Method Summary

Methods
Modifier and Type	Method and Description
`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()`
`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()`
`double`	`doubleValue()`
`boolean`	`equals(Object o)` Equality for node objects is defined as full (deep) value equality.
`int`	`hashCode()`
`int`	`intValue()` Returns integer value for this node, if and only if this node is numeric (`JsonNode.isNumber()` returns true).
`boolean`	`isDouble()`
`boolean`	`isFloatingPointNumber()`
`long`	`longValue()`
`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.
`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 interface TreeNode
    
    Specified by:
    
    asToken in class ValueNode
  - numberType
```
public JsonParser.NumberType numberType()
```
    Description copied from class: BaseJsonNode
    
    Returns code that identifies type of underlying numeric value, if (and only if) node is a number node.
    
    Specified by:
    
    numberType in interface TreeNode
    
    Specified by:
    
    numberType in class NumericNode
    
    Returns:
    Type of number contained, if any; or null if node does not contain numeric value.
  - 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
  - canConvertToInt
```
public boolean canConvertToInt()
```
    Description copied from class: JsonNode
    
    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. Note that floating-point numbers are convertible if the integral part fits without overflow (as per standard Java coercion rules)
    
    Specified by:
    
    canConvertToInt in class NumericNode
  - canConvertToLong
```
public boolean canConvertToLong()
```
    Description copied from class: JsonNode
    
    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. Note that floating-point numbers are convertible if the integral part fits without overflow (as per standard Java coercion rules)
    
    Specified by:
    
    canConvertToLong in class NumericNode
  - numberValue
```
public Number numberValue()
```
    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:
    
    numberValue in class NumericNode
    
    Returns:
    Number value this node contains, if any (null for non-number nodes).
  - intValue
```
public int intValue()
```
    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:
    
    intValue in class NumericNode
    
    Returns:
    Integer value this node contains, if any; 0 for non-number nodes.
  - longValue
```
public long longValue()
```
    Specified by:
    
    longValue in class NumericNode
  - doubleValue
```
public double doubleValue()
```
    Specified by:
    
    doubleValue in class NumericNode
  - decimalValue

public BigDecimal decimalValue()

public BigInteger bigIntegerValue()
```

    bigIntegerValue in class NumericNode
  - asText
```
public String asText()
```
    Description copied from class: JsonNode
    
    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.
    
    Specified by:
    
    asText in class NumericNode
  - serialize
```
public final void serialize(JsonGenerator jg,
             SerializerProvider provider)

                            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
