Constructor Summary

Constructors
Constructor and Description
`BeanAsArrayDeserializer(BeanDeserializerBase delegate, SettableBeanProperty[] ordered)` Main constructor used both for creating new instances (by `BeanDeserializer.asArrayDeserializer()`) and for creating copies with different delegate.

Method Summary

Methods
Modifier and Type	Method and Description
`protected Object`	`_deserializeFromNonArray(JsonParser jp, DeserializationContext ctxt)`
`protected Object`	`_deserializeNonVanilla(JsonParser jp, DeserializationContext ctxt)` Alternate deserialization method that has to check many more configuration aspects than the "vanilla" processing.
`protected Object`	`_deserializeUsingPropertyBased(JsonParser jp, DeserializationContext ctxt)` 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.
`protected Object`	`_deserializeWithCreator(JsonParser jp, DeserializationContext ctxt)`
`protected BeanDeserializerBase`	`asArrayDeserializer()` Fluent factory for creating a variant that can handle POJO output as a JSON Array.
`Object`	`deserialize(JsonParser jp, DeserializationContext ctxt)` Method that can be called to ask implementation to deserialize JSON content into the value type this serializer handles.
`Object`	`deserialize(JsonParser jp, DeserializationContext ctxt, Object bean)` Alternate 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.
`JsonDeserializer<Object>`	`unwrappingDeserializer(NameTransformer unwrapper)` 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.
`BeanAsArrayDeserializer`	`withIgnorableProperties(HashSet<String> ignorableProps)`
`BeanAsArrayDeserializer`	`withObjectIdReader(ObjectIdReader oir)`

    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

    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.

  - deserialize
```
public Object deserialize(JsonParser jp,
                 DeserializationContext ctxt)
                   throws IOException,
                          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:
    Deserializer value
    
    Throws:
    
    IOException
    
    JsonProcessingException
  - deserialize

public Object deserialize(JsonParser jp,

                   throws IOException,
                          JsonProcessingException
```
    Description copied from class: JsonDeserializer
    
    Alternate 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 for all supported types; most commonly it is used for Collections and Maps.
    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:
    
    deserialize in class JsonDeserializer<Object>
    
    Throws:
    
    IOException
    
    JsonProcessingException
  - _deserializeNonVanilla

                                        JsonProcessingException
```
    Alternate deserialization method that has to check many more configuration aspects than the "vanilla" processing.
    
    Throws:
    
    IOException
    
    JsonProcessingException
  - _deserializeWithCreator

                                         JsonProcessingException

  - _deserializeUsingPropertyBased
```
protected final Object _deserializeUsingPropertyBased(JsonParser jp,
                                    DeserializationContext ctxt)
                                               throws IOException,
                                                      JsonProcessingException
```
    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.
    
    Throws:
    
    IOException
    
    JsonProcessingException
  - _deserializeFromNonArray
```
protected Object _deserializeFromNonArray(JsonParser jp,

                                          JsonProcessingException
```
    Throws:
    
    IOException
    
    JsonProcessingException
