Well, mine too. It does have to tokenize so it knows when it finds something you want it to parse,


I have other ways of finding something. I switch to a fast matching algorithm where I basically look for a quote as if the document were a flat stream of characters and not a hierarchical ordered structure of logical JSON elements. That's what I mean by partial parsing and part of what I mean by denormalized searching/scanning.

It ignores swaths of the document until it finds what you want. For example
C++
reader.skipToField("name",JsonReader::Forward);


This performs the type of flat match that I'm talking about.

C++
reader.skipToField("name",JsonReader::Siblings);


This performs a partially flat and partially structured match, looking for name on this level of the object heirarchy.

C++
reader.skipToField("name",JsonReader::Descendants);


This does a nearly flat match, but basically counts '{' and '}' so it knows when to stop searching.

I've simplified the explanation of what I've done, but that's the gist. I also don't load strings into memory at all when comparing them. I compare one character at a time straight off the "disk" so I never know the whole field name unless it's the one I'm after.
