bool Json::Reader::parse ( const char *  beginDoc,
const char *  endDoc,
Value root,
bool  collectComments = true 
)

Read a Value from a JSON document.

Parameters:
documentUTF-8 encoded string containing the document to read.
root[out] Contains the root value of the document if it was successfully parsed.
collectCommentstrue to collect comment and allow writing them back during serialization, false to discard comments. This parameter is ignored if Features::allowComments_ is false.
Returns:
true if the document was successfully parsed, false if an error occurred.
