Package com.fasterxml.jackson.databind

Class ObjectMapper.DefaultTypeResolverBuilder

java.lang.Object

com.fasterxml.jackson.databind.jsontype.impl.StdTypeResolverBuilder

com.fasterxml.jackson.databind.ObjectMapper.DefaultTypeResolverBuilder

All Implemented Interfaces:

TypeResolverBuilder<StdTypeResolverBuilder>, Serializable

Direct Known Subclasses:

DefaultingXmlTypeResolverBuilder

Enclosing class:

ObjectMapper

public static class ObjectMapper.DefaultTypeResolverBuilder
extends StdTypeResolverBuilder
implements Serializable

Customized TypeResolverBuilder that provides type resolver builders used with so-called "default typing" (see ObjectMapper.activateDefaultTyping(PolymorphicTypeValidator) for details).

Type resolver construction is based on configuration: implementation takes care of only providing builders in cases where type information should be applied. This is important since build calls may be sent for any and all types, and type information should NOT be applied to all of them.

construct

public static ObjectMapper.DefaultTypeResolverBuilder construct(ObjectMapper.DefaultTyping t,
 PolymorphicTypeValidator ptv)

Since:

2.10

withDefaultImpl

public ObjectMapper.DefaultTypeResolverBuilder withDefaultImpl(Class<?> defaultImpl)

Description copied from interface: TypeResolverBuilder

"Mutant factory" method for creating a new instance with different default implementation.

Specified by:

withDefaultImpl in interface TypeResolverBuilder<StdTypeResolverBuilder>

Overrides:

withDefaultImpl in class StdTypeResolverBuilder

Returns:

Either this instance (if nothing changed) or a new instance with different default implementation

subTypeValidator

public PolymorphicTypeValidator subTypeValidator(MapperConfig<?> config)

Description copied from class: StdTypeResolverBuilder

Overridable helper method for determining actual validator to use when constructing type serializers and type deserializers.

Default implementation simply uses one configured and accessible using MapperConfig.getPolymorphicTypeValidator().

Overrides:

subTypeValidator in class StdTypeResolverBuilder

buildTypeDeserializer

public TypeDeserializer buildTypeDeserializer(DeserializationConfig config,
 JavaType baseType,
 Collection<NamedType> subtypes)

Description copied from interface: TypeResolverBuilder

Method for building type deserializer based on current configuration of this builder.

Specified by:

buildTypeDeserializer in interface TypeResolverBuilder<StdTypeResolverBuilder>

Overrides:

buildTypeDeserializer in class StdTypeResolverBuilder

Parameters:

baseType - Base type that constructed resolver will handle; super type of all types it will be used for.

subtypes - Known subtypes of the base type.

buildTypeSerializer

public TypeSerializer buildTypeSerializer(SerializationConfig config,
 JavaType baseType,
 Collection<NamedType> subtypes)

Description copied from interface: TypeResolverBuilder

Method for building type serializer based on current configuration of this builder.

Specified by:

buildTypeSerializer in interface TypeResolverBuilder<StdTypeResolverBuilder>

Overrides:

buildTypeSerializer in class StdTypeResolverBuilder

Parameters:

baseType - Base type that constructed resolver will handle; super type of all types it will be used for.

useForType

public boolean useForType(JavaType t)

Method called to check if the default type handler should be used for given type. Note: "natural types" (String, Boolean, Integer, Double) will never use typing; that is both due to them being concrete and final, and since actual serializers and deserializers will also ignore any attempts to enforce typing.
