Constructor used by BeanDeserializerBuilder.

BeanDeserializer
```

Method Detail

unwrappingDeserializer
```
public JsonDeserializer<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

Specified by:

unwrappingDeserializer in class BeanDeserializerBase

withObjectIdReader
```
public BeanDeserializer withObjectIdReader(ObjectIdReader oir)
```
Specified by:

withObjectIdReader in class BeanDeserializerBase

withIgnorableProperties
```
public BeanDeserializer withIgnorableProperties(HashSet<String> ignorableProps)
```
Specified by:

withIgnorableProperties in class BeanDeserializerBase

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:

asArrayDeserializer in class BeanDeserializerBase

deserialize
```
public Object deserialize(JsonParser p,
                 DeserializationContext ctxt)
                   throws IOException
```
Main deserialization method for bean-based objects (POJOs).
NOTE: was declared 'final' in 2.2; should NOT be to let extensions like Afterburner change definition.

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

_deserializeOther

protected final Object _deserializeOther(JsonParser p,
                       DeserializationContext ctxt,
                       JsonToken t)
                                  throws IOException

Throws:: IOException

_missingToken

protected Object _missingToken(JsonParser p,
                   DeserializationContext ctxt)
                        throws IOException

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

_deserializeUsingPropertyBased
```
protected Object _deserializeUsingPropertyBased(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 class BeanDeserializerBase

Throws:

IOException
