Link< TI, TAR > Struct Template Reference

#include "lib/time/control-policy.hpp"

Description

template<class TI, class TAR>
struct lib::time::mutation::Link< TI, TAR >

Policy to tie the various detail policies together for providing actual value change operations.

The standard case uses the (inherited) time::Mutation base implementation to impose a new value onto the target entity and then uses the Builder policy to create a notification value reflecting this change.

Static Public Member Functions inherited from Mutation
static EncapsulatedMutation	changeTime (Time)
	Convenience factory to yield a simple Mutation changing the absolute start time.
static EncapsulatedMutation	changeDuration (Duration)
	Convenience factory: simple Mutation to adjust the duration or length of a timespan.
static EncapsulatedMutation	adjust (Offset)
	Convenience factory: simple Mutation to adjust the duration or length of a timespan.
static EncapsulatedMutation	materialise (QuTime const &)
	Convenience factory: materialise the given quantised time into an explicit fixed internal time value, according to the underlying time grid; impose the resulting value then as new time point or start point to the target.
static EncapsulatedMutation	nudge (int adjustment)
	build a time mutation to nudge the target time value by an offset, defined as number of steps on an implicit nudge grid.
static EncapsulatedMutation	nudge (int adjustment, Symbol gridID)
	build a time mutation to nudge the target time value in steps based on a pre-defined grid.
