These three functiosn can be used to query the state later. Done means that a call to Process will immediately return 1 Error if Process threw an exception last Ok if everything looks good (Process never been called, or last return 0 or possibly -1)
Implemented in libvariant::EventBuffer, libvariant::JSONParserImpl, libvariant::XMLPLISTParserImpl, libvariant::YAMLParserImpl, libvariant::BundleHdrParserImpl, and libvariant::MsgPackParserImpl.

inlinevirtual |
Pop the top ParserActions handler off the action handler stack and return it.
|
inlinevirtual |
Push a new ParserActions handler onto the action handler stack.
|
pure virtual |
Attempt to parse some actions. At least one ParserActions should be on the action stack.
Run is not guaranteed to be recursively callable from inside a ParserActions callback. Do not do that.
return 0 on success return 1 when done return -1 if needing more data is detected (not all parsers support this; can be treated as an error) throw on error
Implemented in libvariant::EventBuffer, libvariant::JSONParserImpl, libvariant::XMLPLISTParserImpl, libvariant::YAMLParserImpl, libvariant::BundleHdrParserImpl, and libvariant::MsgPackParserImpl.
