◆ readFromBlob()

bool Document::readFromBlob ( StringRef  Blob,

function_ref< int(DocNode *DestNode, DocNode SrcNode, DocNode MapKey)>  Merger = [](DocNode *DestNode, DocNode SrcNode, DocNode MapKey) { return -1; } 
)

Read a document from a binary msgpack blob, merging into anything already in the Document.

The blob data must remain valid for the lifetime of this Document (because a string object in the document contains a StringRef into the original blob). If Multi, then this sets root to an array and adds top-level objects to it. If !Multi, then it only reads a single top-level object, even if there are more, and sets root to that. Returns false if failed due to illegal format or merge error.

The Merger arg is a callback function that is called when the merge has a conflict, that is, it is trying to set an item that is already set. If the conflict cannot be resolved, the callback function returns -1. If the conflict can be resolved, the callback returns a non-negative number and sets *DestNode to the resolved node. The returned non-negative number is significant only for an array node; it is then the array index to start populating at. That allows Merger to choose whether to merge array elements (returns 0) or append new elements (returns existing size).

If SrcNode is an array or map, the resolution must be that *DestNode is an array or map respectively, although it could be the array or map (respectively) that was already there. MapKey is the key if *DestNode is a map entry, a nil node otherwise.

The default for Merger is to disallow any conflict.
