jackson-databind 2.16.0 · com.fasterxml.jackson.databind.deser.std.UntypedObjectDeserializer

Deserializer implementation that is used if it is necessary to bind content of "unknown" type; something declared as basic java.lang.Object (either explicitly, or due to type erasure). If so, "natural" mapping is used to convert JSON values to their natural Java object matches: JSON arrays to Java java.util.Lists (or, if configured, Object[]), JSON objects to java.util.Maps, numbers to java.lang.Numbers, booleans to java.lang.Booleans and strings to java.lang.String (and nulls to nulls).

Modifier and Type	Class and Description
public static class	UntypedObjectDeserializer.Vanilla Deprecated Streamlined version of `UntypedObjectDeserializer` that has fewer checks and is only used when no custom deserializer overrides are applied.

Modifier and Type	Field and Description
protected JsonDeserializer<Object>	_listDeserializer
protected JavaType	_listType If `java.util.List` has been mapped to non-default implementation, we'll store type here
protected JsonDeserializer<Object>	_mapDeserializer
protected JavaType	_mapType If `java.util.Map` has been mapped to non-default implementation, we'll store type here
protected final boolean	_nonMerging
protected JsonDeserializer<Object>	_numberDeserializer
protected JsonDeserializer<Object>	_stringDeserializer
protected static final Object[]	NO_OBJECTS
private static final long	serialVersionUID Hides com.fasterxml.jackson.databind.deser.std.StdDeserializer.serialVersionUID.

Access	Constructor and Description
public	UntypedObjectDeserializer() Deprecated Since 2.6 use variant takes type arguments

Method Summary

Modifier and Type	Method and Description
protected JsonDeserializer<Object>	_clearIfStdImpl(JsonDeserializer<Object> deser)
protected JsonDeserializer<Object>	_findCustomDeser(DeserializationContext ctxt, JavaType type)
protected Object	_mapObjectWithDups(JsonParser p, DeserializationContext ctxt, final Map<String, Object> result, String key, Object oldValue, Object newValue, String nextKey)
private void	_squashDups(final Map<String, Object> result, String key, Object oldValue, Object newValue)
public JsonDeserializer<?>	createContextual(DeserializationContext Deserialization context to access configuration, additional deserializers that may be needed by this deserializer ctxt, BeanProperty Method, field or constructor parameter that represents the property (and is used to assign deserialized value). Should be available; but there may be cases where caller cannot provide it and null is passed instead (in which case impls usually pass 'this' deserializer as is) property) Implements com.fasterxml.jackson.databind.deser.ContextualDeserializer.createContextual. We only use contextualization for optimizing the case where no customization occurred; if so, can slip in a more streamlined version.
public Object	deserialize(JsonParser Parsed used for reading JSON content p, DeserializationContext Context that can be used to access information about this deserialization activity. ctxt) Implements abstract com.fasterxml.jackson.databind.JsonDeserializer.deserialize. Method that can be called to ask implementation to deserialize JSON content into the value type this serializer handles.
public Object	deserialize(JsonParser p, DeserializationContext ctxt, Object intoValue) Overrides com.fasterxml.jackson.databind.JsonDeserializer.deserialize. Alternate deserialization method (compared to the most commonly used, `deserialize(JsonParser, DeserializationContext)`), which takes in initialized value instance, to be configured and/or populated by deserializer.
public Object	deserializeWithType(JsonParser p, DeserializationContext ctxt, TypeDeserializer Deserializer to use for handling type information typeDeserializer) Overrides com.fasterxml.jackson.databind.deser.std.StdDeserializer.deserializeWithType. Base implementation that does not assume specific type inclusion mechanism.
public boolean	isCachable() Overrides com.fasterxml.jackson.databind.JsonDeserializer.isCachable. Method called to see if deserializer instance is cachable and usable for other properties of same type (type for which instance was created).
public LogicalType	logicalType() Overrides com.fasterxml.jackson.databind.JsonDeserializer.logicalType. Method for accessing logical type of values this deserializer produces.
protected Object	mapArray(JsonParser p, DeserializationContext ctxt) Method called to map a JSON Array into a Java value.
protected Object	mapArray(JsonParser p, DeserializationContext ctxt, Collection<Object> result)
protected Object[]	mapArrayToArray(JsonParser p, DeserializationContext ctxt) Method called to map a JSON Array into a Java Object array (Object[]).
protected Object	mapObject(JsonParser p, DeserializationContext ctxt) Method called to map a JSON Object into a Java value.
protected Object	mapObject(JsonParser p, DeserializationContext ctxt, Map<Object, Object> m)
public void	resolve(DeserializationContext Context to use for accessing configuration, resolving secondary deserializers ctxt) Implements com.fasterxml.jackson.databind.deser.ResolvableDeserializer.resolve. We need to implement this method to properly find things to delegate to: it cannot be done earlier since delegated deserializers almost certainly require access to this instance (at least "List" and "Map" ones)
public Boolean	supportsUpdate(DeserializationConfig config) Overrides com.fasterxml.jackson.databind.JsonDeserializer.supportsUpdate. Introspection method that may be called to see whether deserializer supports update of an existing value (aka "merging") or not.
