- com.fasterxml.jackson.databind.JsonSerializable.Base
- - com.fasterxml.jackson.databind.JsonNode
  - - com.fasterxml.jackson.databind.node.BaseJsonNode
    - - com.fasterxml.jackson.databind.node.ValueNode
      - com.fasterxml.jackson.databind.node.BooleanNode

All Implemented Interfaces:

com.fasterxml.jackson.core.TreeNode, JsonSerializable, Serializable, Iterable<JsonNode>
```
public class BooleanNode
extends ValueNode
```
This concrete value class is used to contain boolean (true / false) values. Only two instances are ever created, to minimize memory usage.

  - getNodeType
```
public 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
  - asToken
```
public com.fasterxml.jackson.core.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 com.fasterxml.jackson.core.TreeNode
    
    Specified by:
    
    asToken in class ValueNode
  - booleanValue
```
public boolean booleanValue()
```
    Description copied from class: JsonNode
    
    Method to use for accessing JSON boolean values (value literals 'true' and 'false'). For other types, always returns false.
    
    Overrides:
    
    booleanValue in class JsonNode
    
    Returns:
    
    Textual value this node contains, iff it is a textual json node (comes from JSON String value entry)
  - 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 JsonNode
  - asBoolean
```
public boolean asBoolean()
```
    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), default value of false will be returned; no exceptions are thrown.
    
    Overrides:
    
    asBoolean in class JsonNode
  - 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
  - asInt
```
public int asInt(int defaultValue)
```
    Description copied from class: JsonNode
    
    Method that will try to convert value of this node to a Java int. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.
    If representation cannot be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.
    
    Overrides:
    
    asInt in class JsonNode
  - asLong
```
public long asLong(long defaultValue)
```
    Description copied from class: JsonNode
    
    Method that will try to convert value of this node to a Java long. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.
    If representation cannot be converted to a long (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.
    
    Overrides:
    
    asLong in class JsonNode
  - asDouble
```
public double asDouble(double defaultValue)
```
    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.
    If representation cannot be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.
    
    Overrides:
    
    asDouble in class JsonNode
  - serialize
```
public final void serialize(com.fasterxml.jackson.core.JsonGenerator g,
                            SerializerProvider provider)
                     throws 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:
    
    IOException
  - hashCode
```
public int hashCode()
```
    Specified by:
    
    hashCode in class BaseJsonNode
  - 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
