JsonNode Class
The JsonNode
class is a versatile class designed to work with JSON-like data structures. It provides a set of methods to navigate, manipulate, and extract information from JSON data. This class is particularly useful for handling and processing JSON data within your applications.
Methods
get(property: String): JsonNode
:
This method is used to retrieve a nested property (key) from the JSON-like data, returning a new JsonNode
representing the specified property.
asText(): String
:
It returns the content of the JsonNode
as a string, assuming the content is textual.
asInt(): Integer
:
This method converts the JsonNode
to an integer value if it's numeric; otherwise, it may throw an error or return a default value.
asBoolean(): Boolean
:
Converts the JsonNode
to a Boolean value if it's a valid boolean value; otherwise, it may throw an error or return a default value.
isObject(): Boolean
:
Checks if the JsonNode
represents a JSON object and returns true
if it is an object, otherwise false
.
isArray(): Boolean
:
Similar to isObject
, this method checks if the JsonNode
represents a JSON array and returns true
if it is an array, otherwise false
.
isNumber(): Boolean
:
Determines if the JsonNode
represents a numeric value and returns true
if it's numeric, otherwise false
.
isBoolean(): Boolean
:
Checks if the JsonNode
represents a Boolean value and returns true
if it's a boolean, otherwise false
.
isNull(): Boolean
:
Checks if the JsonNode
is null and returns true
if it's null, otherwise false
.
isTextual(): Boolean
:
Determines if the JsonNode
contains textual data and returns true
if it's textual, otherwise false
.
toPrettyString(): String
:
This method returns a nicely formatted, pretty-printed string representation of the JSON data contained in the JsonNode
.
toString(): String
:
Returns a string representation of the JSON data contained in the JsonNode
.
hasNonNull(filed: String): Boolean
:
Checks if the JsonNode
contains a non-null field with the specified name and returns true
if it exists and is not null, otherwise false
.
