Method Detail
-
valueOf
public static IntNode valueOf(int i)
-
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 firstJsonToken
that equivalent stream event would produce (for most nodes there is just one token but for structured/container types multiple)
-
getNumberType
public JsonParser.NumberType getNumberType()
Description copied from class:JsonNode
If this node is a numeric type (as perJsonNode.isNumber()
), returns native type that node uses to store the numeric value.- Specified by:
getNumberType
in classNumericNode
-
isIntegralNumber
public boolean isIntegralNumber()
- Overrides:
isIntegralNumber
in classJsonNode
- Returns:
- True if this node represents an integral (integer) numeric Json value
-
isInt
public boolean isInt()
-
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 classNumericNode
- 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 classNumericNode
- Returns:
- Integer value this node contains, if any; 0 for non-number nodes.
-
getLongValue
public long getLongValue()
- Specified by:
getLongValue
in classNumericNode
-
getDoubleValue
public double getDoubleValue()
- Specified by:
getDoubleValue
in classNumericNode
-
getDecimalValue
public java.math.BigDecimal getDecimalValue()
- Specified by:
getDecimalValue
in classNumericNode
-
getBigIntegerValue
public java.math.BigInteger getBigIntegerValue()
- Specified by:
getBigIntegerValue
in classNumericNode
-
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 (methodJsonNode.isValueNode()
returns true), otherwise empty String.- Specified by:
asText
in classNumericNode
-
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.
-
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 interfaceJsonSerializable
- Specified by:
serialize
in classBaseJsonNode
- 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
