Method Summary

Modifier and TypeMethod and Description
public XmlDeserializationContext
copy()

Overrides com.fasterxml.jackson.databind.deser.DefaultDeserializationContext.copy.

Method needed to ensure that ObjectMapper#copy will work properly; specifically, that caches are cleared, but settings will otherwise remain identical; and that no sharing of state occurs.

public DefaultDeserializationContext
createDummyInstance(DeserializationConfig config)

Implements abstract com.fasterxml.jackson.databind.deser.DefaultDeserializationContext.createDummyInstance.

public DefaultDeserializationContext
createInstance(DeserializationConfig config, JsonParser p, InjectableValues values)

Implements abstract com.fasterxml.jackson.databind.deser.DefaultDeserializationContext.createInstance.

Method called to create actual usable per-deserialization context instance.

public String
extractScalarFromObject(JsonParser
Actual parser to read content from
p, JsonDeserializer<?>
Deserializer that needs extracted String value
deser, Class<?>
Immediate type of scalar to extract; usually type deserializer handles but not always (for example, deserializer for int[] would pass scalar type of int)
scalarType)

Overrides com.fasterxml.jackson.databind.DeserializationContext.extractScalarFromObject.

Method to call in case incoming shape is Object Value (and parser thereby points to com.fasterxml.jackson.core.JsonToken#START_OBJECT token), but a Scalar value (potentially coercible from String value) is expected.

public Object
readRootValue(JsonParser p, JavaType valueType, JsonDeserializer<Object> deser, Object valueToUpdate)

Overrides com.fasterxml.jackson.databind.deser.DefaultDeserializationContext.readRootValue.

public DefaultDeserializationContext
with(DeserializerFactory factory)

Implements abstract com.fasterxml.jackson.databind.deser.DefaultDeserializationContext.with.

Fluent factory method used for constructing a blueprint instance with different factory

public DefaultDeserializationContext
withCaches(CacheProvider cp)

Implements abstract com.fasterxml.jackson.databind.deser.DefaultDeserializationContext.withCaches.

Fluent factory method used for constructing a new instance with cache instances provided by CacheProvider.

Overrides com.fasterxml.jackson.databind.DeserializationContext.extractScalarFromObject.

Doc from com.fasterxml.jackson.databind.DeserializationContext.extractScalarFromObject.

Method to call in case incoming shape is Object Value (and parser thereby points to com.fasterxml.jackson.core.JsonToken#START_OBJECT token), but a Scalar value (potentially coercible from String value) is expected. This would typically be used to deserializer a Number, Boolean value or some other "simple" unstructured value type.

Parameters
p:JsonParser

Actual parser to read content from

deser:JsonDeserializer<?>

Deserializer that needs extracted String value

scalarType:Class<?>

Immediate type of scalar to extract; usually type deserializer handles but not always (for example, deserializer for int[] would pass scalar type of int)

Returns:String

String value found; not null (exception should be thrown if no suitable value found)

Annotations
@Override
Exceptions
IOException:
If there are problems either reading content (underlying parser problem) or finding expected scalar value
