方法详细资料

valueOf

public static DoubleNode valueOf(double v)

asToken

public JsonToken asToken()

从类复制的说明: 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)

指定者:

asToken 在类中 ValueNode

getNumberType

public JsonParser.NumberType getNumberType()

从类复制的说明: JsonNode

If this node is a numeric type (as per JsonNode.isNumber()), returns native type that node uses to store the numeric value.

指定者:

getNumberType 在类中 NumericNode

isFloatingPointNumber

public boolean isFloatingPointNumber()

覆盖:

isFloatingPointNumber 在类中 JsonNode

返回:

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

isDouble

public boolean isDouble()

覆盖:

isDouble 在类中 JsonNode

getNumberValue

public Number getNumberValue()

从类复制的说明: JsonNode

Returns numeric value for this node, if and only if this node is numeric (JsonNode.isNumber() returns true); otherwise returns null

指定者:

getNumberValue 在类中 NumericNode

返回:

Number value this node contains, if any (null for non-number nodes).

getIntValue

public int getIntValue()

从类复制的说明: 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.

指定者:

getIntValue 在类中 NumericNode

返回:

Integer value this node contains, if any; 0 for non-number nodes.

getLongValue

public long getLongValue()

指定者:

getLongValue 在类中 NumericNode

getDoubleValue

public double getDoubleValue()

指定者:

getDoubleValue 在类中 NumericNode

getDecimalValue

public BigDecimal getDecimalValue()

指定者:

getDecimalValue 在类中 NumericNode

getBigIntegerValue

public BigInteger getBigIntegerValue()

指定者:

getBigIntegerValue 在类中 NumericNode

asText

public String asText()

从类复制的说明: 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.

指定者:

asText 在类中 NumericNode

serialize

public final void serialize(JsonGenerator jg,
             SerializerProvider provider)
                     throws IOException,
                            JsonProcessingException

从类复制的说明: BaseJsonNode

Method called to serialize node instances using given generator.

指定者:

serialize 在接口中 JsonSerializable

指定者:

serialize 在类中 BaseJsonNode

抛出:

IOException

JsonProcessingException

equals

public boolean equals(Object o)

从类复制的说明: 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.

指定者:

equals 在类中 JsonNode

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object
