Class SimpleLongArrayList

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable

    public class SimpleLongArrayList
    extends AbstractLongList
    Resizable list holding long elements; implemented with arrays; not efficient; just to demonstrate which methods you must override to implement a fully functional list. First see the package summary and javadoc tree view to get the broad picture.

    • Field Detail

      • elements

        protected long[] elements
        The array buffer into which the elements of the list are stored. The capacity of the list is the length of this array buffer.
      • size

        protected int size
        The size of the list.
    • Constructor Detail

      • SimpleLongArrayList

        public SimpleLongArrayList()
        Constructs an empty list.
      • SimpleLongArrayList

        public SimpleLongArrayList​(long[] elements)
        Constructs a list containing the specified elements. The initial size and capacity of the list is the length of the array. WARNING: For efficiency reasons and to keep memory usage low, the array is not copied. So if subsequently you modify the specified array directly via the [] operator, be sure you know what you're doing.
        Parameters:
        elements - the array to be backed by the the constructed list
      • SimpleLongArrayList

        public SimpleLongArrayList​(int initialCapacity)
        Constructs an empty list with the specified initial capacity.
        Parameters:
        initialCapacity - the number of elements the receiver can hold without auto-expanding itself by allocating new internal memory.
    • Method Detail

      • ensureCapacity

        public void ensureCapacity​(int minCapacity)
        Ensures that the receiver can hold at least the specified number of elements without needing to allocate new internal memory. If necessary, allocates new internal memory and increases the capacity of the receiver.
        Specified by:
        ensureCapacity in class AbstractLongList
        Parameters:
        minCapacity - the desired minimum capacity.
      • getQuick

        protected long getQuick​(int index)
        Returns the element at the specified position in the receiver; WARNING: Does not check preconditions. Provided with invalid parameters this method may return invalid elements without throwing any exception! You should only use this method when you are absolutely sure that the index is within bounds. Precondition (unchecked): index >= 0 && index < size().
        Specified by:
        getQuick in class AbstractLongList
        Parameters:
        index - index of element to return.
      • setQuick

        protected void setQuick​(int index,
                                long element)
        Replaces the element at the specified position in the receiver with the specified element; WARNING: Does not check preconditions. Provided with invalid parameters this method may access invalid indexes without throwing any exception! You should only use this method when you are absolutely sure that the index is within bounds. Precondition (unchecked): index >= 0 && index < size().
        Specified by:
        setQuick in class AbstractLongList
        Parameters:
        index - index of element to replace.
        element - element to be stored at the specified position.
      • trimToSize

        public void trimToSize()
        Trims the capacity of the receiver to be the receiver's current size. An application can use this operation to minimize the storage of the receiver.
        Overrides:
        trimToSize in class AbstractList
