JsonNode.isMissingNode() ) will be returned. |
JsonNode |
path(String fieldName)
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. |

|
String |
toString()
Method that will produce developer-readable representation of the
node; which may or may not be as valid JSON.

public JsonNode get(int index)
JsonNode
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.

JsonNode
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.
