Class PrimitiveList

  • Direct Known Subclasses:
    ByteList, DoubleList, FloatList, IntList, LongList, ShortList

    public abstract class PrimitiveList
    extends java.lang.Object
    Provides an extendable list of primitive values. This provides an abstract superclass for concrete implementations which do roughly the same job for numeric primitive types that StringBuffer does for chars and List does for Objects.

      Constructors 
      Modifier Constructor Description
      protected PrimitiveList​(java.lang.Object array, int size)
      Constructs a list from an initial array object, whose component type determines the primitive type which this list will work with, and a size, which indicates number of elements of the array which are initially considered to constitute the contents of this list.

      Modifier and Type Method Description
      protected int nextCapacity​(int currentCapacity)
      Determines by how much the storage array will grow if it needs to expand.
      int size()
      Returns the current size of this list.
      java.lang.Object toArray()
      Creates and returns a copy of the contents of this list, in the form of a primitive array of the right length to hold all the elements it currently contains.

      • PrimitiveList

        protected PrimitiveList​(java.lang.Object array,
                                int size)
        Constructs a list from an initial array object, whose component type determines the primitive type which this list will work with, and a size, which indicates number of elements of the array which are initially considered to constitute the contents of this list.
        Parameters:
        array - array object
        size - initial list size (note, not capacity)
    • Method Detail

      • size

        public int size()
        Returns the current size of this list.
        Returns:
        number of elements which have been stored
      • toArray

        public java.lang.Object toArray()
        Creates and returns a copy of the contents of this list, in the form of a primitive array of the right length to hold all the elements it currently contains.
        Returns:
        array containing contents of this list
      • nextCapacity

        protected int nextCapacity​(int currentCapacity)
        Determines by how much the storage array will grow if it needs to expand. Any return value is legal; if a value less than the currentCapacity is returned, Integer.MAX_VALUE will be used. The effect of this is that implementations probably do not need to worry about integer arithmetic overflow. May be overridden by subclasses.
        Parameters:
        currentCapacity - initial size of buffer
        Returns:
        next size up
