unwrappingDeserializer
public JsonDeserializer<Object> unwrappingDeserializer(NameTransformer unwrapper)
Description copied from class:JsonDeserializerMethod 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

Description copied from class:BeanDeserializerBaseMutant factory method that custom sub-classes must override; not left as abstract to prevent more drastic backwards compatibility problems.- Overrides:

-
asArrayDeserializer
protected BeanDeserializerBase asArrayDeserializer()
Description copied from class:BeanDeserializerBaseFluent factory for creating a variant that can handle POJO output as a JSON Array. Implementations may ignore this request if no such input is possible.- Specified by:
asArrayDeserializerin classBeanDeserializerBase
-
supportsUpdate
public Boolean supportsUpdate(DeserializationConfig config)
Description copied from class:JsonDeserializerIntrospection method that may be called to see whether deserializer supports update of an existing value (aka "merging") or not. Return value should either beBoolean.FALSEif update is not supported at all (immutable values);Boolean.TRUEif update should usually work (regular POJOs, for example), ornullif this is either not known, or may sometimes work.Information gathered is typically used to either prevent merging update for property (either by skipping, if based on global defaults; or by exception during deserialization construction if explicit attempt made) if
Boolean.FALSEreturned, or inclusion ifBoolean.TRUEis specified. If "unknown" case (nullreturned) behavior is to exclude property if global defaults used; or to allow if explicit per-type or property merging is defined.Default implementation returns
nullto allow explicit per-type or per-property attempts.- Overrides:

deserialize
public Object deserialize(com.fasterxml.jackson.core.JsonParser p, DeserializationContext ctxt) throws IOException
Description copied from class:JsonDeserializerMethod 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 or a FIELD_NAME.
The two possible input conditions for structured types result from polymorphism via fields. In the ordinary case, Jackson calls this method when it has encountered an OBJECT_START, and the method implementation must advance to the next token to see the first field name. If the application configures polymorphism via a field, then the object looks like the following.
{ "@class": "class name", ... }Jackson consumes the two tokens (the @class field name and its value) in order to learn the class and select the deserializer. Thus, the stream is pointing to the FIELD_NAME for the first field after the @class. Thus, if you want your method to work correctly both with and without polymorphism, you must begin your method with:if (p.currentToken() == JsonToken.START_OBJECT) { p.nextToken(); }This results in the stream pointing to the field name, so that the two conditions align.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.

deserialize
public Object deserialize(com.fasterxml.jackson.core.JsonParser p, DeserializationContext ctxt, Object value) throws IOException
Description copied from class:JsonDeserializerAlternate deserialization method (compared to the most commonly used,JsonDeserializer.deserialize(JsonParser, DeserializationContext)), which takes in initialized value instance, to be configured and/or populated by deserializer. Method is not necessarily used (or supported) by all types (it will not work for immutable types, for obvious reasons): most commonly it is used for Collections and Maps. It may be used both with "updating readers" (for POJOs) and when Collections and Maps use "getter as setter".Default implementation just throws
UnsupportedOperationException, to indicate that types that do not explicitly add support do not necessarily support update-existing-value operation (esp. immutable types)- Overrides:

deserializeFromObject
public Object deserializeFromObject(com.fasterxml.jackson.core.JsonParser p, DeserializationContext ctxt) throws IOException
Description copied from class:BeanDeserializerBaseGeneral version used when handling needs more advanced features.- Specified by:

IOException
-
_deserializeNonVanilla
protected Object _deserializeNonVanilla(com.fasterxml.jackson.core.JsonParser p, DeserializationContext ctxt) throws IOException
Alternate deserialization method that has to check many more configuration aspects than the "vanilla" processing. Note: should NOT resolve builder; caller will do that- Returns:
- Builder object in use.
- Throws:
IOException
-
_deserializeUsingPropertyBased
protected final Object _deserializeUsingPropertyBased(com.fasterxml.jackson.core.JsonParser p, DeserializationContext ctxt) throws IOException
Method called to deserialize bean using "property-based creator": this means that a non-default constructor or factory method is called, and then possibly other setters. The trick is that values for creator method need to be buffered, first; and due to non-guaranteed ordering possibly some other properties as well.- Specified by:

IOException

_deserializeFromNonArray
