public class booleanVector
extends java.lang.Object

This class defines a dynamic vector of type intger.

Constructor Summary

booleanVector()
Allocates an empty vector.

booleanVector(boolean[] vec)
Allocates a vector from the array vec.

booleanVector(booleanVector x)
Make a copy of the vector x.

booleanVector(int n)
Allocates a vector of size n with initiařized values 0.

Method Summary

void	add(boolean x) Add an element of value x to the vector.
void	append(booleanVector x) Append an booleanVector x to this vector
void	concat(booleanVector x) Append a booleanVector x to this vector
static booleanVector	copy(booleanVector x) Make a copy of the vector x.
boolean	elementAt(int i) return the value of vector at index i.
boolean[]	getData() Make an boolean array that contains all data of the vector.
static booleanVector	ones(int n) Make a booleanVector of length n whose elements have value true.
void	print() Print all elements of the vector using System.out.
void	resize(int n) Change the size of the vector to n.
void	setElementAt(boolean x, int i) change the value of element at index i with the integer x.
int	size() Return the length of the vector.
booleanVector	subvector(int from) make a vector whose elements are equal to elements of this vector with the indexes from an integer "from" to the end of this vector.
booleanVector	subvector(int from, int to) Make a vector whose elements are equal to elements of this vector with the indexes from an integer "from" to an intger "to".
java.lang.String	toString() create a String that contains the elements of the vector.
void	trimToSize() Remove all the unused elements of the vector.
static booleanVector	zeros(int n) Make a booleanVector of length n whose elements have value false.
