double |
asDouble()
Method that will try to convert value of this node to a Java double.
|
double |
asDouble(double defaultValue)
Method that will try to convert value of this node to a Java double.
|
int |
asInt()
Method that will try to convert value of this node to a Java int.
|
int |
asInt(int defaultValue)
Method that will try to convert value of this node to a Java int.
|
long |
asLong()
Method that will try to convert value of this node to a Java long.
|
long |
asLong(long defaultValue)
Method that will try to convert value of this node to a Java long.
|
abstract 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. |
abstract BigInteger |
getBigIntegerValue() |
abstract BigDecimal |
getDecimalValue() |
abstract double |
getDoubleValue() |
abstract int |
getIntValue()
Returns integer value for this node, if and only if
this node is numeric (
JsonNode.isNumber() returns true). |
abstract long |
getLongValue() |
abstract 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. |
abstract Number |
getNumberValue()
Returns numeric value for this node, if and only if
this node is numeric (
JsonNode.isNumber() returns true); otherwise
returns null |

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.getIntValue
