Class ObjectWriter.Prefetch

java.lang.Object

com.fasterxml.jackson.databind.ObjectWriter.Prefetch

All Implemented Interfaces:

Serializable

Enclosing class:

ObjectWriter

public static final class ObjectWriter.Prefetch
extends Object
implements Serializable

As a minor optimization, we will make an effort to pre-fetch a serializer, or at least relevant TypeSerializer, if given enough information.

Since:

2.5

Field Summary

Fields

Modifier and Type	Field and Description
static ObjectWriter.Prefetch	empty
JavaType	rootType Specified root serialization type to use; can be same as runtime type, but usually one of its super types
TypeSerializer	typeSerializer When dealing with polymorphic types, we can not pre-fetch serializer, but we can pre-fetch TypeSerializer.
JsonSerializer<Object>	valueSerializer We may pre-fetch serializer if rootType is known, and if so, reuse it afterwards.

Field Detail

empty

public static final ObjectWriter.Prefetch empty

rootType

public final JavaType rootType

Specified root serialization type to use; can be same as runtime type, but usually one of its super types

valueSerializer

public final JsonSerializer<Object> valueSerializer

We may pre-fetch serializer if rootType is known, and if so, reuse it afterwards. This allows avoiding further serializer lookups and increases performance a bit on cases where readers are reused.

typeSerializer

public final TypeSerializer typeSerializer

When dealing with polymorphic types, we can not pre-fetch serializer, but we can pre-fetch TypeSerializer.
