public class Vect
extends java.lang.Object
implements java.lang.Cloneable, java.io.Serializable

The Vect class is a copy of the standard java.util.Vector class, with the 'synchronized' support removed (for performance reasons). Also added is a constructor to quickly create a vect from a vector.

Field Detail

elementData

Deprecated. 
The array buffer into which the components of the vector are stored. The capacity of the vector is the length of this array buffer.


elementCount
