NO_NODES, NO_STRINGS| Modifier and Type | Method and Description |
|---|---|
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 valid String representation of
the container value, if the node is a value node
(method
JsonNode.isValueNode() returns true), otherwise
empty String. |
JsonToken |
asToken()
Method that can be used for efficient type detection
when using stream abstraction for traversing nodes.
|
boolean |
equals(Object o)
Equality for node objects is defined as full (deep) value
equality.
|
byte[] |
getBinaryValue()
Method to use for accessing binary content of binary nodes (nodes
for which
JsonNode.isBinary() returns true); or for Text Nodes
(ones for which JsonNode.getTextValue() returns non-null value),
to read decoded base64 data. |
Object |
getPojo()
Method that can be used to access the POJO this node wraps.
|
int |
hashCode() |
boolean |
isPojo()
Method that can be used to check if the node is a wrapper
for a POJO ("Plain Old Java Object" aka "bean".
|
void |
serialize(JsonGenerator jg,
SerializerProvider provider)
Method called to serialize node instances using given generator.
|
String |
toString()
Note: marked as abstract to ensure all implementation
classes define it properly.
