ParametricInterval class
A numerical interval defined by
the parametric start point function startFunc
and the end
point endFunc
.
Constructors
- ParametricInterval(ParametricPoint startFunc, ParametricPoint endFunc, {InverseCdf? inverseCdf, String name = ''})
-
Constructs a parametric interval defined by
the parametric start point function
startFunc
and the end point functionendFunc
. - ParametricInterval.of(ParametricInterval interval)
-
Constructs a copy of
interval
.
Properties
-
dx
→ Lazy<
num> -
Step size between discrete levels.
latefinalinherited
- end → num
-
The end of the numerical interval start...end.
no setteroverride
- endFunc → ParametricPoint
-
End point of the numerical interval.
final
-
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.

- 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.

- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- size → num
-
Returns the size of the interval.
no setterinherited
- start → num
-
The start of the numerical interval start...end.
no setteroverride
- startFunc → ParametricPoint
-

Methods
-
contains(
num position) → bool -
Returns true if position is safisfying
(start <= position && position <= end)
.inherited -
next(
) → num -
Returns the next random number sampled from
the interval
(start, end)
.inherited -
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
andright
overlapsthis
.inherited -
perturb(
num position, num deltaPosition) → num -
Returns the next random number sampled from the interval
obtained by intersecting:
(start, end)
and(position - deltaPosition, position + deltaPosition)
.inherited -
toString(
) → String -
A string representation of this object.
override
-
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

Operators
-
operator ==(
Object other) → bool -
The equality operator.
