nlohmann::json_pointer::operator/¶

// (1)
json_pointeroperator/(constjson_pointer&lhs,constjson_pointer&rhs);
// (2)
json_pointeroperator/(constjson_pointer&lhs,string_ttoken);
// (3)
json_pointeroperator/(constjson_pointer&lhs,std::size_tarray_idx);

1. create a new JSON pointer by appending the right JSON pointer at the end of the left JSON pointer
2. create a new JSON pointer by appending the unescaped token at the end of the JSON pointer
3. create a new JSON pointer by appending the array-index-token at the end of the JSON pointer

Parameters¶

lhs (in)

JSON pointer

rhs (in)

JSON pointer to append

token (in)

reference token to append

array_idx (in)

array index to append

Return value¶

1. a new JSON pointer with rhs appended to lhs
2. a new JSON pointer with unescaped token appended to lhs
3. a new JSON pointer with array_idx appended to lhs

Complexity¶

1. Linear in the length of lhs and rhs.
2. Linear in the length of lhs.
3. Linear in the length of lhs.

Examples¶

#include<iostream>
#include<nlohmann/json.hpp>
usingjson=nlohmann::json;
intmain()
{
// create a JSON pointer
json::json_pointerptr("/foo");
// append a JSON Pointer
std::cout<<"\""<<ptr/json::json_pointer("/bar/baz")<<"\"\n";
// append a string
std::cout<<"\""<<ptr/"fob"<<"\"\n";
// append an array index
std::cout<<"\""<<ptr/42<<"\""<<std::endl;
}

"/foo/bar/baz"
"/foo/fob"
"/foo/42"
