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

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.

Modifier and Type	Method and Description
void	checkUnresolvedObjectId() Method called to ensure that every object id encounter during processing are resolved.
DefaultDeserializationContext	copy() Method needed to ensure that ObjectMapper.copy() will work properly; specifically, that caches are cleared, but settings will otherwise remain identical; and that no sharing of state occurs.
