Examples of JsonStreamReader

AND

It handles a few extra things that are not supported in the spec. These are:

-Strings can be quoted with ' or " (spec says only ")

-Keys in maps/objects can be unquoted (spec says they must be quoted)
e.g. foo : 'bar' or 'foo' : 'bar' or "foo" : "bar" are all acceptable.

-Supports a few escape sequences that the spec doesn't mention : \', \0, \v

-Javascript functions can be values in maps or arrays. These are only supported when they are in the format of function(arg1,arg2){}. Named functions are not supported, as in json the names are supplied as the key in a map instead. functions will be returned as lib.json.JsonFunction objects.

-Binary streams in Salesforce.com's JSON+binary format are supported, which uses the backtick character as a delimiter and the format:
`[length of data in bytes as a 64-bit big-endian binary number][raw binary data]`
This is enabled only when a JsonStreamReader is constructed using an InputStream.

===============

default json->java mappings:
json object(map) ==> java.util.HashMap
json String==> java.lang.String
json Number==> java.math.BigDecimal
json boolean==> boolean
json null==> null
json array==> java.util.ArrayList<Object>
js function==> lib.json.JsFunction
json binary==> java.io.InputStream

If you want to provide your own mappings (rather than those above), you can pass in your own implementation of JsonHandlerProvider, and then your JsonHandlers will be used. This allows you to skip the intermediate step of parsing into Maps and Lists, and lets you put the primitives directly into your objects as they are parsed.
