Json.opBinaryRight - multiple declarations

Function Json.opBinaryRight

Performs binary operations between JSON values.


							
					Json opBinaryRight(string op)
					(
					

					  bool other
					

					) const;
					

					

					Json opBinaryRight(string op)
					(
					

					  long other
					

					) const @trusted;
					

					

					Json opBinaryRight(string op)
					(
					

					  BigInt other
					

					) const @trusted;
					

					

					Json opBinaryRight(string op)
					(
					

					  double other
					

					) const;
					

					

					Json opBinaryRight(string op)
					(
					

					  string other
					

					) const @trusted
					

					if (op == "~");
					

					

					Json opBinaryRight(string op)
					(
					

					  Json[] other
					

					) @trusted;

The two JSON values must be of the same run time type or a JSONException will be thrown. Only the operations listed are allowed for each of the types.

Null: none
Bool: &&, ||
Int: +, -, *, /, %
Float: +, -, *, /, %
String: ~
Array: ~
Object: in

Function Json.opBinaryRight

Checks wheter a particular key is set and returns a pointer to it.


							
					inout inout(Json)* opBinaryRight(string op)
					(
					

					  string other
					

					) @trusted
					

					if (op == "in");

For field that don't exist or have a type of Type.undefined, the in operator will return null.

Example

auto j = Json.emptyObject;
j["a"] = "foo";
j["b"] = Json.undefined;

assert("a" in j);
assert(("a" in j).get!string == "foo");
assert("b" !in j);
assert("c" !in j);
