Detailed Description

Json data.

The Json class represents Json data: null values, booleans, numbers, strings, and combinations of these primitives into arrays and objects.

Json objects are not references, and two Json values cannot share subobjects. This differs from Javascript. For example:

Json j1 = Json::make_object(), j2 = Json::make_object(); j1.set("a", j2); // stores a COPY of j2 in j1 j2.set("b", 1); assert(j1.unparse() == "{\"a\":{}}"); assert(j2.unparse() == "{\"b\":1}");

Compare this with the Javascript code:

var j1 = {}, j2 = {}; j1.a = j2; // stores a REFERENCE to j2 in j1 j2.b = 1; assert(JSON.stringify(j1) == "{\"a\":{\"b\":1}}");

Most Json functions for extracting components and typed values behave liberally. For example, objects silently convert to integers, and extracting properties from non-objects is allowed. This should make it easier to work with untrusted objects. (Json objects often originate from untrusted sources, and may not have the types you expect.) If you prefer an assertion to fail when a Json object has an unexpected type, use the checked as_ and at functions, rather than the liberal to_, get, and operator[] functions.

inline

Extract this object Json's value at key into x.

Parameters

[out]

x

value storage

Returns

proxy for *this

x is assigned iff contains(key). The return value is a proxy object that mostly behaves like *this. However, the proxy is "truthy" iff contains(key) and x was assigned. The proxy also has status() methods that return the extraction status. For example:

Json j = Json::parse("{\"a\":1,\"b\":2}"), x; assert(j.get("a", x)); // extraction succeeded assert(x == Json(1)); assert(!j.get("c", x)); // no "c" key assert(x == Json(1)); // x remains unchanged assert(!j.get("c", x).status()); // can use ".status()" for clarity

Can chain .get() methods to extract multiple values Json a, b, c; j.get("a", a).get("b", b); assert(a == Json(1) && b == Json(2));

Use .status() to return or assign extraction status bool a_status, b_status, c_status; j.get("a", a).status(a_status) .get("b", b).status(b_status) .get("c", c).status(c_status); assert(a_status && b_status && !c_status);

Overloaded versions of get() can extract integer, double, boolean, and string values for specific keys. These versions succeed iff contains(key) and the corresponding value has the expected type. For example:

Json j = Json::parse("{\"a\":1,\"b\":\"\"}"); int a, b; bool a_status, b_status; j.get("a", a).status(a_status).get("b", b).status(b_status); assert(a_status && a == 1 && !b_status);

back() [1/2]

const Json & Json::back ( ) const

inline

Return the last array element.

Precondition

is_array() && !empty()

back() [2/2]

Json & Json::back ( )

inline

Return a reference to the last array element.

Precondition

is_array() && !empty()

push_back()

template<typename T >

Json & Json::push_back ( T  x )

inline

Push an element onto the back of the array.

Precondition

is_array() || is_null()

Returns

this Json

A null Json is promoted to an array.

pop_back()

void Json::pop_back ( )

inline

Precondition

is_array() && !empty()

unparse() [1/5]

String Json::unparse ( ) const

inline

Return the string representation of this Json.

unparse() [2/5]

String Json::unparse ( bool  add_newline ) const

inline

Return the string representation of this Json.

Parameters

add_newline

If true, add a final newline.

unparse() [3/5]

String Json::unparse ( const unparse_manipulator &  m, bool  add_newline = false  ) const

inline

void Json::unparse

(

StringAccum &

sa

)

const
