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.

as well as property-based creator. |

handlePropertyValue(JsonParser jp,
DeserializationContext ctxt,

Method called to ask handler to handle value of given property,
at point where parser points to the first token of the value. |

handleTypePropertyValue(JsonParser jp,
DeserializationContext ctxt,

handleTypePropertyValue
public boolean handleTypePropertyValue(JsonParser jp,
DeserializationContext ctxt,

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
handlePropertyValue(com.fasterxml.jackson.core.JsonParser, com.fasterxml.jackson.databind.DeserializationContext, java.lang.String, java.lang.Object)
should be called instead.
- Throws:
IOException
JsonProcessingException
handlePropertyValue
public boolean handlePropertyValue(JsonParser jp,
DeserializationContext ctxt,
String propName,
Object bean)
throws IOException,
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
JsonProcessingException
complete
public Object complete(JsonParser jp,
DeserializationContext ctxt,
Object bean)
throws IOException,
JsonProcessingException
- Throws:
IOException
JsonProcessingException

throws IOException,
JsonProcessingException
- Variant called when creation of the POJO involves buffering of creator properties
as well as property-based creator.
- Throws:
