DoubleNode

public DoubleNode(double v)

Method Detail

valueOf

public static DoubleNode valueOf(double v)

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

isFloatingPointNumber

public boolean isFloatingPointNumber()

Overrides:

isFloatingPointNumber in class JsonNode

Returns:

True if this node represents a non-integral numeric Json value

isDouble

public boolean isDouble()

Overrides:

isDouble in class JsonNode

getNumberValue

public java.lang.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 java.math.BigDecimal getDecimalValue()

Specified by:

getDecimalValue in class NumericNode

getBigIntegerValue

public java.math.BigInteger getBigIntegerValue()

Specified by:

getBigIntegerValue in class NumericNode

asText

public java.lang.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

serialize

public final void serialize(JsonGenerator jg,
                            SerializerProvider provider)
                     throws java.io.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:

java.io.IOException

JsonProcessingException

equals

public boolean equals(java.lang.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 java.lang.Object
