializationContext

java.lang.Object

com.fasterxml.jackson.databind.DatabindContext

com.fasterxml.jackson.databind.DeserializationContext

com.fasterxml.jackson.databind.deser.DefaultDeserializationContext

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

DefaultDeserializationContext.Impl, XmlDeserializationContext

public abstract class DefaultDeserializationContext
extends DeserializationContext
implements Serializable

Complete DeserializationContext implementation that adds extended API for ObjectMapper (and ObjectReader) to call, as well as implements certain parts that base class has left abstract. The remaining abstract methods (createInstance(com.fasterxml.jackson.databind.DeserializationConfig, com.fasterxml.jackson.core.JsonParser, com.fasterxml.jackson.databind.InjectableValues), with(com.fasterxml.jackson.databind.deser.DeserializerFactory)) are left so that custom implementations will properly implement them to return intended subtype.
