C# Class Amazon.Runtime.Internal.Transform.JsonUnmarshallerContext

Wraps a json string for unmarshalling. Each Read() operation gets the next token. TestExpression() is used to match the current key-chain to an xpath expression. The general pattern looks like this:

 JsonUnmarshallerContext context = new JsonUnmarshallerContext(jsonString); while (context.Read()) { if (context.IsKey) { if (context.TestExpresion("path/to/element")) { myObject.stringMember = stringUnmarshaller.GetInstance().Unmarshall(context); continue; } } }

Public Methods

Method	Description
JsonUnmarshallerContext ( Stream responseStream, bool maintainResponseBody, IWebResponseData responseData ) : System	Wrap the jsonstring for unmarshalling.
Peek ( JsonToken token ) : bool	Peeks at the next token. This peek implementation reads the next token and makes the subsequent Read() return the same data. If Peek is called successively, it will return the same data. Only the first one calls Read(), subsequent calls will return the same data until a Read() call is made.
Peek ( ) : int	Peeks at the next (non-whitespace) character in the jsonStream.
Read ( ) : bool	Reads to the next token in the json document, and updates the context accordingly.
ReadText ( ) : string	Returns the text contents of the current token being parsed.

Protected Methods

Method	Description
Dispose ( bool disposing ) : void

Private Methods

Method	Description
StreamPeek ( ) : int	Peeks at the next character in the stream. If the data isn't buffered into the StreamReader (Peek() returns -1), we flush the buffered data and try one more time.
UpdateContext ( ) : void
