Json Parser¶

import "std/text/json-parser";

JsonParser struct¶

Recursive-descent JSON parser.

Use parseJson for one-shot parsing; the struct is exposed mainly so the parser state (position, error message) can be inspected when needed.

The JsonValue data model lives in "std/text/json/json-value" and serialization in "std/text/json/json-serializer".

Constructors¶

ctor¶

1

public p JsonParser.ctor(const String& input)

Construct a JSON parser over the given input string

Parameters

Methods¶

parse¶

1

public f<Result<JsonValue*>> JsonParser.parse()

Parse the input string into a JSON value tree

Returns: Result<JsonValue*> — Result holding the root JSON value, or an error if the input is malformed

Functions¶

parseJson¶

1

public f<Result<JsonValue*>> parseJson(const String& input)

Parse a JSON document.

On success returns the root JsonValue, which the caller owns and releases again with deleteJsonValue from "std/text/json/json-value". On failure the partially built tree is released by the parser and an error describing the first problem encountered is returned.

Parameters

Returns: Result<JsonValue*>
