Defined in:

Overview

Immutable length/angle constraint used when a full segment is not implied.

Instance Attribute Summary

• #angle ⇒ Float readonly

  Direction used to derive a segment.

• #length ⇒ Float readonly

  Non-negative target measure.

Class Method Summary

• .[](length, angle) ⇒ Sevgi::Geometry::LengthAngle

  Creates a length-and-angle constraint.

Instance Method Summary

• #initialize(length:, angle:) ⇒ void constructor

  Creates a target-measure constraint.

Constructor Details

#initialize(length:, angle:) ⇒ void

Creates a target-measure constraint.

Parameters:

• length (Numeric) —

  finite non-negative target width or height

• angle (Numeric) —

  finite direction in degrees

Raises:

• (Sevgi::Geometry::Error) —

  when a component is not finite or length is negative

# File 'lib/sevgi/geometry/segment.rb', line 182

def initialize(length:, angle:)
  length = Real[:length, length]
  Error.("LengthAngle length cannot be negative") if length.negative?

  super(length:, angle: Real[:angle, angle])
end
