class Ray
[source: sims/geometry/Ray.scala]
case class Ray(val point : Vector2D, val direction : Vector2D)
extends scala.Product
Eine Halbgerade wird definiert durch:
Parameters
point - ein Aufpunkt
direction - ein Richtungsvektor
Method Summary
def contains (p : Vector2D) : Boolean
Ueberprueft ob diese Halbgerade den gegebenen Punkt enthaelt.
Hierzu wird der Vektor von dem Ursprungspunkt zu dem zu ueberpruefenden Punkt gebildet. Dieser wird dann mit dem Richtungsvektor auf Kolinearitaet geprueft.
override def equals (arg0 : Any) : Boolean
This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.
override def hashCode : Int
Returns a hash code value for the object.
def intersects (s : Segment) : Boolean
Ueberprueft ob diese Halbgerade das gegebene Segment ueberschneidet.
override def productArity : Int
override def productElement (arg0 : Int) : Any
override def productPrefix : java.lang.String
override def toString : java.lang.String
Returns a string representation of the object.

Method Details
def intersects(s : Segment) : Boolean
Ueberprueft ob diese Halbgerade das gegebene Segment ueberschneidet.
Parameters
das - auf Ueberschneidung zu uerberpruefende Segment
def contains(p : Vector2D) : Boolean
Ueberprueft ob diese Halbgerade den gegebenen Punkt enthaelt.
Hierzu wird der Vektor von dem Ursprungspunkt zu dem zu ueberpruefenden Punkt gebildet. Dieser wird dann mit dem Richtungsvektor auf Kolinearitaet geprueft.
Parameters
p - Ortsvektor des oben genannten Punkt
override def hashCode : Int
Returns a hash code value for the object.

The default hashing algorithm is platform dependent. Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

Returns
the hash code value for the object.

override def toString : java.lang.String
Returns a string representation of the object.

The default representation is platform dependent.

Returns
a string representation of the object.

override def equals(arg0 : Any) : Boolean
This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.

The default implementations of this method is an equivalence relation:

  • It is reflexive: for any instance x of type Any, x.equals(x) should return true.
  • It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any instances x, y, and z of type AnyRef if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is often necessary to override hashCode to ensure that objects that are "equal" (o1.equals(o2) returns true) hash to the same Int (o1.hashCode.equals(o2.hashCode)).

Parameters
arg0 - the object to compare against this object for equality.
Returns
true if the receiver object is equivalent to the argument; false otherwise.
