public abstract JsonDeserializer<java.lang.Object> unwrappingDeserializer(NameTransformer unwrapper)

Description copied from class: JsonDeserializer

Method that will return deserializer instance that is able to handle "unwrapped" value instances If no unwrapped instance can be constructed, will simply return this object as-is.

Default implementation just returns 'this' indicating that no unwrapped variant exists

Overrides:

Since:

2.1

resolve

public void resolve(DeserializationContext ctxt)
             throws JsonMappingException

Method called to finalize setup of this deserializer, after deserializer itself has been registered. This is needed to handle recursive and transitive dependencies.

Specified by:

resolve in interface ResolvableDeserializer

Parameters:

ctxt - Context to use for accessing configuration, resolving secondary deserializers

Throws:

JsonMappingException

findConvertingDeserializer

protected JsonDeserializer<java.lang.Object> findConvertingDeserializer(DeserializationContext ctxt,
                                                            SettableBeanProperty prop)
                                                                 throws JsonMappingException

Helper method that can be used to see if specified property is annotated to indicate use of a converter for property value (in case of container types, it is container type itself, not key or content type).

Throws:

JsonMappingException

Since:

2.2

createContextual

public JsonDeserializer<?> createContextual(DeserializationContext ctxt,
                                   BeanProperty property)
                                     throws JsonMappingException

Although most of post-processing is done in resolve(), we only get access to referring property's annotations here; and this is needed to support per-property ObjectIds. We will also consider Shape transformations (read from Array) at this point, since it may come from either Class definition or property.

Specified by:

createContextual in interface ContextualDeserializer

Parameters:

ctxt - Deserialization context to access configuration, additional deserializers that may be needed by this deserializer

property - 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 can not provide it and null is passed instead (in which case impls usually pass 'this' deserializer as is)

Returns:

Deserializer to use for deserializing values of specified property; may be this instance or a new instance.

Throws:

JsonMappingException

_resolveManagedReferenceProperty

protected SettableBeanProperty _resolveManagedReferenceProperty(DeserializationContext ctxt,
                                                    SettableBeanProperty prop)

Helper method called to see if given property is part of 'managed' property pair (managed + back reference), and if so, handle resolution details.

_resolveUnwrappedProperty

protected SettableBeanProperty _resolveUnwrappedProperty(DeserializationContext ctxt,
                                             SettableBeanProperty prop)

Helper method called to see if given property might be so-called unwrapped property: these require special handling.

_resolveInnerClassValuedProperty

protected SettableBeanProperty _resolveInnerClassValuedProperty(DeserializationContext ctxt,
                                                    SettableBeanProperty prop)

Helper method that will handle gruesome details of dealing with properties that have non-static inner class as value...

isCachable

public boolean isCachable()

Description copied from class: JsonDeserializer

Method called to see if deserializer instance is cachable and usable for other properties of same type (type for which instance was created).

Note that cached instances are still resolved on per-property basis, if instance implements ResolvableDeserializer: cached instance is just as the base. This means that in most cases it is safe to cache instances; however, it only makes sense to cache instances if instantiation is expensive, or if instances are heavy-weight.

Default implementation returns false, to indicate that no caching is done.

Overrides:

isCachable in class JsonDeserializer<java.lang.Object>

getObjectIdReader

public ObjectIdReader getObjectIdReader()

Overridden to return true for those instances that are handling value for which Object Identity handling is enabled (either via value type or referring property).

Overrides:

getObjectIdReader in class JsonDeserializer<java.lang.Object>

Returns:

ObjectIdReader used for resolving possible Object Identifier value, instead of full value serialization, if deserializer can do that; null if no Object Id is expected.

hasProperty

public boolean hasProperty(java.lang.String propertyName)

hasViews

public boolean hasViews()

getPropertyCount

public int getPropertyCount()

Accessor for checking number of deserialized properties.

getKnownPropertyNames

public java.util.Collection<java.lang.Object> getKnownPropertyNames()

Description copied from class: JsonDeserializer

Method that will either return null to indicate that type being deserializers has no concept of properties; or a collection of identifiers for which toString will give external property name. This is only to be used for error reporting and diagnostics purposes (most commonly, to accompany "unknown property" exception).

Overrides:

getKnownPropertyNames in class JsonDeserializer<java.lang.Object>

getBeanClass

public final java.lang.Class<?> getBeanClass()

getValueType

public JavaType getValueType()

Description copied from class: StdDeserializer

Exact structured type deserializer handles, if known.

Default implementation just returns null.

Overrides:

getValueType in class StdDeserializer<java.lang.Object>

Accessor for iterating over properties this deserializer uses; with the exception that properties passed via Creator methods (specifically, "property-based constructor") are not included, but can be accessed separate by calling creatorProperties()

Accessor for finding properties that represents values to pass through property-based creator method (constructor or factory method)

Since:

Method needed by BeanDeserializerFactory to properly link managed- and back-reference pairs.

                   SettableBeanProperty replacement)

Parameters:

original - Property to replace

replacement - Property to replace it with

                                     com.fasterxml.jackson.core.JsonProcessingException

Method called when a JSON property is encountered that has not matching setter, any-setter or field, and thus can not be assigned.

Overrides:

handleUnknownProperty in class StdDeserializer<java.lang.Object>

Parameters:

jp - Parser that points to value of the unknown property

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

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

propName - Name of the property that can not be mapped

Throws:

java.io.IOException

com.fasterxml.jackson.core.JsonProcessingException

Method called in cases where we may have polymorphic deserialization case: that is, type of Creator-constructed bean is not the type of deserializer itself. It should be a sub-class or implementation class; either way, we may have more specific deserializer to use for handling it.

Parameters:

jp - (optional) If not null, parser that has more properties to handle (in addition to buffered properties); if null, all properties are passed in buffer

Throws:

java.io.IOException

com.fasterxml.jackson.core.JsonProcessingException

wrapAndThrow

public void wrapAndThrow(java.lang.Throwable t,

                DeserializationContext ctxt)
                  throws java.io.IOException

Method that will modify caught exception (passed in as argument) as necessary to include reference information, and to ensure it is a subtype of IOException, or an unchecked exception.

Rules for wrapping and unwrapping are bit complicated; essentially:

• Errors are to be passed as is (if uncovered via unwrapping)
• "Plain" IOExceptions (ones that are not of type JsonMappingException are to be passed as is

Throws:

java.io.IOException
