Detailed Description

Base class for all parser items.

The key method of the parser base class is the std::string parse(const std::string&) method. Parser proxy derivatives which overwrite any of the other parse() methods to be the key method must make sure that the original parse() method utilizes the new key method.

Constructor & Destructor Documentation

base_t() [1/3]

MHAParser::base_t::base_t

(

const std::string &

h

)

Constructor for base class of all parser nodes.

Parameters

h	Help text describing this parser node. This help text is accessible to the configuration language through the "?help" query command.

base_t() [2/3]

MHAParser::base_t::base_t

(

const base_t &

src

)

Copy constructor for base_t.

Copies help text and id string, but does not insert the new node into the parser tree structure.

Parameters

Deprecated:

Copying parser nodes makes little sense, avoid wherever possible

Member Data Documentation

writeaccess

MHAEvents::emitter_t MHAParser::base_t::writeaccess

Event emitted on write access.

To connect a callback that is invoked on write access to this parser variable, use MHAEvents::patchbay_t<receiver_t> method connect(&writeaccess,&receiver_t::callback) where callback is a method that expects no parameters and returns void.

valuechanged

MHAEvents::emitter_t MHAParser::base_t::valuechanged

Event emitted if the value has changed.

To connect a callback that is invoked when write access to this parser variable actually changes its value, use MHAEvents::patchbay_t<receiver_t> method connect(&valuechanged,&receiver_t::callback) where callback is a method that expects no parameters and returns void.

readaccess

MHAEvents::emitter_t MHAParser::base_t::readaccess

Event emitted on read access.

To connect a callback that is invoked after the value of this variable has been read through the configuration interface, use MHAEvents::patchbay_t<receiver_t> method connect(&readaccess,&receiver_t::callback) where callback is a method that expects no parameters and returns void.

prereadaccess

MHAEvents::emitter_t MHAParser::base_t::prereadaccess

Event emitted on read access, before the data field is accessed.

To connect a callback that is invoked when the value of this variable is about to be read through the configuration interface, so that the callback can influence the value that is reported, use MHAEvents::patchbay_t<receiver_t> method connect(&prereadaccess,&receiver_t::callback) where callback is a method that expects no parameters and returns void.
