com.fasterxml.jackson.databind.jsontype.PolymorphicTypeValidator

Packages that use PolymorphicTypeValidator

Package	Description
com.fasterxml.jackson.databind	Basic data binding (mapping) functionality that allows for reading JSON content into Java Objects (POJOs) and JSON Trees (JsonNode), as well as writing Java Objects and trees as JSON.
com.fasterxml.jackson.databind.cfg	Package that contains most of configuration-related classes; exception being couple of most-commonly used configuration things (like Feature enumerations) that are at the main level (com.fasterxml.jackson.databind).

Uses of PolymorphicTypeValidator in com.fasterxml.jackson.databind

Fields in com.fasterxml.jackson.databind declared as PolymorphicTypeValidator

Modifier and Type	Field	Description
protected final PolymorphicTypeValidator	ObjectMapper.DefaultTypeResolverBuilder._subtypeValidator	PolymorphicTypeValidator top use for validating that the subtypes resolved are valid for use (usually to protect against possible security issues)

Methods in com.fasterxml.jackson.databind that return PolymorphicTypeValidator

Modifier and Type	Method	Description
PolymorphicTypeValidator	ObjectMapper.getPolymorphicTypeValidator()	Accessor for configured PolymorphicTypeValidator used for validating polymorphic subtypes used with explicit polymorphic types (annotation-based), but NOT one with "default typing" (see ObjectMapper.activateDefaultTyping(PolymorphicTypeValidator) for details).
PolymorphicTypeValidator	ObjectMapper.DefaultTypeResolverBuilder.subTypeValidator(MapperConfig<?> config)

Methods in com.fasterxml.jackson.databind with parameters of type PolymorphicTypeValidator

Modifier and Type	Method	Description
protected TypeResolverBuilder<?>	ObjectMapper._constructDefaultTypeResolverBuilder(ObjectMapper.DefaultTyping applicability, PolymorphicTypeValidator ptv)	Overridable factory method, separate to allow format-specific mappers (and specifically XML-backed one, currently) to offer custom TypeResolverBuilder subtypes.
protected <T> T	DatabindContext._throwSubtypeClassNotAllowed(JavaType baseType, String subType, PolymorphicTypeValidator ptv)
protected <T> T	DatabindContext._throwSubtypeNameNotAllowed(JavaType baseType, String subType, PolymorphicTypeValidator ptv)
ObjectMapper	ObjectMapper.activateDefaultTyping(PolymorphicTypeValidator ptv)	Convenience method that is equivalent to calling
ObjectMapper	ObjectMapper.activateDefaultTyping(PolymorphicTypeValidator ptv, ObjectMapper.DefaultTyping applicability)	Convenience method that is equivalent to calling
ObjectMapper	ObjectMapper.activateDefaultTyping(PolymorphicTypeValidator ptv, ObjectMapper.DefaultTyping applicability, com.fasterxml.jackson.annotation.JsonTypeInfo.As includeAs)	Method for enabling automatic inclusion of type information ("Default Typing"), needed for proper deserialization of polymorphic types (unless types have been annotated with JsonTypeInfo).
ObjectMapper	ObjectMapper.activateDefaultTypingAsProperty(PolymorphicTypeValidator ptv, ObjectMapper.DefaultTyping applicability, String propertyName)	Method for enabling automatic inclusion of type information ("Default Typing") -- needed for proper deserialization of polymorphic types (unless types have been annotated with JsonTypeInfo) -- using "As.PROPERTY" inclusion mechanism and specified property name to use for inclusion (default being "@class" since default type information always uses class name as type identifier)
static ObjectMapper.DefaultTypeResolverBuilder	ObjectMapper.DefaultTypeResolverBuilder.construct(ObjectMapper.DefaultTyping t, PolymorphicTypeValidator ptv)
JavaType	DatabindContext.resolveAndValidateSubType(JavaType baseType, String subClass, PolymorphicTypeValidator ptv)	Lookup method similar to DatabindContext.resolveSubType(JavaType, String) but one that also validates that resulting subtype is valid according to given PolymorphicTypeValidator.
ObjectMapper	ObjectMapper.setPolymorphicTypeValidator(PolymorphicTypeValidator ptv)	Method for specifying PolymorphicTypeValidator to use for validating polymorphic subtypes used with explicit polymorphic types (annotation-based), but NOT one with "default typing" (see ObjectMapper.activateDefaultTyping(PolymorphicTypeValidator) for details).

Uses of PolymorphicTypeValidator in com.fasterxml.jackson.databind.cfg

Fields in com.fasterxml.jackson.databind.cfg declared as PolymorphicTypeValidator

Modifier and Type	Field	Description
protected final PolymorphicTypeValidator	BaseSettings._typeValidator	Validator that is used to limit allowed polymorphic subtypes, mostly for security reasons when dealing with untrusted content.

Modifier and Type	Method	Description
PolymorphicTypeValidator	BaseSettings.getPolymorphicTypeValidator()
PolymorphicTypeValidator	MapperConfig.getPolymorphicTypeValidator()	Simple accessor for default PolymorphicTypeValidator to use for legacy Default Typing methods (ObjectMapper.enableDefaultTyping()) and annotation based enabling.

B	MapperBuilder.activateDefaultTyping(PolymorphicTypeValidator subtypeValidator, ObjectMapper.DefaultTyping applicability, com.fasterxml.jackson.annotation.JsonTypeInfo.As includeAs)	Method for enabling automatic inclusion of type information, needed for proper deserialization of polymorphic types (unless types have been annotated with JsonTypeInfo).
B	MapperBuilder.activateDefaultTypingAsProperty(PolymorphicTypeValidator subtypeValidator, ObjectMapper.DefaultTyping applicability, String propertyName)	Method for enabling automatic inclusion of type information -- needed for proper deserialization of polymorphic types (unless types have been annotated with JsonTypeInfo) -- using "As.PROPERTY" inclusion mechanism and specified property name to use for inclusion (default being "@class" since default type information always uses class name as type identifier)
B	MapperBuilder.polymorphicTypeValidator(PolymorphicTypeValidator ptv)	Method for assigning PolymorphicTypeValidator to use for validating subtypes when using Class name - based polymorphic deserialization using annotations (validator used with "Default Typing" is specified by passing in MapperBuilder.activateDefaultTyping(PolymorphicTypeValidator) instead).
