```
public ObjectNode deepCopy()
```
    Description copied from class: JsonNode
    
    Method that can be called to get a node that is guaranteed not to allow changing of this node through mutators on this node or any of its children. This means it can either make a copy of this node (and all mutable children and grand children nodes), or node itself if it is immutable.
    Note: return type is guaranteed to have same type as the node method is called on; which is why method is declared with local generic type.
    
    Specified by:
    
    deepCopy in class JsonNode
    
    Returns:
    
    Node that is either a copy of this node (and all non-leaf children); or, for immutable leaf nodes, node itself.
  - isEmpty
```
public boolean isEmpty(SerializerProvider serializers)
```
    Description copied from class: JsonSerializable.Base
    
    Method that may be called on instance to determine if it is considered "empty" for purposes of serialization filtering or not.
    
    Overrides:
    
    isEmpty in class JsonSerializable.Base
  - 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
  - isObject
```
public final boolean isObject()
```
    Specified by:
    
    isObject in interface TreeNode
    
    Overrides:
    
    isObject in class JsonNode
  - 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 ContainerNode<ObjectNode>
  - size
```
public int size()
```
    Specified by:
    
    size in interface TreeNode
    
    Specified by:
    
    size in class ContainerNode<ObjectNode>
  - isEmpty
```
public boolean isEmpty()
```
    Description copied from class: JsonNode
    Convenience method that is functionally same as:
```
    size() == 0
```
    for all node types.
    Overrides:
    
    isEmpty in class JsonNode
  - elements
```
public Iterator<JsonNode> elements()
```
    Description copied from class: JsonNode
    
    Method for accessing all value nodes of this Node, iff this node is a JSON Array or Object node. In case of Object node, field names (keys) are not included, only values. For other types of nodes, returns empty iterator.
    
    Overrides:
    
    elements in class JsonNode
  - get
```
public JsonNode get(int index)
```
    Description copied from class: JsonNode
    
    Method for accessing value of the specified element of an array node. For other nodes, null is always returned.
    For array nodes, index specifies exact location within array and allows for efficient iteration over child elements (underlying storage is guaranteed to be efficiently indexable, i.e. has random-access to elements). If index is less than 0, or equal-or-greater than node.size(), null is returned; no exception is thrown for any index.
    NOTE: if the element value has been explicitly set as null (which is different from removal!), a NullNode will be returned, not null.
    
    Specified by:
    
    get in interface TreeNode
    
    Specified by:
    
    get in class ContainerNode<ObjectNode>
    
    Returns:
    
    Node that represent value of the specified element, if this node is an array and has specified element. Null otherwise.
  - get
```
public JsonNode get(String fieldName)
```
    Description copied from class: JsonNode
    
    Method for accessing value of the specified field of an object node. If this node is not an object (or it does not have a value for specified field name), or if there is no field with such name, null is returned.
    NOTE: if the property value has been explicitly set as null (which is different from removal!), a NullNode will be returned, not null.
    
    Specified by:
    
    get in interface TreeNode
    
    Specified by:
    
    get in class ContainerNode<ObjectNode>
    
    Returns:
    
    Node that represent value of the specified field, if this node is an object and has value for the specified field. Null otherwise.

    Specified by:
    
    fieldNames in interface TreeNode
    
    Overrides:
    
    fieldNames in class JsonNode
  - path
```
public JsonNode path(int index)
```
    Description copied from class: JsonNode
    
    This method is similar to JsonNode.get(int), except that instead of returning null if no such element exists (due to index being out of range, or this node not being an array), a "missing node" (node that returns true for JsonNode.isMissingNode()) will be returned. This allows for convenient and safe chained access via path calls.
    
    Specified by:
    
    path in interface TreeNode
    
    Specified by:
    
    path in class JsonNode
  - path
```
public JsonNode path(String fieldName)
```
    Description copied from class: JsonNode
    
    This method is similar to JsonNode.get(String), except that instead of returning null if no such value exists (due to this node not being an object, or object not having value for the specified field), a "missing node" (node that returns true for JsonNode.isMissingNode()) will be returned. This allows for convenient and safe chained access via path calls.
    
    Specified by:
    
    path in interface TreeNode
    
    Specified by:
    
    path in class JsonNode
  - required
```
public JsonNode required(String fieldName)
```
    Description copied from class: JsonNode
    
    Method is functionally equivalent to path(fieldName).required() and can be used to check that this node is an ObjectNode (that is, represents JSON Object value) and has value for specified property with key fieldName (but note that value may be explicit JSON null value). If this node is Object Node and has value for specified property, this is returned to allow chaining; otherwise IllegalArgumentException is thrown.
    
    Overrides:
    
    required in class BaseJsonNode
    
    Returns:
    
    this node to allow chaining
  - fields
```
public Iterator<Map.Entry<String,JsonNode>> fields()
```
    Method to use for accessing all fields (with both names and values) of this JSON Object.
    
    Overrides:
    
    fields in class JsonNode
    
    Returns:
    
    Iterator that can be used to traverse all key/value pairs for object nodes; empty iterator (no contents) for other types
  - with
```
public ObjectNode with(String propertyName)
```
    Description copied from class: JsonNode
    
    Method that can be called on Object nodes, to access a property that has Object value; or if no such property exists, to create, add and return such Object node. If the node method is called on is not Object node, or if property exists and has value that is not Object node, UnsupportedOperationException is thrown
    NOTE: since 2.10 has had co-variant return type
    
    Overrides:
    
    with in class JsonNode
  - withArray
```
public ArrayNode withArray(String propertyName)
```
    Description copied from class: JsonNode
    
    Method that can be called on Object nodes, to access a property that has Array value; or if no such property exists, to create, add and return such Array node. If the node method is called on is not Object node, or if property exists and has value that is not Array node, UnsupportedOperationException is thrown
    NOTE: since 2.10 has had co-variant return type
    
    Overrides:
    
    withArray in class JsonNode
  - equals
```
public boolean equals(Comparator<JsonNode> comparator,
                      JsonNode o)
```
    Description copied from class: JsonNode
    
    Entry method for invoking customizable comparison, using passed-in Comparator object. Nodes will handle traversal of structured types (arrays, objects), but defer to comparator for scalar value comparisons. If a "natural" Comparator is passed -- one that simply calls equals() on one of arguments, passing the other -- implementation is the same as directly calling equals() on node.
    Default implementation simply delegates to passed in comparator, with this as the first argument, and other as the second argument.
    
    Overrides:
    
    equals in class JsonNode
    
    Parameters:
    
    comparator - Object called to compare two scalar JsonNode instances, and return either 0 (are equals) or non-zero (not equal)

```
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
