public abstract class StdDeserializer<T>
extends JsonDeserializer<T>

Base class for common deserializers. Contains shared base functionality for dealing with primitive values, such as (re)parsing from String.

static class	StdDeserializer.DoubleDeserializer

static class	StdDeserializer.IntegerDeserializer
static class	StdDeserializer.LongDeserializer
static class	StdDeserializer.NumberDeserializer For type Number.class, we can just rely on type mappings that plain JsonParser.getNumberValue() returns.
protected static class	StdDeserializer.PrimitiveOrWrapperDeserializer<T>
static class	StdDeserializer.ShortDeserializer
static class	StdDeserializer.SqlDateDeserializer Compared to plain old Date, SQL version is easier to deal with: mostly because it is more limited.
static class	StdDeserializer.StackTraceElementDeserializer
static class	StdDeserializer.StringDeserializer
static class	StdDeserializer.TokenBufferDeserializer We also want to directly support deserialization of TokenBuffer.

_valueClass

protected final Class<?> _valueClass

Type of values this deserializer handles: sometimes exact types, other time most specific supertype of types deserializer handles (which may be as generic as Object in some case)

Constructor Detail

StdDeserializer

protected StdDeserializer(Class<?> vc)

Method Detail

getValueClass

public Class<?> getValueClass()

Exact structured type deserializer handles, if known; null for non-structured (scalar) types.

Default implementation just returns null.

Helper method used to locate deserializers for properties the bean itself contains.

Parameters:

type - Type of property to deserialize

Throws:

JsonMappingException

handleUnknownProperty

protected void handleUnknownProperty(JsonParser jp,
                                     DeserializationContext ctxt,
                                     Object instanceOrClass,
                                     String propName)
                              throws IOException,
                                     JsonProcessingException

Method called to deal with a property that did not map to a known Bean property. Method can deal with the problem as it sees fit (ignore, throw exception); but if it does return, it has to skip the matching Json content parser has.

NOTE: method signature was changed in version 1.5; explicit JsonParser must be passed since it may be something other than what context has. Prior versions did not include the first parameter.

Parameters:

jp - Parser that points to value of the unknown property

ctxt - Context for deserialization; allows access to the parser, error reporting functionality

instanceOrClass - Instance that is being populated by this deserializer, or if not known, Class that would be instantiated. If null, will assume type is what getValueClass() returns.

propName - Name of the property that can not be mapped

Throws:

IOException

JsonProcessingException

reportUnknownProperty

protected void reportUnknownProperty(DeserializationContext ctxt,
                                     Object instanceOrClass,
                                     String fieldName)
                              throws IOException,
                                     JsonProcessingException

Throws:

IOException
