double PositionDB::getDistance	(	nsaddr_t	srcid,
		nsaddr_t	dstid
	)

distance of two items (in the original intention, nodes indexed by MAC addresses)

Parameters:

	srcid	index of src
	dstid	index of dst

Returns:

the distance as per Position::getDist()

int PositionDB::command	(	int	argc,
		const char *const *	argv
	)			[virtual]

TCL command interpreter. It implements the following OTcl methods:

• Id_ < >: return the id of the PlugIn
• Id_ <integer id value>: set the PlugIn id to the requested value
• addclsap <ClSAP instance>: initializes the clSap_ pointer to the given ClSAP
• addbin <Bin instance>: initializes the binPtr_ pointer to the given Bin
• settag <tag string>: initializes the tag_ class attribute

Moreover it inherits all the OTcl method of NsObject

Parameters:

	argc	number of arguments in argv
	argv	array of strings which are the comand parameters (Note that argv[0] is the name of the object)

Returns:

TCL_OK or TCL_ERROR whether the command has been dispatched succesfully or no

(

ClMessage *

m

)

[virtual]

Cross-Layer messages synchronous interpreter. It has to be properly extended in order to interpret custom cross-layer messages used by this particular plug-in. This type of communication need to be directly answered in the message exchanged in order to be synchronous with the source.

Parameters:

m

an instance of ClMessage that represent the message received and used for the answer

Returns:

zero if successful
