Function std.json.JSONValue.this

Constructor for JSONValue. If arg is a JSONValue its value and type will be copied to the new JSONValue. Note that this is a shallow copy: if type is JSONType.object or JSONType.array then only the reference to the data will be copied. Otherwise, arg must be implicitly convertible to one of the following types: typeof(null), string, ulong, long, double, an associative array V[K] for any V and K i.e. a JSON object, any array or bool. The type will be set accordingly.

this(T) (
  T arg
if (!isStaticArray!T);

this(T) (
  ref T arg
if (isStaticArray!T);

inout this(T) (
  inout T arg


JSONValue j = JSONValue( "a string" );
j = JSONValue(42);

j = JSONValue( [1, 2, 3] );
writeln(j.type); // JSONType.array

j = JSONValue( ["language": "D"] );
writeln(j.type); // JSONType.object
