parseJsonSax

bool parseJsonSax(const(char)[]  input,  ref  JsonSaxHandler handler,  out  JsonError err,
       const  JsonPolicy policy =  JsonPolicy.init)

@safe

Parse JSON text and emit SAX-style events into handler.

This parser uses the lexer and does not build a full var tree. It is intended for memory-efficient processing of large documents.

Parameters

`input`	The JSON text to parse.
`handler`	The event handler receiving parsing events.
`err`	Output parameter for error information on failure.
`policy`	Policy controlling parser behavior.

Returns

true on success; false with err populated on failure.

Examples

import ddn.data.json : JsonSaxHandler, parseJsonSax, JsonError;
import ddn.var : var;

size_t keys = 0;
size_t scalars = 0;
JsonSaxHandler h;
h.onKey = (const string k) @safe { ++keys; };
h.onValue = (const var v) @safe { ++scalars; };

JsonError err;
assert(parseJsonSax(`{"a":1,"b":[2,3]}`, h, err));
assert(keys == 2);
assert(scalars == 3);
