Class ExternalTypeHandler

java.lang.Object
  com.fasterxml.jackson.databind.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.

handlePropertyValue

public boolean handlePropertyValue(com.fasterxml.jackson.core.JsonParser jp,
                                   DeserializationContext ctxt,
                                   String propName,
                                   Object bean)
                            throws IOException,
                                   com.fasterxml.jackson.core.JsonProcessingException

Method called to ask handler to handle value of given property, at point where parser points to the first token of the value. Handling can mean either resolving type id it contains (if it matches type property name), or by buffering the value for further use.

Returns:

True, if the given property was properly handled

Throws:

IOException

com.fasterxml.jackson.core.JsonProcessingException
