Constructor Detail

• AbstractDeserializer

                      BeanDescription beanDesc,

Method Detail

• constructForNonPOJO

  public static AbstractDeserializer constructForNonPOJO(BeanDescription beanDesc)

  Factory method used when constructing instances for non-POJO types, like Maps.

  Since:

  2.3

• handledType

  public Class<?> handledType()

  Description copied from class: JsonDeserializer
  Method for accessing type of values this deserializer produces. Note that this information is not guaranteed to be exact -- it may be a more generic (super-type) -- but it should not be incorrect (return a non-related type).

  Default implementation will return null, which means almost same same as returning Object.class would; that is, that nothing is known about handled type.

  Overrides:

  handledType in class JsonDeserializer<Object>

• 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<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<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.

• findBackReference

  public SettableBeanProperty findBackReference(String logicalName)

  Method called by BeanDeserializer to resolve back reference part of managed references.

  Overrides:

  findBackReference in class JsonDeserializer<Object>

• deserializeWithType

  public Object deserializeWithType(com.fasterxml.jackson.core.JsonParser jp,
                           DeserializationContext ctxt,
                           TypeDeserializer typeDeserializer)
                             throws IOException,
                                    com.fasterxml.jackson.core.JsonProcessingException

  Description copied from class: JsonDeserializer
  Deserialization called when type being deserialized is defined to contain additional type identifier, to allow for correctly instantiating correct subtype. This can be due to annotation on type (or its supertype), or due to global settings without annotations.

  Default implementation may work for some types, but ideally subclasses should not rely on current default implementation. Implementation is mostly provided to avoid compilation errors with older code.

  Overrides:

  deserializeWithType in class JsonDeserializer<Object>

  typeDeserializer - Deserializer to use for handling type information

  Throws:

  IOException

  com.fasterxml.jackson.core.JsonProcessingException

• deserialize

  public Object deserialize(com.fasterxml.jackson.core.JsonParser jp,
                   DeserializationContext ctxt)
                     throws IOException,
                            com.fasterxml.jackson.core.JsonProcessingException

  Description copied from class: JsonDeserializer
  Method that can be called to ask implementation to deserialize JSON content into the value type this serializer handles. Returned instance is to be constructed by method itself.

  Pre-condition for this method is that the parser points to the first event that is part of value to deserializer (and which is never JSON 'null' literal, more on this below): for simple types it may be the only value; and for structured types the Object start marker. Post-condition is that the parser will point to the last event that is part of deserialized value (or in case deserialization fails, event that was not recognized or usable, which may be the same event as the one it pointed to upon call).

  Note that this method is never called for JSON null literal, and thus deserializers need (and should) not check for it.

  Specified by:

  deserialize in class JsonDeserializer<Object>

  Parameters:

  jp - Parsed used for reading JSON content

  ctxt - Context that can be used to access information about this deserialization activity.

  Returns:

  Deserialized value

  Throws:

  IOException

  com.fasterxml.jackson.core.JsonProcessingException

• _deserializeIfNatural

  protected Object _deserializeIfNatural(com.fasterxml.jackson.core.JsonParser jp,
                             DeserializationContext ctxt)
                                  throws IOException,
                                         com.fasterxml.jackson.core.JsonProcessingException

  Throws:

  IOException

  com.fasterxml.jackson.core.JsonProcessingException

• _deserializeFromObjectId

  protected Object _deserializeFromObjectId(com.fasterxml.jackson.core.JsonParser jp,
                                DeserializationContext ctxt)
                                     throws IOException,
                                            com.fasterxml.jackson.core.JsonProcessingException

  Method called in cases where it looks like we got an Object Id to parse and use as a reference.

  Throws:

  IOException

  com.fasterxml.jackson.core.JsonProcessingException
