Constructor Detail

LongNode

public LongNode(long v)
Method Detail

valueOf

public static LongNode valueOf(long l)

asToken

public JsonToken asToken()
Description copied from class: BaseJsonNode
Method that can be used for efficient type detection when using stream abstraction for traversing nodes. Will return the first JsonToken that equivalent stream event would produce (for most nodes there is just one token but for structured/container types multiple)

Specified by:
asToken in class ValueNode

getNumberType

public JsonParser.NumberType getNumberType()
Description copied from class: JsonNode
If this node is a numeric type (as per JsonNode.isNumber()), returns native type that node uses to store the numeric value.

Specified by:
getNumberType in class NumericNode

isIntegralNumber

public boolean isIntegralNumber()
Overrides:
isIntegralNumber in class JsonNode
Returns:
True if this node represents an integral (integer) numeric Json value

isLong

public boolean isLong()
Overrides:
isLong in class JsonNode
Returns:
True if this node represents an integral numeric Json value that fits in Java long value space (but not int value space, i.e. JsonNode.isInt() returns false)

getNumberValue

public Number getNumberValue()
Description copied from class: JsonNode
Returns numeric value for this node, if and only if this node is numeric (JsonNode.isNumber() returns true); otherwise returns null

Specified by:
getNumberValue in class NumericNode
Returns:
Number value this node contains, if any (null for non-number nodes).

getIntValue

public int getIntValue()
Description copied from class: JsonNode
Returns integer value for this node, if and only if this node is numeric (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.

Specified by:
getIntValue in class NumericNode
Returns:
Integer value this node contains, if any; 0 for non-number nodes.

getLongValue

public long getLongValue()
Specified by:
getLongValue in class NumericNode

getDoubleValue

public double getDoubleValue()
Specified by:
getDoubleValue in class NumericNode

getDecimalValue

public BigDecimal getDecimalValue()
Specified by:
getDecimalValue in class NumericNode

getBigIntegerValue

public BigInteger getBigIntegerValue()
Specified by:
getBigIntegerValue in class NumericNode

asText

public String asText()
Description copied from class: JsonNode
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.

Specified by:
asText in class NumericNode

asBoolean

public boolean asBoolean(boolean defaultValue)
Description copied from class: JsonNode
Method that will try to convert value of this node to a Java boolean. JSON booleans map naturally; integer numbers other than 0 map to true, and 0 maps to false and Strings 'true' and 'false' map to corresponding values.

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.

Overrides:
asBoolean in class JsonNode

serialize

public final void serialize(JsonGenerator jg,
                            SerializerProvider provider)
                     throws IOException,
                            JsonProcessingException
Description copied from class: BaseJsonNode
Method called to serialize node instances using given generator.

Specified by:
serialize in interface JsonSerializable
Specified by:
serialize in class BaseJsonNode
Throws:
IOException
JsonProcessingException

equals

public boolean equals(Object o)
Description copied from class: JsonNode
Equality for node objects is defined as full (deep) value equality. This means that it is possible to compare complete JSON trees for equality by comparing equality of root nodes.

Note: marked as abstract to ensure all implementation classes define it properly and not rely on definition from Object.

Specified by:
equals in class JsonNode

hashCode

public int hashCode()
Overrides:
hashCode in class Object
