Returns:

double

Implements de::constraint.

Here is the call graph for this function:

double de::real_constraint::get_rand_value

(

)

[inline, virtual]

returns a random value limited to the type and range of the constraint

Author:

Returns:

double

Implements de::constraint.

Here is the call graph for this function:

double de::real_constraint::get_rand_value	(	double	value,
		double	origin
	)		[inline, virtual]

returns a random value limited to the type and range of the constraint based on a previous value and an origin

Author:

adrian (12/4/2011)

Parameters:

value
origin

Returns:

double

Implements de::constraint.

Here is the call graph for this function:

virtual double de::real_constraint::get_rand_value_in_zone	(	double	origin,
		double	zonePct
	)		const [inline, virtual]

Gets a random value within the limits set for the constraint, but further limited to a range defined by its origin and the width of the zone around this origin in pct of the total width

Author:

adrian (12/13/2011)

Parameters:

origin	the origin (center) of the zone further limiting the constraint
zonePct	the width of the zone in pct of the total width, around the origin

Returns:

double

Implements de::constraint.
