Class DeserializationContexts

java.lang.Object

tools.jackson.databind.cfg.DeserializationContexts

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

DeserializationContexts.DefaultImpl

public abstract class DeserializationContexts
extends Object
implements Serializable

Factory/builder class that replaces Jackson 2.x concept of "blueprint" instance of DeserializationContext. It will be constructed and configured during ObjectMapper building phase, and will be called once per readValue call to construct actual stateful DeserializationContext to use during serialization.

Note that since this object has to be serializable (to allow JDK serialization of mapper instances), DeserializationContext need not be serializable any more.

Since:

3.0

Method Details

forMapper

public DeserializationContexts forMapper(Object mapper,
 DeserializationConfig config,
 TokenStreamFactory tsf,
 DeserializerFactory deserializerFactory)

Mutant factory method called when instance is actually created for use by mapper (as opposed to coming into existence during building, module registration). Necessary usually to initialize non-configuration state, such as caching.

forMapper

protected abstract DeserializationContexts forMapper(Object mapper,
 TokenStreamFactory tsf,
 DeserializerFactory deserializerFactory,
 DeserializerCache cache)

createContext

public abstract DeserializationContextExt createContext(DeserializationConfig config,
 FormatSchema schema,
 InjectableValues injectables)

Factory method for constructing context object for individual writeValue call.

flushCachedDeserializers

public void flushCachedDeserializers()

Method that will drop all dynamically constructed deserializers (ones that are counted as result value for DeserializerCache.cachedDeserializersCount()).
