public class POJONode extends ValueNode
ObjectMapper
).JsonSerializable.Base
Modifier and Type | Method and Description |
---|---|
protected boolean |
_pojoEquals(POJONode other) |
boolean |
asBoolean(boolean defaultValue)
Method that will try to convert value of this node to a Java boolean.
|
double |
asDouble(double defaultValue)
Method that will try to convert value of this node to a Java double.
|
int |
asInt(int defaultValue)
Method that will try to convert value of this node to a Java int.
|
long |
asLong(long defaultValue)
Method that will try to convert value of this node to a Java long.
|
String |
asText()
Method that will return a valid String representation of
the container value, if the node is a value node
(method
JsonNode.isValueNode() returns true),
otherwise empty String. |
String |
asText(String defaultValue)
Method similar to
JsonNode.asText() , except that it will return
defaultValue in cases where null value would be returned;
either for missing nodes (trying to access missing property, or element
at invalid item for array) or explicit nulls. |
JsonToken |
asToken()
Method that can be used for efficient type detection
when using stream abstraction for traversing nodes.
|
byte[] |
binaryValue()
As it is possible that some implementations embed byte[] as POJONode
(despite optimal being
BinaryNode ), let's add support for exposing
binary data here too. |
boolean |
equals(Object o)
Equality for node objects is defined as full (deep) value
equality.
|
JsonNodeType |
getNodeType()
Return the type of this node
|
Object |
getPojo()
Method that can be used to access the POJO this node wraps.
|
int |
hashCode() |
void |
serialize(JsonGenerator gen,
SerializerProvider serializers)
Method called to serialize node instances using given generator.
|
String |
toString()
Method that will produce developer-readable representation of the
node; which may or may not be as valid JSON.

If representation can not be converted to a boolean value (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

If representation can not be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

JsonNode
If representation can not be converted to an long (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.
