public class: IntList [javadoc | source]

java.lang.Object
   org.jfree.report.util.IntList

A Array-List for integer objects. Ints can be added to the list and will be stored in an int-array.

Using this list for storing ints is much faster than creating java.lang.Integer objects and storing them in an ArrayList.

This list is not synchronized and does not implement the full List interface. In fact, this list can only be used to add new values or to clear the complete list.

Constructor:

Constructor:
public IntList(int capacity) { data = new int[capacity]; increment = capacity; } Creates a new IntList with the given initial capacity. The capacity will also be used as increment value when extending the capacity of the list. Parameters: `capacity` - the initial capacity.

 public IntList(int capacity) {
                                   
    data = new int[capacity];
    increment = capacity;
}

Creates a new IntList with the given initial capacity. The capacity will also be used as increment value when extending the capacity of the list.

Parameters:

capacity - the initial capacity.

Method from org.jfree.report.util.IntList Detail:

 public  void add(int value) {
    ensureCapacity(size);
    data[size] = value;
    size += 1;
}

    if (index  >= size || index <  0)
    {
      throw new IndexOutOfBoundsException(String.valueOf(index));
    }
    return data[index];
}

Returns the value at the given index.

 public int size() {
    return size;
}

Returns the number of elements in this list.

 public int[] toArray() {
    if (size == 0)
    {
      return IntList.EMPTY_ARRAY;
    }
    final int[] retval = new int[size];
    System.arraycopy(data, 0, retval, 0, size);
