Package com.fasterxml.jackson.databind.jsontype.impl

Class TypeNameIdResolver

java.lang.Object

com.fasterxml.jackson.databind.jsontype.impl.TypeIdResolverBase

com.fasterxml.jackson.databind.jsontype.impl.TypeNameIdResolver

All Implemented Interfaces:

TypeIdResolver, Serializable

public class TypeNameIdResolver
extends TypeIdResolverBase
implements Serializable

TypeIdResolver implementation that converts using explicitly (annotation-) specified type names and maps to implementation classes; or, in absence of annotated type name, defaults to fully-qualified Class names (obtained with Class.getName()

Method Summary

Modifier and Type	Method	Description
static TypeNameIdResolver	construct(MapperConfig<?> config, JavaType baseType, Collection<NamedType> subtypes, boolean forSer, boolean forDeser)
String	getDescForKnownTypeIds()	Helper method used to get a simple description of all known type ids, for use in error messages.
JsonTypeInfo.Id	getMechanism()	Accessor for mechanism that this resolver uses for determining type id from type.
String	idFromValue(Object value)	Method called to serialize type of the type of given value as a String to include in serialized JSON content.
String	idFromValueAndType(Object value, Class<?> type)	Alternative method used for determining type from combination of value and type, using suggested type (that serializer provides) and possibly value of that type.
String	toString()
JavaType	typeFromId(DatabindContext context, String id)	Method called to resolve type from given type identifier.

Method Details

construct

public static TypeNameIdResolver construct(MapperConfig<?> config,
 JavaType baseType,
 Collection<NamedType> subtypes,
 boolean forSer,
 boolean forDeser)

getMechanism

public JsonTypeInfo.Id getMechanism()

Description copied from interface: TypeIdResolver

Accessor for mechanism that this resolver uses for determining type id from type. Mostly informational; not required to be called or used.

Specified by:

getMechanism in interface TypeIdResolver

idFromValue

public String idFromValue(Object value)

Description copied from interface: TypeIdResolver

Method called to serialize type of the type of given value as a String to include in serialized JSON content.

Specified by:

idFromValue in interface TypeIdResolver

idFromValueAndType

public String idFromValueAndType(Object value,
 Class<?> type)

Description copied from interface: TypeIdResolver

Alternative method used for determining type from combination of value and type, using suggested type (that serializer provides) and possibly value of that type. Most common implementation will use suggested type as is.

Specified by:

idFromValueAndType in interface TypeIdResolver

typeFromId

public JavaType typeFromId(DatabindContext context,
 String id)

Description copied from interface: TypeIdResolver

Method called to resolve type from given type identifier.

Specified by:

typeFromId in interface TypeIdResolver

Overrides:

typeFromId in class TypeIdResolverBase

getDescForKnownTypeIds

public String getDescForKnownTypeIds()

Description copied from class: TypeIdResolverBase

Helper method used to get a simple description of all known type ids, for use in error messages.

Specified by:

getDescForKnownTypeIds in interface TypeIdResolver

Overrides:

getDescForKnownTypeIds in class TypeIdResolverBase

toString

public String toString()

Overrides:

toString in class Object
