Class ExternalTypeHandler

java.lang.Object

org.codehaus.jackson.map.deser.impl.ExternalTypeHandler

public class ExternalTypeHandler
extends Object

Helper class that is used to flatten JSON structure when using "external type id" (see JsonTypeInfo.As.EXTERNAL_PROPERTY). This is needed to store temporary state and buffer tokens, as the structure is rearranged a bit so that actual type deserializer can resolve type and finalize deserialization.

Since:

1.9

ExternalTypeHandler

protected ExternalTypeHandler(org.codehaus.jackson.map.deser.impl.ExternalTypeHandler.ExtTypedProperty[] properties,
                   HashMap<String,Integer> nameToPropertyIndex,
                   String[] typeIds,

Method Detail

start

public ExternalTypeHandler start()

handleTypePropertyValue

public boolean handleTypePropertyValue(JsonParser jp,
                              DeserializationContext ctxt,
                              String propName,
                              Object bean)
                                throws IOException,
                                       JsonProcessingException

Method called to see if given property/value pair is an external type id; and if so handle it. This is only to be called in case containing POJO has similarly named property as the external type id; otherwise handleToken(org.codehaus.jackson.JsonParser, org.codehaus.jackson.map.DeserializationContext, java.lang.String, java.lang.Object) should be called instead.

Throws:

IOException

JsonProcessingException

handleToken

public boolean handleToken(JsonParser jp,
                  DeserializationContext ctxt,
                  String propName,
                  Object bean)
                    throws IOException,
                           JsonProcessingException

Method called to ask handler to handle

Throws:

IOException

JsonProcessingException

complete

              DeserializationContext ctxt,
              Object bean)
                throws IOException,
                       JsonProcessingException

Throws:

IOException

_deserialize

protected final void _deserialize(JsonParser jp,
                DeserializationContext ctxt,
