Modifier and Type | Method and Description |
---|---|
boolean |
asBoolean(boolean defaultValue)
Method that will try to convert value of this node to a Java boolean.
|
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. |
JsonToken |
asToken()
Method that can be used for efficient type detection
when using stream abstraction for traversing nodes.
|
BigInteger |
bigIntegerValue()
Returns integer value for this node (as
BigDecimal ), if and only if
this node is numeric (JsonNode.isNumber() returns true). |
boolean |
canConvertToInt()
Method that can be used to check whether this node is a numeric
node (
JsonNode.isNumber() would return true) AND its value fits
within Java's 32-bit signed integer type, int . |
boolean |
canConvertToLong()
Method that can be used to check whether this node is a numeric
node (
JsonNode.isNumber() would return true) AND its value fits
within Java's 64-bit signed integer type, long . |
BigDecimal |
decimalValue()
Returns floating point value for this node (as
BigDecimal ), if and only if
this node is numeric (JsonNode.isNumber() returns true). |
double |
doubleValue()
Returns 64-bit floating point (double) value for this node, if and only if
this node is numeric (
JsonNode.isNumber() returns true). |
boolean |
equals(Object o)
Equality for node objects is defined as full (deep) value
equality.
|
float |
floatValue()
Returns 32-bit floating value for this node, if and only if
this node is numeric (
JsonNode.isNumber() returns true). |
int |
hashCode() |
int |
intValue()
Returns integer value for this node, if and only if
this node is numeric (
JsonNode.isNumber() returns true). |
boolean |
isIntegralNumber() |
boolean |
isShort()
Method that can be used to check whether contained value
is a number represented as Java
short . |
long |
longValue()
Returns 64-bit long value for this node, if and only if
this node is numeric (
JsonNode.isNumber() returns true). |
JsonParser.NumberType |
numberType()
Returns code that identifies type of underlying numeric
value, if (and only if) node is a number node.
|
Number |
numberValue()
Returns numeric value for this node, if and only if
this node is numeric (
JsonNode.isNumber() returns true); otherwise
returns null |
void |
serialize(JsonGenerator jg,
SerializerProvider provider)
Method called to serialize node instances using given generator.
|
short |
shortValue()
Returns 16-bit short value for this node, if and only if
this node is numeric (
JsonNode.isNumber() returns true). |

Note, however, that even if this method returns false, it
is possible that conversion would be possible from other numeric
types -- to check if this is possible, use

instead.public boolean canConvertToInt()

Note that floating-point numbers are convertible if the integral
part fits without overflow (as per standard Java coercion rules)
NOTE: this method does not consider possible value type conversion
from JSON String into Number; so even if this method returns false,
it is possible that JsonNode.asInt()
could still succeed
if node is a JSON String representing integral number, or boolean.
