  - getNodeType
```
public final JsonNodeType getNodeType()
```
    Description copied from class: JsonNode
    
    Return the type of this node
    
    Specified by:
    
    getNodeType in class JsonNode
    
    Returns:
    
    the node type as a JsonNodeType enum value
  - numberType
```
public abstract 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
    
    Overrides:
    
    numberType in class BaseJsonNode
    
    Returns:
    
    Type of number contained, if any; or null if node does not contain numeric value.
  - numberValue
```
public abstract java.lang.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
    
    Overrides:
    
    numberValue in class JsonNode
    
    Returns:
    
    Number value this node contains, if any (null for non-number nodes).
  - intValue
```
public abstract 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.
    
    Overrides:
    
    intValue in class JsonNode
    
    Returns:
    
    Integer value this node contains, if any; 0 for non-number nodes.
  - longValue
```
public abstract 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.
    
    Overrides:
    
    longValue in class JsonNode
    
    Returns:
    
    Long value this node contains, if any; 0 for non-number nodes.
  - doubleValue
```
public abstract 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.
    
    Overrides:
    
    doubleValue in class JsonNode
    
    Returns:
    
    64-bit double value this node contains, if any; 0.0 for non-number nodes.
  - decimalValue
```
public abstract java.math.BigDecimal decimalValue()
```
    Description copied from class: JsonNode
    
    Returns floating point value for this node (as BigDecimal), if and only if this node is numeric (JsonNode.isNumber() returns true). For other types returns BigDecimal.ZERO.
    
    Overrides:
    
    decimalValue in class JsonNode
    
    Returns:
    
    BigDecimal value this node contains, if numeric node; BigDecimal.ZERO for non-number nodes.
  - bigIntegerValue
```
public abstract java.math.BigInteger bigIntegerValue()
```
    Description copied from class: JsonNode
    
    Returns integer value for this node (as BigInteger), if and only if this node is numeric (JsonNode.isNumber() returns true). For other types returns BigInteger.ZERO.
    NOTE: In Jackson 2.x MAY throw StreamConstraintsException if the scale of the underlying BigDecimal is too large to convert (NOTE: thrown "sneakily" in Jackson 2.x due to API compatibility restrictions)
    
    Overrides:
    
    bigIntegerValue in class JsonNode
    
    Returns:
    
    BigInteger value this node contains, if numeric node; BigInteger.ZERO for non-number nodes.
  - canConvertToInt
```
public abstract 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.
    
    Overrides:
    
    canConvertToInt in class JsonNode
  - canConvertToLong
```
public abstract 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.
    
    Overrides:
    
    canConvertToLong in class JsonNode
  - asText
```
public abstract 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.

  - asInt
```
public final int asInt()
```
    Description copied from class: JsonNode

  - asDouble
```
public final double asDouble()
```
    Description copied from class: JsonNode
    
    Method that will try to convert value of this node to a Java double. Numbers are coerced using default Java rules; booleans convert to 0.0 (false) and 1.0 (true), and Strings are parsed using default Java language integer parsing rules.
