<brief_description>
Data class wrapper for decoded JSON.
</brief_description>
<description>
Returned by [method JSON.parse], [JSONParseResult] contains decoded JSON or error information if JSON source not successfully parsed. You can check if JSON source was successfully parsed with [code]if json_result.error == OK[/code].

<member name="error" type="int" setter="set_error" getter="get_error" enum="Error">
The error type if JSON source was not successfully parsed. See [@GlobalScope] ERR_* constants.
</member>
<member name="error_line" type="int" setter="set_error_line" getter="get_error_line">
The line number where the error occurred if JSON source was not successfully parsed.

<member name="error_string" type="String" setter="set_error_string" getter="get_error_string">
The error message if JSON source was not successfully parsed. See [@GlobalScope] ERR_* constants.

<member name="result" type="Variant" setter="set_result" getter="get_result">
A [Variant] containing the parsed JSON. Use typeof() to check if it is what you expect. For example, if JSON source starts with curly braces ([code]{}[/code]) a [Dictionary] will be returned, if JSON source starts with braces ([code][][/code]) an [Array] will be returned.
[i]Be aware that 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.[/i]
Note that 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:[/i]
[codeblock]
var p = JSON.parse('["hello", "world", "!"]')
if typeof(p.result) == TYPE_ARRAY:
print(p.result[0]) # prints 'hello'
else:
print("unexpected results")
