Méthodes publiques

Méthode	Description
Close ( ) : void	Call this function to release all resources used by the LCM instance. After calling this function, the LCM instance should consume no resources, and cannot be used to receive or transmit messages.
LCM ( ) : System	Create a new LCM object, connecting to one or more URLs. If no URL is specified, the environment variable LCM_DEFAULT_URL is used. If that environment variable is not defined, then the default URL is used.
Publish ( string channel, LCMEncodable e ) : void	Publish an LCM-defined type on a channel. If more than one URL was specified, the message will be sent on each.
Publish ( string channel, byte data, int offset, int length ) : void	Publish raw data on a channel, bypassing the LCM type specification. If more than one URL was specified when the LCM object was created, the message will be sent on each.
Publish ( string channel, string s ) : void	Publish a string on a channel. This method does not use the LCM type definitions and thus is not type safe. This method is primarily provided for testing purposes and may be removed in the future.
Subscribe ( string regex, LCMSubscriber sub ) : void	Subscribe to all channels whose name matches the regular expression. Note that to subscribe to all channels, you must specify ".", not "".
SubscribeAll ( LCMSubscriber sub ) : void	A convenience function that subscribes to all LCM channels.
Unsubscribe ( string regex, LCMSubscriber sub ) : void	Remove this particular regex/subscriber pair (UNTESTED AND API MAY CHANGE). If regex is null, all subscriptions for 'sub' are cancelled. If subscriber is null, any previous subscriptions matching the regular expression will be cancelled. If both 'sub' and 'regex' are null, all subscriptions will be cancelled.

Private Methods

Méthode	Description
ReceiveMessage ( string channel, byte data, int offset, int length ) : void	Not for use by end users. Provider back ends call this method when they receive a message. The subscribers that match the channel name are synchronously notified.

Method Details

Close() public méthode

Call this function to release all resources used by the LCM instance. After calling this function, the LCM instance should consume no resources, and cannot be used to receive or transmit messages.

public Close ( ) : void
Résultat	void

LCM() public méthode

Create a new LCM object, connecting to one or more URLs. If no URL is specified, the environment variable LCM_DEFAULT_URL is used. If that environment variable is not defined, then the default URL is used.

public LCM ( ) : System
Résultat	System

Publish() public méthode

Publish an LCM-defined type on a channel. If more than one URL was specified, the message will be sent on each.

public Publish ( string channel, LCMEncodable e ) : void
channel	string	channel name
e	LCMEncodable	encodable object to send
Résultat	void

Publish() public méthode

Publish raw data on a channel, bypassing the LCM type specification. If more than one URL was specified when the LCM object was created, the message will be sent on each.

public Publish ( string channel, byte data, int offset, int length ) : void
channel	string	channel name
data	byte	data byte array
offset	int	offset of the data to write
length	int	length of the data to write
Résultat	void

Publish() public méthode

Publish a string on a channel. This method does not use the LCM type definitions and thus is not type safe. This method is primarily provided for testing purposes and may be removed in the future.

public Publish ( string channel, string s ) : void
channel	string	channel name
s	string	string to publich
Résultat	void

Subscribe() public méthode

Subscribe to all channels whose name matches the regular expression. Note that to subscribe to all channels, you must specify ".*", not "*".

public Subscribe ( string regex, LCMSubscriber sub ) : void
regex	string	regular expression determining the channels to subscribe
sub	LCMSubscriber	subscribing object providing callback
Résultat	void

SubscribeAll() public méthode

A convenience function that subscribes to all LCM channels.

public SubscribeAll ( LCMSubscriber sub ) : void
sub	LCMSubscriber	subscribing object providing callback
Résultat	void

Unsubscribe() public méthode

Remove this particular regex/subscriber pair (UNTESTED AND API MAY CHANGE). If regex is null, all subscriptions for 'sub' are cancelled. If subscriber is null, any previous subscriptions matching the regular expression will be cancelled. If both 'sub' and 'regex' are null, all subscriptions will be cancelled.

public Unsubscribe ( string regex, LCMSubscriber sub ) : void
regex	string	regular expression determining the channels to unsubscribe
sub	LCMSubscriber	unsubscribing object
Résultat	void
