Detailed Description

A parser turns a stream of bytes into one stream of "events" per YAML document in the input stream.

Constructor & Destructor Documentation

Parser() [1/2]

YAML::Parser::Parser

(

)

Constructs an empty parser (with no input.

Parser() [2/2]

YAML::Parser::Parser ( std::istream &  in )

explicit

Constructs a parser from the given input stream.

The input stream must live as long as the parser.

Member Function Documentation

HandleNextDocument()

bool YAML::Parser::HandleNextDocument

(

EventHandler &

eventHandler

)

Handles the next document by calling events on the.

eventHandler 

.

Exceptions

a	ParserException on error.

Returns

false if there are no more documents

HandleTagDirective()

void YAML::Parser::HandleTagDirective ( const Token &  token )

private

Handles a "TAG" directive, which should be of the form 'handle prefix', where 'handle' is converted to 'prefix' in the file.

HandleYamlDirective()

void YAML::Parser::HandleYamlDirective ( const Token &  token )

private

Handles a "YAML" directive, which should be of the form 'major.minor' (like a version number).

Load()

void YAML::Parser::Load

(

std::istream &

in

)

Resets the parser with the given input stream.

Any existing state is erased.

operator bool()

YAML::Parser::operator bool ( ) const

explicit

Evaluates to true if the parser has some valid input to be read.

ParseDirectives()

void YAML::Parser::ParseDirectives ( )

private

Reads any directives that are next in the queue, setting the internal.

m_pDirectives 

state.
