Constructor Detail
Vector
protected Vector()(Code)
Default constructor (for sub-classes).




Method Detail
copy
abstract public Vector<F> copy()(Code)
Returns a copy of this vector javolution.context.AllocatorContext allocated by the calling thread (possibly on the stack). an identical and independant copy of this matrix.



cross
public Vector<F> cross(Vector<F> that)(Code)
Returns the cross product of two 3-dimensional vectors.
Parameters:
  that - the vector multiplier. this x that
throws:
  DimensionException - if (this.getDimension() != 3) && (that.getDimension() != 3)



equals
public boolean equals(Vector<F> that, Comparator<F> cmp)(Code)
Indicates if this vector can be considered equals to the one specified using the specified comparator when testing for element equality. The specified comparator may allow for some tolerance in the difference between the vector elements.
Parameters:
  that - the vector to compare for equality.
Parameters:
  cmp - the comparator to use when testing for element equality. true if this vector and the specified matrix areboth vector with equal elements according to the specifiedcomparator; false otherwise.



equals
public boolean equals(Object that)(Code)
Indicates if this vector is equal to the object specified.
Parameters:
  that - the object to compare for equality. true if this vector and the specified object areboth vectors with equal elements; false otherwise.



get
abstract public F get(int i)(Code)
Returns a single element from this vector.
Parameters:
  i - the element index (range [0..n[). the element at i.
throws:
  IndexOutOfBoundsException - (i < 0) || (i >= size())



getDimension
abstract public int getDimension()(Code)
Returns the number of elements held by this vector. this vector dimension.



hashCode
public int hashCode()(Code)
Returns a hash code value for this vector. Equals objects have equal hash codes. this vector hash code value.
See Also:   Vector.equals



minus
public Vector<F> minus(Vector<F> that)(Code)
Returns the difference between this vector and the one specified.
Parameters:
  that - the vector to be subtracted. this - that.



opposite
abstract public Vector<F> opposite()(Code)
Returns the negation of this vector. -this.



plus
abstract public Vector<F> plus(Vector<F> that)(Code)
Returns the sum of this vector with the one specified.
Parameters:
  that - the vector to be added. this + that.
throws:
  DimensionException - is vectors dimensions are different.



times
abstract public Vector<F> times(F k)(Code)
Returns the product of this vector with the specified coefficient.
Parameters:
  k - the coefficient multiplier. this · k



times
abstract public F times(Vector<F> that)(Code)
Returns the dot product of this vector with the one specified.
Parameters:
  that - the vector multiplier. this · that
throws:
  DimensionException - if this.dimension() != that.dimension()
