    • _at

      protected JsonNode _at(JsonPointer ptr)
      Description copied from class: JsonNode
      Helper method used by other methods for traversing the next step of given path expression, and returning matching value node if any: if no match, null is returned.
      Specified by:
      _at in class JsonNode
      Parameters:
      ptr - Path expression to use
      Returns:
      Either matching JsonNode for the first step of path or null if no match (including case that this node is not a container)

    • deepCopy

      public ArrayNode 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.

    • with

      @Deprecated public ObjectNode with(String exprOrProperty)
      Deprecated.
      Description copied from class: JsonNode
      Method that works in one of possible ways, depending on whether exprOrProperty is a valid JsonPointer expression or not (valid expression is either empty String "" or starts with leading slash / character). If it is, works as a short-cut to: 
        withObject(JsonPointer.compile(exprOrProperty));
      If it is NOT a valid JsonPointer expression, value is taken as a literal Object property name and traversed like a single-segment JsonPointer.

      NOTE: before Jackson 2.14 behavior was always that of non-expression usage; that is, exprOrProperty was always considered as a simple property name.

      Overrides:
      with in class JsonNode

    • withArray

      public ArrayNode withArray(String exprOrProperty)
      Description copied from class: JsonNode
      Method that works in one of possible ways, depending on whether exprOrProperty is a valid JsonPointer expression or not (valid expression is either empty String "" or starts with leading slash / character). If it is, works as a short-cut to: 
        withObject(JsonPointer.compile(exprOrProperty));
      If it is NOT a valid JsonPointer expression, value is taken as a literal Object property name and traversed like a single-segment JsonPointer.

      NOTE: before Jackson 2.14 behavior was always that of non-expression usage; that is, exprOrProperty was always considered as a simple property name.

      Overrides:
      withArray in class JsonNode
      Parameters:
      exprOrProperty - Either JsonPointer expression for full access (if valid pointer expression), or the name of property for the ArrayNode.
      Returns:
      ArrayNode found or created

    • isArray

      public boolean isArray()
      Description copied from interface: TreeNode
      Method that returns true if this node is an Array node, false otherwise. Note that if true is returned, TreeNode.isContainerNode() must also return true.
      Specified by:
      isArray in interface TreeNode

      Specified by:
      size in interface TreeNode
      Specified by:
      size in class ContainerNode<ArrayNode>
      Returns:
      For non-container nodes returns 0; for arrays number of contained elements, and for objects number of fields.

    • 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<ArrayNode>
      Parameters:
      index - Index of the Array node element to access
      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<ArrayNode>
      Parameters:
      fieldName - Name of the field (of Object node) to access
      Returns:
      Node that represent value of the specified field, if this node is an object and has value for the specified field. Null otherwise.

    • 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
      Parameters:
      fieldName - Name of the field (of Object node) to access
      Returns:
      Node that represent value of the specified field, if this node is an object and has value for the specified field; otherwise "missing node" is returned.

    • 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
      Parameters:
      index - Index of the Array node element to access
      Returns:
      Node that represent value of the specified element, if this node is an array and has specified element; otherwise "missing node" is returned.

    • required

      public JsonNode required(int index)
      Description copied from class: JsonNode
      Method is functionally equivalent to path(index).required() and can be used to check that this node is an ArrayNode (that is, represents JSON Array value) and has value for specified index (but note that value may be explicit JSON null value). If this node is Array Node and has value for specified index, value at index is returned; otherwise IllegalArgumentException is thrown.
      Overrides:
      required in class BaseJsonNode
      Parameters:
      index - Index of the value of this Array node to access
      Returns:
      Value at specified index of this Array node

    • 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)

    • serializeWithType

      public void serializeWithType(JsonGenerator g, SerializerProvider provider, TypeSerializer typeSer) throws IOException
      Description copied from class: BaseJsonNode

      Specified by:
      serializeWithType in interface JsonSerializable
      Specified by:
      serializeWithType in class BaseJsonNode
