void load(string filename)

Loads JSON from disk.

reset

void reset()

Initialises and clears the JSONValue, preparing it for object storage.

Saves the JSON storage to disk. Formatting is done as specified by the passed KeyOrderStrategy argument.

serialiseInto

void serialiseInto(Sink sink, string[] givenOrder)

Formats an object-type JSON storage into an output range sink.

serialiseInto

void serialiseInto(Sink sink)

Variables

storage

JSONValue storage;

The underlying JSONValue storage of this JSONStorage.

JSONStorage s;

s.reset();  // not always necessary

s.storage["foo"] = null;  // JSONValue quirk
s.storage["foo"]["abc"] = JSONValue(42);
s.storage["foo"]["def"] = JSONValue(3.14f);
s.storage["foo"]["ghi"] = JSONValue([ "bar", "baz", "qux" ]);
s.storage["bar"] = JSONValue("asdf");

assert(s.storage.length == 2);

import std.conv : text;
import std.json : JSONValue;

JSONStorage s;
s.reset();

s.storage["key"] = null;
s.storage["key"]["subkey1"] = "abc";
s.storage["key"]["subkey2"] = "def";
s.storage["key"]["subkey3"] = "ghi";
assert((s.storage["key"].object.length == 3), s.storage["key"].object.length.text);

s.storage["foo"] = null;
s.storage["foo"]["arr"] = JSONValue([ "blah "]);
s.storage["foo"]["arr"].array ~= JSONValue("bluh");
assert((s.storage["foo"]["arr"].array.length == 2), s.storage["foo"]["arr"].array.length.text);
