public TextNode(String v)
```
- Method Detail
  - valueOf
```
public static TextNode valueOf(String v)
```
    Factory method that should be used to construct instances. For some common cases, can reuse canonical instances: currently this is the case for empty Strings, in future possible for others as well. If null is passed, will return null.
    
    Returns:
    
    Resulting TextNode object, if v is NOT null; null if it is.
  - 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
  - textValue
```
public String textValue()
```
    Description copied from class: JsonNode
    
    Method to use for accessing String values. Does NOT do any conversions for non-String value nodes; for non-String values (ones for which JsonNode.isTextual() returns false) null will be returned. For String values, null is never returned (but empty Strings may be)
    
    Overrides:
    
    textValue in class JsonNode
    
    Returns:
    
    Textual value this node contains, iff it is a textual JSON node (comes from JSON String value entry)
  - getBinaryValue
```
public byte[] getBinaryValue(com.fasterxml.jackson.core.Base64Variant b64variant)
                      throws IOException
```
    Method for accessing textual contents assuming they were base64 encoded; if so, they are decoded and resulting binary data is returned.
    
    Throws:
    
    IOException
  - binaryValue
```
public byte[] binaryValue()
                   throws IOException
```
    Description copied from class: JsonNode
    
    Method to use for accessing binary content of binary nodes (nodes for which JsonNode.isBinary() returns true); or for Text Nodes (ones for which JsonNode.textValue() returns non-null value), to read decoded base64 data. For other types of nodes, returns null.
    
    Overrides:
    
    binaryValue in class JsonNode
    
    Returns:
    
    Binary data this node contains, iff it is a binary node; null otherwise
    
    Throws:
    
    IOException
  - 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
  - asText
```
@Deprecated
public String asText(String defaultValue)
```
    Deprecated.
    
    Description copied from class: JsonNode
    
    Method similar to JsonNode.asText(), except that it will return defaultValue in cases where null value would be returned; either for missing nodes (trying to access missing property, or element at invalid item for array) or explicit nulls.
    NOTE: deprecated since 2.17 because JsonNode.asText() very rarely returns null for any node types -- in fact, neither MissingNode nor NullNode return null from JsonNode.asText().
    
    Overrides:
    
    asText 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
  - 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
  - hashCode
```
public int hashCode()
```
    Specified by:
    
    hashCode in class BaseJsonNode
  - appendQuoted
```
@Deprecated
protected static void appendQuoted(StringBuilder sb,
                                               String content)
```
    Deprecated.
