Method Summary

Modifier and Type	Method	Description
Object	deserialize(JsonParser p, DeserializationContext ctxt)	Main deserialization method for bean-based objects (POJOs).
Object	deserialize(JsonParser p, DeserializationContext ctxt, Object bean)	Secondary deserialization method, called in cases where POJO instance is created as part of deserialization, potentially after collecting some or all of the properties to set.
Object	deserializeFromObject(JsonParser p, DeserializationContext ctxt)	General version used when handling needs more advanced features.
JsonDeserializer<Object>	unwrappingDeserializer(NameTransformer transformer)	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.
BeanDeserializerBase	withBeanProperties(BeanPropertyMap props)	Mutant factory method that custom sub-classes must override; not left as abstract to prevent more drastic backwards compatibility problems.
BeanDeserializer	withByNameInclusion(Set<String> ignorableProps, Set<String> includableProps)
BeanDeserializerBase	withIgnoreAllUnknown(boolean ignoreUnknown)
BeanDeserializer	withObjectIdReader(ObjectIdReader oir)

Method Details

unwrappingDeserializer

public JsonDeserializer<Object> unwrappingDeserializer(NameTransformer transformer)

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

Specified by:

unwrappingDeserializer in class BeanDeserializerBase

withObjectIdReader

public BeanDeserializer withObjectIdReader(ObjectIdReader oir)

Specified by:

withObjectIdReader in class BeanDeserializerBase

withByNameInclusion

public BeanDeserializer withByNameInclusion(Set<String> ignorableProps,
 Set<String> includableProps)

Specified by:

withByNameInclusion in class BeanDeserializerBase

withIgnoreAllUnknown

public BeanDeserializerBase withIgnoreAllUnknown(boolean ignoreUnknown)

Specified by:

withIgnoreAllUnknown in class BeanDeserializerBase

withBeanProperties

public BeanDeserializerBase withBeanProperties(BeanPropertyMap props)

Description copied from class: BeanDeserializerBase

Mutant factory method that custom sub-classes must override; not left as abstract to prevent more drastic backwards compatibility problems.

Overrides:

withBeanProperties in class BeanDeserializerBase

deserialize

public Object deserialize(JsonParser p,
 DeserializationContext ctxt)
                   throws IOException

Main deserialization method for bean-based objects (POJOs).

Specified by:

deserialize in class JsonDeserializer<Object>

Parameters:

p - Parsed used for reading JSON content

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

Returns:

Deserialized value

Throws:

IOException

deserialize

public Object deserialize(JsonParser p,
 DeserializationContext ctxt,
 Object bean)
                   throws IOException

Secondary deserialization method, called in cases where POJO instance is created as part of deserialization, potentially after collecting some or all of the properties to set.

Overrides:

deserialize in class JsonDeserializer<Object>

Throws:

IOException

deserializeFromObject

public Object deserializeFromObject(JsonParser p,
 DeserializationContext ctxt)
                             throws IOException

General version used when handling needs more advanced features.

Specified by:

deserializeFromObject in class BeanDeserializerBase

Throws:

IOException
