asToken()
Method that can be used for efficient type detection when using stream abstraction for traversing nodes. |

int |
getIntValue()
Returns integer value for this node, if and only if this node is numeric ( JsonNode.isNumber() returns true). |
long |
getLongValue()
|
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. |
Number |
getNumberValue()
Returns numeric value for this node, if and only if this node is numeric ( JsonNode.isNumber() returns true); otherwise
returns null |
String |
getValueAsText()
Method that will return valid String representation of the container value, if the node is a value node (method JsonNode.isValueNode() returns true), otherwise null. |

one token but for structured/container types multiple)

value.

getNumberValue
in class NumericNode
public int getIntValue()
JsonNode
JsonNode.isNumber()
returns true). For other
types returns 0.
For floating-point numbers, value is truncated using default
Java coercion, similar to how cast from double to int operates.

Note: to serialize nodes of any type, you should call

instead.
