class Projection
[source: sims/geometry/Projection.scala]
case class Projection(val axis : Vector2D, val lower : Double, val upper : Double)
extends scala.Product
Projektion auf eine Achse.

Ueblicherweise werden Projektionen in SiMS fuer Kollisionserkennung benutzt.

Parameters
axis - Achse der Projektion
lower - unterer Wert der Projektion
upper - oberer Wert der Projektion
Method Summary
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 overlap (other : Projection) : Double
Ergibt die Ueberlappung dieser Projektion und der Projektion other.
def overlaps (other : Projection) : Boolean
Ueberprueft ob sich diese Projektion mit der Projektion other 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 overlaps(other : Projection) : Boolean
Ueberprueft ob sich diese Projektion mit der Projektion other ueberschneidet.
def overlap(other : Projection) : Double
Ergibt die Ueberlappung dieser Projektion und der Projektion other.
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.
