addProperty

protected void addProperty(String propertyName,
               BeanPropertyDeserializer<T,B,?> deserializer)

Add a BeanPropertyDeserializer

Parameters:

propertyName - name of the property

deserializer - deserializer

addProperty

protected void addProperty(String referenceName,
               BackReferenceProperty<T,?> backReference)

Add a BackReferenceProperty

Parameters:

referenceName - name of the reference

backReference - backReference

addIgnoredProperty

protected void addIgnoredProperty(String propertyName)

Add an ignored property

Parameters:

propertyName - name of the property

doDeserialize

public T doDeserialize(JsonReader reader,
              JsonDeserializationContext ctx)
                throws IOException

Description copied from class: JsonDeserializer

Deserializes a non-null JSON input into an object.

Specified by:

doDeserialize in class JsonDeserializer<T>

Parameters:

reader - JsonReader used to read the JSON input

ctx - Context for the full deserialization process

Returns:

the deserialized object

Throws:

IOException - if an error occurs reading the input

deserializeObject

                  JsonDeserializationContext ctx)
                          throws IOException

Deserializes all the properties of the bean. The JsonReader must be in a json object.

Parameters:

reader - reader

ctx - context of the deserialization process

Throws:

IOException - if an error occurs while reading a property

Description copied from class: JsonDeserializer

Set the back reference.

Overrides:

setBackReference in class JsonDeserializer<T>

Parameters:

referenceName - name of the reference

reference - reference to set

value - value to set the reference to.

ctx - Context for the full deserialization process
