implementations.
The main addition here is that we declare that sub-classes must
implement JsonSerializableWithType.
This simplifies object mapping
aspects a bit, as no external serializers are needed.NO_NODES, NO_STRINGS| Modifier | Constructor and Description |

BaseJsonNode() |
| Modifier and Type | Method and Description |
|---|---|
abstract JsonToken |
asToken()
Method that can be used for efficient type detection
when using stream abstraction for traversing nodes.
|
ObjectNode |
findParent(String fieldName)
Method for finding a JSON Object that contains specified field,
within this node or its descendants.
|
List<JsonNode> |
findParents(String fieldName,
List<JsonNode> foundSoFar) |
JsonNode |
findPath(String fieldName)
Method similar to
JsonNode.findValue(java.lang.String), but that will return a
"missing node" instead of null if no field is found. |
JsonNode |
findValue(String fieldName)
Method for finding a JSON Object field with specified name in this
node or its child nodes, and returning value it has.
|
List<JsonNode> |
findValues(String fieldName,
List<JsonNode> foundSoFar) |
List<String> |
findValuesAsText(String fieldName,
List<String> foundSoFar) |
JsonParser.NumberType |
getNumberType()
If this node is a numeric type (as per
JsonNode.isNumber()),
returns native type that node uses to store the numeric
value. |
abstract void |
serialize(JsonGenerator jgen,
SerializerProvider provider)
Method called to serialize node instances using given generator.
|
abstract void |
serializeWithType(JsonGenerator jgen,
SerializerProvider provider,
TypeSerializer typeSer)
Type information is needed, even if JsonNode instances are "plain" JSON,
since they may be mixed with other types.
|
JsonParser |
traverse()
Method for constructing a
JsonParser instance for
iterating over contents of the tree that this
node is root of. |

JsonNodeJsonNode.findValue(java.lang.String), but that will return a
"missing node" instead of null if no field is found. Missing node
is a specific kind of node for which JsonNode.isMissingNode()
returns true; and all value access methods return empty or
missing value.public ObjectNode findParent(String fieldName)

Functionally equivalent to first serializing tree using
ObjectCodec and then re-parsing but
more efficient.public abstract JsonToken asToken()
JsonToken that equivalent
stream event would produce (for most nodes there is just
one token but for structured/container types multiple)public JsonParser.NumberType getNumberType()
JsonNodeJsonNode.isNumber()),
returns native type that node uses to store the numeric
value.getNumberType in class JsonNodepublic abstract void serialize(JsonGenerator jgen, SerializerProvider provider) throws IOException, JsonProcessingException
