/**
|
|
@brief The JSON parser class.
|
|
|
|
JSON is mapped to Objective-C types in the following way:
|
|
|
|
@li Null -> NSNull
|
|
@li String -> NSMutableString
|
|
@li Array -> NSMutableArray
|
|
@li Object -> NSMutableDictionary
|
|
@li Boolean -> NSNumber (initialised with -initWithBool:)
|
|
@li Number -> (NSNumber | NSDecimalNumber)
|
|
|
|
Since Objective-C doesn't have a dedicated class for boolean values, these turns into NSNumber
|
|
instances. These are initialised with the -initWithBool: method, and
|
|
round-trip back to JSON properly. (They won't silently suddenly become 0 or 1; they'll be
|
|
represented as 'true' and 'false' again.)
|
|
|
|
As an optimisation short JSON integers turn into NSNumber instances, while complex ones turn into NSDecimalNumber instances.
|
|
We can thus avoid any loss of precision as JSON allows ridiculously large numbers.
