CEJSON – 5.2: The JSON Parser Function

Posted on Thursday, April 16, 2015 3:46 AM By David Jones

The Parser Function is a giant Switch-Case statement.

//The current state of the State Machine
Expecting parseState = startOfArray;

/*
Parses a JSon array of records of name value pairs
*/
BOOL ParseJsonString(char c)
{
	switch (parseState)
	{
	case startOfArray:
		result = Expect(c);
		if (result)
		{
			//Start of array so no records yet.
			RecordNo = 0;
			output.println(F("\r\n1: Starting parse of array."));
		}
   ...
   ...
   ...
    }
