```
  - 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
    
    Returns:
    
    JsonToken that is most closely associated with the node type
  - 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.
  - 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()
```
    Description copied from class: JsonNode
    
    Method that can be used to check whether contained value is a number represented as Java long. Note, however, that even if this method returns false, it is possible that conversion would be possible from other numeric types -- to check if this is possible, use JsonNode.canConvertToLong() instead.
    
    Overrides:
    
    isLong in class JsonNode
    
    Returns:
    
    True if the value contained by this node is stored as Java long
  - 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)
    NOTE: this method does not consider possible value type conversion from JSON String into Number; so even if this method returns false, it is possible that JsonNode.asInt() could still succeed if node is a JSON String representing integral number, or boolean.
    
    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)
    NOTE: this method does not consider possible value type conversion from JSON String into Number; so even if this method returns false, it is possible that JsonNode.asLong() could still succeed if node is a JSON String representing integral number, or boolean.
    
    Specified by:
    
    canConvertToLong in class NumericNode
  - numberValue
```
public java.lang.Number numberValue()
```

    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).

```
public short shortValue()
```
    Description copied from class: JsonNode
    
    Returns 16-bit short 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 short operates.
    
    Overrides:
    
    shortValue in class JsonNode
    
    Returns:
    
    Short value this node contains, if any; 0 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()
```
    Description copied from class: JsonNode
    
    Returns 64-bit long 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 long operates.
    
    Specified by:
    
    longValue in class NumericNode
    
    Returns:
    
    Long value this node contains, if any; 0 for non-number nodes.
  - floatValue
```
public float floatValue()
```
    Description copied from class: JsonNode
    
    Returns 32-bit floating value for this node, if and only if this node is numeric (JsonNode.isNumber() returns true). For other types returns 0.0. For integer values, conversion is done using coercion; this means that an overflow is possible for `long` values
    
    Overrides:
    
    floatValue in class JsonNode
    
    Returns:
    
    32-bit float value this node contains, if any; 0.0 for non-number nodes.

public double doubleValue()
```
    Description copied from class: JsonNode
    
    Returns 64-bit floating point (double) value for this node, if and only if this node is numeric (JsonNode.isNumber() returns true). For other types returns 0.0. For integer values, conversion is done using coercion; this may result in overflows with BigInteger values.
    
    Specified by:
    
    doubleValue in class NumericNode
    
    Returns:
    
    64-bit double value this node contains, if any; 0.0 for non-number nodes.

public java.math.BigDecimal decimalValue()
```
    Description copied from class: JsonNode

    Specified by:
    
    decimalValue in class NumericNode
    
    Returns:
    
    BigDecimal value this node contains, if numeric node; BigDecimal.ZERO for non-number nodes.
  - bigIntegerValue
```
public java.math.BigInteger bigIntegerValue()
```
    Description copied from class: JsonNode
    
    Returns integer value for this node (as BigDecimal), if and only if this node is numeric (JsonNode.isNumber() returns true). For other types returns BigInteger.ZERO.
    
    Specified by:
    
    bigIntegerValue in class NumericNode
    
    Returns:
    
    BigInteger value this node contains, if numeric node; BigInteger.ZERO for non-number nodes.
  - asText
```
public java.lang.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
  - 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 cannot 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 g,
                            SerializerProvider provider)
                     throws java.io.IOException
```
    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
  - 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()
```
    Specified by:
    
    hashCode in class BaseJsonNode
