com.fasterxml.jackson.annotation.JsonTypeInfo, tools.jackson.core.JacksonException, .JsonParser, tools.jackson.core.exc.StreamReadException, tools.jackson.databind.*, tools.jackson.databind.jsontype.TypeDeserializer, .TypeIdResolver, tools.jackson.databind.jsontype.impl.TypeDeserializerBase, tools.jackson.dataformat.ion.IonParser
This is a tools.jackson.databind.jsontype.TypeDeserializer that reads typing metadata from Ion type annotations. Annotations found are processed by the configured TypeIdResolver to provide a concrete Java class, which is in turn used to find the appropriate ValueDeserializer, and execute it.

If multiple annotations are found, the first annotation to resolve to a non-null JavaType using the configured TypeIdResolver is used. Ion provides type annotations in alphabetic order.

Method Summary

Modifier and TypeMethod and Description
private Object
_deserialize(JsonParser p, DeserializationContext ctxt)

public Object
deserializeTypedFromAny(JsonParser p, DeserializationContext ctxt)

Implements abstract tools.jackson.databind.jsontype.TypeDeserializer.deserializeTypedFromAny.

Method called to let this type deserializer handle deserialization of "typed" object, when value itself may have been serialized using any kind of JSON value (Array, Object, scalar).

public Object
deserializeTypedFromArray(JsonParser p, DeserializationContext ctxt)

Implements abstract tools.jackson.databind.jsontype.TypeDeserializer.deserializeTypedFromArray.

Method called to let this type deserializer handle deserialization of "typed" object, when value itself is serialized as JSON Array (regardless of Java type).

public Object
deserializeTypedFromObject(JsonParser p, DeserializationContext ctxt)

Implements abstract tools.jackson.databind.jsontype.TypeDeserializer.deserializeTypedFromObject.

Method called to let this type deserializer handle deserialization of "typed" object, when value itself is serialized as JSON Object (regardless of Java type).

public Object
deserializeTypedFromScalar(JsonParser p, DeserializationContext ctxt)

Implements abstract tools.jackson.databind.jsontype.TypeDeserializer.deserializeTypedFromScalar.

Method called to let this type deserializer handle deserialization of "typed" object, when value itself is serialized as a scalar JSON value (something other than Array or Object), regardless of Java type.

public TypeDeserializer
forProperty(BeanProperty prop)

Implements abstract tools.jackson.databind.jsontype.impl.TypeDeserializerBase.forProperty.

Method called to create contextual version, to be used for values of given property.

public JsonTypeInfo.As

Returns:

null
getTypeInclusion()

Implements abstract tools.jackson.databind.jsontype.impl.TypeDeserializerBase.getTypeInclusion.

Used for informational purposes and some serialization-implementation-specific logics (which do not concern us).

public Object deserializeTypedFromAny(JsonParser p, DeserializationContext ctxt)

Implements abstract tools.jackson.databind.jsontype.TypeDeserializer.deserializeTypedFromAny.

Doc from tools.jackson.databind.jsontype.TypeDeserializer.deserializeTypedFromAny.

Method called to let this type deserializer handle deserialization of "typed" object, when value itself may have been serialized using any kind of JSON value (Array, Object, scalar). Should only be called if JSON serialization is polymorphic (not Java type); for example when using JSON node representation, or "untyped" Java object (which may be Map, Collection, wrapper/primitive etc).

public Object deserializeTypedFromArray(JsonParser p, DeserializationContext ctxt)

Implements abstract tools.jackson.databind.jsontype.TypeDeserializer.deserializeTypedFromArray.

Doc from tools.jackson.databind.jsontype.TypeDeserializer.deserializeTypedFromArray.

Method called to let this type deserializer handle deserialization of "typed" object, when value itself is serialized as JSON Array (regardless of Java type). Method needs to figure out intended polymorphic type, locate ValueDeserializer to use, and call it with JSON data to deserializer (which does not contain type information).

public TypeDeserializer forProperty(BeanProperty prop)

Implements abstract tools.jackson.databind.jsontype.impl.TypeDeserializerBase.forProperty.

Doc from tools.jackson.databind.jsontype.TypeDeserializer.forProperty.

Method called to create contextual version, to be used for values of given property. This may be the type itself (as is the case for bean properties), or values contained (for java.util.Collection or java.util.Map valued properties).

public JsonTypeInfo.As getTypeInclusion()

Implements abstract tools.jackson.databind.jsontype.impl.TypeDeserializerBase.getTypeInclusion.

Used for informational purposes and some serialization-implementation-specific logics (which do not concern us). We have to return an enum which we cannot extend, and none of them accurately reflect what we do.

Returns:JsonTypeInfo.As
