Detailed Description

A clock synchronisation object.

A ticker is a DUECA module that is runs by an ActivityManager. The difference with normal modules is that the Ticker blocks, waiting for a certain time. The main function of a Ticker is as a time-based trigger. One ticker is used in each DUECA node. The ticker also publishes a (local) time information channel for modules interested in more than just triggering.

Constructor & Destructor Documentation

◆ Ticker()

dueca::Ticker::Ticker ( )

Constructor.

This constructor is normally called from the scheme script.

Member Function Documentation

◆ getIncrement()

TimeTickType dueca::Ticker::getIncrement	(	double	span,
		bool	nonzero = true )

Return a time step rounded to granules.

Parameters

span	Time step to convert to granules
nonzero	If true (default), return a minimum of 1 granule.

Returns: Rounded granules in span.

◆ getUsecsSinceTick() [1/2]

int64_t dueca::Ticker::getUsecsSinceTick ( const TimeTickType & t ) const

Returns the number of microseconds elapsed.

Calculated since the tick given in ts

◆ getUsecsSinceTick() [2/2]

int64_t dueca::Ticker::getUsecsSinceTick ( const TimeSpec & ts ) const

inline

Returns the number of microseconds elapsed.

Calculated since the tick given in ts

◆ single()

static Ticker * dueca::Ticker::single ( )

inlinestatic

Make sure this class is callable from scheme.

Return a pointer to the single ticker that works in this node.

◆ getObjectType()

ObjectType dueca::Ticker::getObjectType ( ) const

inlinevirtual

The ticker is one of the base components of DUECA.

Implements dueca::NamedObject.
