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.

Constructor Detail

DefaultDeserializationContext

protected DefaultDeserializationContext(DeserializerFactory df,
                                        DeserializerCache cache)

Constructor that will pass specified deserializer factory and cache: cache may be null (in which case default implementation will be used), factory cannot be null

DefaultDeserializationContext

protected DefaultDeserializationContext(DefaultDeserializationContext src,
                                        DeserializationConfig config,
                                        JsonParser p,
                                        InjectableValues values)

DefaultDeserializationContext

protected DefaultDeserializationContext(DefaultDeserializationContext src,
                                        DeserializationConfig config)

DefaultDeserializationContext

protected DefaultDeserializationContext(DefaultDeserializationContext src,
                                        DeserializerFactory factory)

DefaultDeserializationContext

protected DefaultDeserializationContext(DefaultDeserializationContext src)

Since:

2.4.4

Method Detail

copy

public 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.

Since:

2.4.4

findObjectId

public ReadableObjectId findObjectId(Object id,
                                     ObjectIdGenerator<?> gen,
                                     ObjectIdResolver resolverType)

Description copied from class: DeserializationContext

Method called to find and return entry corresponding to given Object Id: will add an entry if necessary, and never returns null

Specified by:

findObjectId in class DeserializationContext

createReadableObjectId

protected ReadableObjectId createReadableObjectId(ObjectIdGenerator.IdKey key)

Overridable factory method to create a new instance of ReadableObjectId or its subclass. It is meant to be overridden when custom ReadableObjectId is needed for tryToResolveUnresolvedObjectId(com.fasterxml.jackson.databind.deser.impl.ReadableObjectId). Default implementation simply constructs default ReadableObjectId with given key.

Parameters:

key - The key to associate with the new ReadableObjectId

Returns:

New ReadableObjectId instance

Since:

2.7

checkUnresolvedObjectId

public void checkUnresolvedObjectId()
                             throws UnresolvedForwardReference

Description copied from class: DeserializationContext

Method called to ensure that every object id encounter during processing are resolved.

Specified by:

checkUnresolvedObjectId in class DeserializationContext

Throws:

UnresolvedForwardReference

tryToResolveUnresolvedObjectId

protected boolean tryToResolveUnresolvedObjectId(ReadableObjectId roid)

Overridable helper method called to try to resolve otherwise unresolvable ReadableObjectId; and if this succeeds, return true to indicate problem has been resolved in some way, so that caller can avoid reporting it as an error.

Default implementation simply calls ReadableObjectId.tryToResolveUnresolved(com.fasterxml.jackson.databind.DeserializationContext) and returns whatever it returns.

Since:

2.6
