SingularInterval class

A fixed numerical interval where the start point coincides with the end point.

The method next() returns the only point in the interval.
The method perturb(position, deltaPosition) returns the only point in the interval if it coincides with position.

The class is used for example to specify the radius of a surface of a sphere.

SingularInterval(num value, {String name = ''}): Constructs a singular fixed interval.
SingularInterval.of(SingularInterval interval)

dx → Lazy<num>: Step size between discrete levels.
latefinalinherited
end → num: End point of the numerical interval.
finalinherited
gridPoints → List<num>: Returns the grid points associated with the discrete interval.
no setterinherited
hashCode → int: The hash code for this object.
no setterinherited
inverseCdf → InverseCdf?: Inverse cummulative distribution function.
finalinherited
isContinuous → bool: Returns true if the interval is continuous.
no setterinherited
isDiscrete → bool: Returns true if the interval is discrete (has at least 2 gridpoints).
no setterinherited
isUpToDate → bool: Returns true is the cached random numbers are up-to-date.
no setterinherited
levels ↔ int: Returns the levels of a discrete interval.
getter/setter pairinherited
name → String: Returns the name of interval.
finalinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
size → num: Returns the size of the interval.
latefinalinherited
start → num: Start point of the numerical interval.
finalinherited

contains(num position) → bool: Returns true if position coincides with start.
override
next() → num: Returns the singular value `start.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
overlaps(num left, num right) → bool: Returns true if the interval defined by the points left and right overlaps this.
inherited
perturb(num position, num deltaPosition) → num: Returns position if start == position. Returns double.nan otherwise.
override
toString() → String: A string representation of this object.
inherited
updateCache() → void: Marks the internal cache as stale. After calling this function the methods next and perturb will return a new random number sampled from the interval start...end.
