Modifier and Type | Method and Description |
---|---|
boolean |
asBoolean()
Method that will try to convert value of this node to a Java boolean.
|
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. |
com.fasterxml.jackson.core.JsonToken |
asToken()
Method that can be used for efficient type detection
when using stream abstraction for traversing nodes.
|
boolean |
booleanValue()
Method to use for accessing JSON boolean values (value
literals 'true' and 'false').
|
boolean |
equals(Object o)
Equality for node objects is defined as full (deep) value
equality.
|
static BooleanNode |
getFalse() |
JsonNodeType |
getNodeType()
Return the type of this node
|

getTrue() |
void |
serialize(com.fasterxml.jackson.core.JsonGenerator jg,
SerializerProvider provider)
Method called to serialize node instances using given generator.

If representation can not be converted to a boolean value (including structured types like Objects and Arrays), default value of false will be returned; no exceptions are thrown.
public boolean asBoolean(boolean defaultValue)
JsonNode
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.
public int asInt(int defaultValue)
JsonNode
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.
public long asLong(long defaultValue)
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.
public double asDouble(double defaultValue)
JsonNode
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.
