Member Function Documentation

void ola::web::JsonPatchParser::Number ( const JsonDouble::DoubleRepresentation rep)
virtual

Called when a double value is encountered.

MinGW struggles with long doubles http://mingw.5.n7.nabble.com/Strange-behaviour-of-gcc-4-8-1-with-long-double-td32949.html To avoid this, and to keep as many significant bits as possible we keep the components of a double separate. See JsonDouble for details.

Implements ola::web::JsonParserInterface.

void ola::web::JsonPatchParser::ObjectKey ( const std::string &  key)
virtual

Called when a new key is encountered.

This may be called multiple times for the same object. The standard doesn't specify how to handle duplicate keys, so I generally use the last one.

Implements ola::web::JsonParserInterface.

bool ola::web::JsonPatchParser::Parse ( const std::string &  input,
JsonPatchSet patch_set,
std::string *  error 
)
static

Build a JsonPatchSet from a JSON document.

Parameters
inputthe JSON text to parse
patch_setthe JsonPatchSet to populate
errorwhere to store any errors.
void ola::web::JsonPatchParser::String ( const std::string &  value)
virtual

Called when a string is encountered.

This is not called for object keys, see ObjectKey() below.

Implements ola::web::JsonParserInterface.
