asArrayDeserializer
protected BeanDeserializerBase asArrayDeserializer()
Description copied from class:BeanDeserializerBase
Fluent 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:

deserialize
public Object deserialize(com.fasterxml.jackson.core.JsonParser p, DeserializationContext ctxt) throws IOException
Main deserialization method for bean-based objects (POJOs).- Specified by:
deserialize
in classJsonDeserializer<Object>
- Parameters:
p
- Parsed used for reading JSON contentctxt
- Context that can be used to access information about this deserialization activity.- Returns:
- Deserialized value
- Throws:
IOException

deserialize
in classJsonDeserializer<Object>
- Throws:

in classBeanDeserializerBase
- Throws:
IOException
-
_deserializeUsingPropertyBased
protected 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:
_deserializeUsingPropertyBased
in classBeanDeserializerBase
- Throws:
IOException
-
_deserializeWithErrorWrapping
protected final Object _deserializeWithErrorWrapping(com.fasterxml.jackson.core.JsonParser p, DeserializationContext ctxt, SettableBeanProperty prop) throws IOException
- Throws:
IOException
-
deserializeFromNull
protected Object deserializeFromNull(com.fasterxml.jackson.core.JsonParser p, DeserializationContext ctxt) throws IOException
Helper method called for rare case of pointing toJsonToken.VALUE_NULL
token. While this is most often an erroneous condition, there is one specific case with XML handling where polymorphic type with no properties is exposed as such, and should be handled same as empty Object.- Throws:
IOException
- Since:
- 2.7
