JSONParseResult

Inherits: Reference < Object

Data class wrapper for decoded JSON.

Description

Returned by JSON.parse, JSONParseResult contains the decoded JSON or error information if the JSON source wasn't successfully parsed. You can check if the JSON source was successfully parsed with if json_result.error == OK.

Properties

Error error
int error_line -1
String error_string ""
Variant result

Property Descriptions

Error error

Setter set_error(value)
Getter get_error()

The error type if the JSON source was not successfully parsed. See the Error constants.

int error_line

Default -1
Setter set_error_line(value)
Getter get_error_line()

The line number where the error occurred if the JSON source was not successfully parsed.

String error_string

Default ""
Setter set_error_string(value)
Getter get_error_string()

The error message if the JSON source was not successfully parsed. See the Error constants.

Variant result

Setter set_result(value)
Getter get_result()

A Variant containing the parsed JSON. Use @GDScript.typeof or the is keyword to check if it is what you expect. For example, if the JSON source starts with curly braces ({}), a Dictionary will be returned. If the JSON source starts with brackets ([]), an Array will be returned.

Note: The JSON specification does not define integer or float types, but only a number type. Therefore, parsing a JSON text will convert all numerical values to float types.

Note: JSON objects do not preserve key order like Godot dictionaries, thus, you should not rely on keys being in a certain order if a dictionary is constructed from JSON. In contrast, JSON arrays retain the order of their elements:

var p = JSON.parse('["hello", "world", "!"]')
if typeof(p.result) == TYPE_ARRAY:
    print(p.result[0]) # Prints "hello"
else:
    push_error("Unexpected results.")
