Field Details

_nodeFactory

protected final JsonNodeFactory _nodeFactory

We will keep a reference to the Object (usually TreeMapper) that can construct instances of nodes to add to this container node.

Constructor Details

ContainerNode

protected ContainerNode(JsonNodeFactory nc)

ContainerNode

protected ContainerNode()

Method Details

asToken

public abstract 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 BaseJsonNode

Returns:

JsonToken that is most closely associated with the node type

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

size

public abstract int size()

Description copied from interface: TreeNode

Method that returns number of child nodes this node contains: for Array nodes, number of child elements, for Object nodes, number of fields, and for all other nodes 0.

Specified by:

size in interface TreeNode

Overrides:

size in class JsonNode

Returns:

For non-container nodes returns 0; for arrays number of contained elements, and for objects number of fields.

get

public abstract 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 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. Null otherwise.

get

public abstract 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

Overrides:

get 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. Null otherwise.

_withObject

protected abstract ObjectNode _withObject(JsonPointer origPtr,
 JsonPointer currentPtr,
 JsonNode.OverwriteMode overwriteMode,
 boolean preferIndex)

Overrides:

_withObject in class BaseJsonNode

booleanNode

public final BooleanNode booleanNode(boolean v)

Specified by:

booleanNode in interface JsonNodeCreator

missingNode

public JsonNode missingNode()

nullNode

public final NullNode nullNode()

Specified by:

nullNode in interface JsonNodeCreator

arrayNode

public final ArrayNode arrayNode()

Factory method that constructs and returns an empty ArrayNode Construction is done using registered JsonNodeFactory.

Specified by:

arrayNode

public final ArrayNode arrayNode(int capacity)

Factory method that constructs and returns an ArrayNode with an initial capacity Construction is done using registered JsonNodeFactory

Specified by:

arrayNode in interface JsonNodeCreator

Parameters:

capacity - the initial capacity of the ArrayNode

objectNode

public final ObjectNode objectNode()

Factory method that constructs and returns an empty ObjectNode Construction is done using registered JsonNodeFactory.

Specified by:

objectNode in interface JsonNodeCreator

Specified by:

numberNode in interface JsonNodeCreator

pojoNode

public final ValueNode pojoNode(Object pojo)

Specified by:

pojoNode in interface JsonNodeCreator

rawValueNode

public final ValueNode rawValueNode(RawValue value)

Description copied from interface: JsonNodeCreator

Factory method to use for adding "raw values"; pre-encoded values that are included exactly as-is when node is serialized. This may be used, for example, to include fully serialized JSON sub-trees. Note that the concept may not work with all backends, and since no translation of any kinds is done it will not work when converting between data formats.

Specified by:

rawValueNode in interface JsonNodeCreator

removeAll

public abstract T removeAll()

Method for removing all children container has (if any)

Returns:

Container node itself (to allow method call chaining)
