public abstract class BaseJsonNode extends JsonNode implements JsonSerializable

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

| Modifier and Type | Method and Description |
|---|---|
abstract com.fasterxml.jackson.core.JsonToken |
asToken()
Method that can be used for efficient type detection
when using stream abstraction for traversing nodes.
|
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. |
com.fasterxml.jackson.core.JsonParser.NumberType |
numberType()
Returns code that identifies type of underlying numeric
value, if (and only if) node is a number node.
|
abstract void |
serialize(com.fasterxml.jackson.core.JsonGenerator jgen,
SerializerProvider provider)
Method called to serialize node instances using given generator.
|
abstract void |
serializeWithType(com.fasterxml.jackson.core.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.

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 com.fasterxml.jackson.core.JsonParser traverse()
