Class IntegerVector

Method Details

• addInt

  public void addInt(int val)

  Adds an int to the vector.

• removeIntAt

  public void removeIntAt(int pos)

  Removes an Int from the specified position in the list.

• removeInt

  public void removeInt(int val)

  Removes the first Int found that matched the specified value.

• crop

  public void crop(int start, int end)

  Crops the IntegerVector so it only contains values between start (inclusive) and end (exclusive). So; crop({ 4, 5, 4, 3, 9, 7 }, 0, 3) would return {4, 5, 4) and, crop({ 4, 5, 4, 3, 9, 7 }, 3, 4) would return {3}

• insertIntAt

  public void insertIntAt(int val, int pos)

  Inserts an int at the given position.

• setIntAt

  public int setIntAt(int val, int pos)

  Sets an int at the given position, overwriting anything that was previously there. It returns the value that was previously at the element.

• placeIntAt

  public int placeIntAt(int val, int pos)

  Places an int at the given position, overwriting anything that was previously there. It returns the value that was previously at the element. If 'pos' points to a place outside the bounds of the list then the list is expanded to include this value.

• append

  public IntegerVector append(IntegerVector vec)

  Appends an IntegerVector to the end of the array. Returns this object.

• intAt

  public int intAt(int pos)

  Returns the Int at the given position.

• indexOf

  public int indexOf(int val)

  Returns the first index of the given row in the array, or -1 if not found.

• contains

  public boolean contains(int val)

  Returns true if the vector contains the given value.

• getSize

  public int getSize()

  Returns the size of the vector.

• size

  public int size()

  Returns the size of the vector.

• toIntArray

  public int[] toIntArray()

  Converts the vector into an int[] array.

• clear

  public void clear()

  Clears the object to be re-used.

• toString

  public String toString()

  Converts the vector into a String.

  Overrides:

  toString in class Object

• equals

  public boolean equals(IntegerVector ivec)

  Returns true if this vector is equal to the given vector.

• reverse

  public void reverse()

  Reverses all the list of integers. So integer[0] is swapped with integer[n - 1], integer[1] is swapped with integer[n - 2], etc where n is the size of the vector.

• quickSort

  public final void quickSort(int min, int max)

  Performs a quick sort on the array between the min and max bounds.

• quickSort

  public final void quickSort()

  Performs a quick sort on the entire vector.

• sortedIndexOf

  public final int sortedIndexOf(int val, int lower, int higher)

  This is a very quick search for a value given a sorted array. The search is performed between the lower and higher bounds of the array. If the requested value is not found, it returns the index where the value should be 'inserted' to maintain a sorted list.

• sortedIndexOf

  public final int sortedIndexOf(int val)

  Searches the entire sorted list for the given value and returns the index of it. If the value is not found, it returns the place in the list where the value should be insorted to maintain a sorted list.

• sortedIntCount

  public final int sortedIntCount(int val)

  Given a sorted list, this will return the count of this value in the list. This uses a quick search algorithm so should be quite fast.

• isSorted

  public boolean isSorted()

  Test routine to check vector is sorted.
