Shape<T extends Shape<T>> class abstract interface

The foundational contract for all 2D entities.

Utilizing the Curiously Recurring Template Pattern (CRTP), Shape ensures that spatial transformations logically return the exact mathematical entity.

Implementers

Properties

area → double
The total surface area of the shape.
no setter
boundingBox → Rectangle
The smallest axis-aligned rectangle that completely encloses the shape.
no setter
centroid → Point<double>
The mathematical center of mass of the shape.
no setter
hashCode → int
The hash code for this object.
no setterinherited
perimeter → double
The total length of the shape's boundary.
no setter
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
rotate(double angle, [Point<num>? origin]) → T
Rotates the shape by the given angle (in radians) around the origin. If origin is omitted, rotates around the shape's centroid.
scale(num factor) → T
Scales the shape uniformly by the given factor originating from centroid.
toString() → String
A string representation of this object.
inherited
translate(Point<num> offset) → T
Translates the shape by the given vector offset.

Operators

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